Oxy-Fuel Cutting Techniques for Flame Cutting MachinesDescription of processes and equipment Process
Messer Cutting & Welding GmbH 722.28092.004 7
Oxy-fuel flame cutting is that thermal cutting process which is executed with a fuelgas/oxygen flame and cutting oxygen.The material is heated locally to ignition temperature and combusted at this point inthe stream of cutting oxygen. The heat which is produced by the heating flame andon combustion of the material permits a continuous process of combustion in thestream of cutting oxygen. The reaction is propagating in the depth and - uponmovement - in the feed direction. The oxides produced mixed with melt metal —also called cutting slag — are ejected by the cutting oxygen jet, thereby producingthe cutting kerf.
Flame cutting of materials is only possible if they meet the following requirements:
• The material heated to ignition temperature must combust in the oxygen streamproducing fluid oxides which can be ejected.
• The ignition temperature of the material must be below its melting point.• The combustion heat of the material must be as great as possible and its
thermal conductivity as low as possible.
These requirements are met by all structural steels, many low-alloy steels and steelcastings as well as titanium.
Please note:Accident prevention regulations for oxygen (VBG 62), Technical regulationsfor acetylene plants and calcium carbide stores (TRAC), Safety devices forsewer gas, long-distance gas, natural gas (methane) and liquid gas (e.g.propane, butane) DVGW memorandum G 606.
OxygenAccording to requirements, it is possible to use batteries or bundles of cylinders, orcold vaporizers. Depending on the facilities available, the flame cutting machine canbe supplied via the works system or directly from the gas supply source.
Fuel gas• Acetylene
Dependent on the consumption level, batteries or bundles of cylinders, orgenerators may be used for supplying acetylene.
• Fuel gas mixtures (Methyl-acetylene-propadiene mixtures (Mapp gas etc.)Dependent on the consumption level, Mapp gas is supplied by single cylinders,cylinder batteries or tanks.
• PropaneGenerally, a liquid gas tank with vaporizing station is installed for supplyingpropane.
• Natural gasNatural gas is provided via pipelines. The minimum pressure at the torch inletmust be observed (see cutting tables).

Use hoses that comply with EN 559. The specification of DIN 8541, part 2, appliesto sheathed hoses. Use hoses that comply with DIN 4815 for liquid gas.
Identification colors:Oxygen: blueFuel gas (except liquid gas): redPropane/butane/fuel gas mixtures(Methyl-acetylene-propadiene mixtures, e. g. Mapp): orangeCompressed air: black
Hoses must be secured with suitable hose clips or hose joints. The length of thehose should be such that it does not impede the travel of the cross-carriage.Do not confuse the hoses for heating and cutting oxygen. Connections comply withEN 560.
Dependent on the type of machine, pressure regulators are located at the extractionpoint or at the central control of the machine.
All regulators are of the directly controlled, proportional type. The valve cone iscontrolled via a diaphragm by means of the interaction of gas pressure and springpressure or control pressure. The outlet pressure remains constant even in theevent of fluctuating inlet pressures.
The gas throughput of the pressure regulators incorporated in the machinecorresponds with the performance range of the machine.
If no pressure regulators are incorporated in the machine, it is necessary to selectextraction point pressure regulators which correspond with the maximum gasthroughput.(On this subject please refer to Art. no. 0.810.111)

Oxy-Fuel Cutting Techniques for Flame Cutting MachinesGeneral remarks Safety
Messer Cutting & Welding GmbH 722.28092.00410
Oxy-fuel flame cutting is that thermal cutting process which is executed with a fuelgas/oxygen flame and cutting oxygen.
The machine must not be started up without the prescribed safety device mountedat the extraction point of the central fuel gas supply line.
The user must use the fuel gas specified for the machine.
The machine cutting torches should be operated exclusively with the fuel gas forwhich they are marked. The Messer Cutting & Welding machine cutting torches areto be combined only with the corresponding cutting nozzles fromMesser Cutting & Welding of the same type of gas.
When switched on the machine must be under the supervision of the operatingpersonnel.
Within the working range of the machine, sufficient clearance is to be kept torotating units, oppositely directed torch carriages or similar equipment.
Before starting work (change of shift), the operating personnel must make sure thatthe machine, in particular the cutting torch, is ready for operation. The screwconnections of the gas piping and at the torch must be tightened firmly and gas-tight.
All adjustment valves on non-used machine cutting torches must be closed byhand.
Ignition, adjustment and extinguishing of the flame are to be carried out inaccordance with the instruction manual. (See section "Igniting and adjusting theflame").
To prevent the risk of fire and explosions it is absolutely essential to eliminateuncontrolled outflows of gas or gas mixtures. This is particularly the case whencutting tables that incorporate water tanks and fume extraction units are being used.
For manual ignition of the torches only suitable gas igniters should be used.
Check after electric ignition that all preselected torches have ignited.
In case of clogged flame cutting nozzles, after flame flashback or backfiring,immediately close the adjustment valves for fuel gas, heating oxygen, cuttingoxygen by hand in the given order.
The individual gas connections on exchangeable assemblies, such as single torch,triple-torch assembly, must be made workmanlike. When the assemblies are notconnected, the supply lines for exchangeable assemblies are to be closed gas-tight.

Use only original nozzles from Messer Cutting & Welding!Only clean and undamaged nozzles will guarantee the output mentioned above.
For cutting oxygen, heating oxygen and fuel gas. With the valves open – centralcontrol and torch valves – set the pressure in accordance with the details statedin the cutting table by turning the adjusting screw on the pressure regulator (section"Operating data for machine flame cutting nozzles").
For measuring the pressures at the torch inlet, test pressure gauges are availablewhich are to be installed between the machine cutting torches and the torchadjustment valves. See figure 1–1.
Close the central control and torch valves again. When the cutting operation hasbeen completed or interrupted for a longer period of time, relieve the pressureregulators by turning back the adjusting screws and close the extraction pointvalves.

When the gas pressures have been set at the pressure regulators, open all centralcontrol valves.
At each individual torch:fully open the heating oxygen valve, open the fuel gasvalve slightly, allow the issuing gas mixture to flow uncombusted for a few seconds,then ignite and set a neutral flame.
During ignition, the torches must be at least 100 mm above the workpiecesurface.
Acetylene/Oxygen
With the heating oxygen valve open, first set surplus acetylene with the fuel gasvalve on the cutting torch (identified by the "licking", undefined, luminous flamecone A, Fig. 3–1). Then reduce the acetylene supply until the longest – still sharplydefined – cone is obtained; see B, Fig. 3–1.
Since the heating flame has to provide only a certain proportion of the thermalenergy required for the cutting process, it must be adjusted accordingly, i.e. it isuneconomical if the heating flame is too large, especially as the desired sharpnessof the cut edge is also adversely affected.
The size of the heating flame is set with the heating oxygen valve of the torch, thevolume of fuel gas for the neutral flame being proportioned at the same time usingthe fuel gas valve.Check the cutting oxygen jet. It must flow in a straight, cylindrical form from thenozzle and must not flutter; The heating flame must surround the oxygen jetconcentrically (see C, Fig. 3–1).
When each torch has been set individually — as described above —, it is onlynecessary to operate the central control valves. The corresponding cutting oxygenvalves for the individual torches remain open at all times, whilst the individualheating oxygen and fuel gas valves are used only as adjustment valves.
If it is necessary to turn off an individual torch, first close the cutting oxygen valve,then the fuel gas valve and finally the heating oxygen valve.
Propane/oxygen, Mapp/oxygen, methane/oxygen, town gas/oxygen
In the case of slow-combusting gases such as propane, Mapp, methane and towngas, it is not quite as easy to recognize the correct flame setting for flame cutting.With some practice, however, it is possible to identify the most economic setting forthese gases, too, by the size and color of the flame.

Protect torches from damage. Keep the nozzles clean at all times and, if dirty, useonly suitable nozzle cleaners, wire brushes or nozzle cleaning powder. Please payattention to the detailed "Maintenance instructions for flame cutting nozzles".
Soiled and damaged nozzles impair the cutting quality and flashback safety of thetorch. (See also maintenance instructions for heavy-duty flame cutting nozzles,Art. no. 0.810.996).
The flame arresters of the nonreturn valves are made of sintered metal and aresoiled in the course of time by carbon deposits resulting from flashbacks or dirt fromthe supply lines. This increases the pressure loss and impairs the function of thetorch.
Therefore, the nonreturn valves are to be replaced dependent on the dirtproduced.
In the event of flashback, the flame penetrates into the torch where it continues toburn in the mixing zone, producing whistling, hissing noises. In order to preventdamage to, or even destruction of the torch, immediately close the valves in thefollowing order:
• fuel gas valve• heating oxygen valve at the corresponding torch• cutting oxygen valve
Then allow the torch to cool down and remedy the defect. Should flashback recur,we recommend that the torch is passed to an authorized workshop for inspectionand repair.

Set clearance between nozzle and surface of workpiece in accordance with thecutting table. Position the torch suspension in the direction of the cut so that thecutting jet does not "grub up" the workpiece surface.When the ignition temperature is reached, turn on the cutting oxygen and switch onthe machine drive. The cutting jet must produce sharp edges when starting the cut..
If the cut is to be started at a whole within the workpiece, the starting hole can be"pierced" in the following ways:
by means of hand cutting torchPreheat the piercing point well. When the material has been heated up to its ignitiontemperature, slightly incline the torch and, at the same time, gradually open thecutting oxygen valve. Then swivel the torch until the torch head is in a verticalposition.
by means of machine cutting torch (Fig. 3–8):Ignite the fuel gases, set nozzle clearance according to table and heat the materialto ignition temperature. Then switch on the machine drive and gradually open thecutting O2 valve (proportioning valve) so that the molten material does not damagethe nozzle.

Oxy-Fuel Cutting Techniques for Flame Cutting MachinesOverview Maintenance instructions for flame cutting nozzles
Messer Cutting & Welding GmbH 722.28092.004 39
Heavy-duty flame cutting nozzles are of high cutting performance and a long servicelife. They are manufactured with great precision, carefully checked and packed sothat damage during transport is being excluded.
Corrosion protective agents, rust and scale on the surface of the sheets to be cut aswell as slag spatter are the reasons for deposits, contamination or damage to thecutting nozzles. The nozzles must be cleaned.
Wet cleaning
A simple and protective way of nozzle cleaning is wet cleaning.
For this purpose, usually 50 g of nozzle cleaning powder (art. no. 733.00514) aredissolved in 1 l of tap water. The cutting nozzles to be cleaned are put into thesolution for 8–12 hours (according to the degree of contamination). Then they arerinsed with flowing water and dried.
Protective measures must be observed when dealing with the solution(see instructions for use).
Mechanical cleaning
Slight contamination on the face of the cutting nozzles and within the direct vicinityof the mouth of the preheat flues of the cutting O2 conduit can be removed bymeans of a soft brass brush (art. no. 052.04020).

Cleaning the cutting oxygen conduit
The tightest orifice (section 1, Fig. 4–1) of the cutting O2 conduit is cleaned with asuitable nozzle needle (art. no. 716.01085).
Contamination of the conic or conic/cylindrical widening (section 2, Fig. 4–1) areeffectively removed by wet cleaning (see section "Wet cleaning").
Fig. 4–1: Cutting oxygen conduit, nozzle needle
Minor contamination and slight burring deposits at the nozzle exit edge (Fig. 4–2)can be removed with the tapered nozzle cleaning needle (art. no. 716.01879).

Messer Cutting & Welding GmbH 722.28092.004 43
Important hint for the use of gas-mixing nozzlesBecause of their high operating reliability, gas-mixing nozzles are used preferably insites where high thermal stress must be reckoned with. When nozzles are changedor especially when new nozzles are used, it is important to strongly tighten thethumbscrew so that the sealing surfaces of the nozzles may adjust to the sealingsurfaces of the torch head (see Fig. 4–6).
In case of extreme heating of cutting nozzle and torch head and subsequent coolingdown, it may happen that the nozzle in the torch head loosens and gets leaky.Therefore the thumbscrew must be tightened again after the first thermal stress.Thereby it is necessary to apply a countergrip on the torch head with the torchspanner.
Damaged sealing faces in the torch head or on the nozzle must be reconditioned bymeans of suitable milling tools (see Fig. 4–7 and Fig. 4–8).See VBG 15.
Only unobjectionable torches and nozzles guarantee good sealing, reliable work,long service life and the optimum cutting result.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machines areused. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form ofkerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables VADURA® 1210-A /8043 Ay dm or VADURA® 1210-A 8043 Ak dm are valid. The pressures stated are excess pressuresmeasured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates and sheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved -provided that suitable flame cutting machines are used. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 300
by 25 % approx., for bevel cuts of 450 by 45 % approx. For Y cuts (form of kerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 8281-PMY 8043 Pydm or GRICUT® 8281-PMY 8043 Pk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machines areused. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form ofkerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 1230-/1280-PMYF 8051 Py dm or GRICUT®1230-/1280-PMYF 8051 Pk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates and sheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved -provided that suitable flame cutting machines are used. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30°
by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form of kerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables LP-N 8070 My dm or LP-N8070 Mk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machines areused. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form ofkerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 1230-/1280-PmYF 8051 My dm or GRICUT®1230-/1280-PMYF 8051 Mk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machines areused. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form ofkerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 8280-PMYF 8072 My dm or GRICUT® 8280-PMYF 8072 Mk dm are valid. The pressures stated are excesspressures measured at the torch inlet. The consumption data indicated in m3 /h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machinesare used. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts(form of kerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 1230-/1280-PMYF 8038 Yy dm or GRICUT®1230-/1280-PMYF 8038 Yk dm are valid. The pressures statedare excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machines areused. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts (form ofkerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 8280-PMYF 8073 Yy dm or GRICUT® 8280-PMYF 8073 Yk dm are valid. The pressures stated are excess pressuresmeasured at the torch inlet. The consumption data indicated in m3 /h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO 9013 are achieved - provided that suitable flame cutting machinesare used. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts(form of kerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 1270-PYF/1280-PMYF 7079 Yy dm or GRICUT®1270-PYF/1280-PYF 7079 Yk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.

The table indicates standard values based on the use of plain steel with a carbon content of up to 0.3 % and oxygen with a minimum purity of 99.5 %. Satisfactory cuts on clean and non-primed plates andsheets can only be achieved with undamaged nozzles. With the given cutting speeds, cut surfaces of the quality class I according to EN ISO – 9013 are achieved - provided that suitable flame cutting machinesare used. The cutting speeds stated are to be reduced as follows: for shape cutting involving small radii by 10% approx., for bevel cuts of 30° by 25 % approx., for bevel cuts of 45° by 45 % approx. For Y cuts(form of kerf Y as per DIN 8551) and K cuts (form of kerf DHY as per DIN 8551) the tables GRICUT® 1230-/1280-PMYF 9088 Fy dm or GRICUT®1230-/1280-PMYF 9088 Fk dm are valid.The stated pressures are excess pressures measured at the torch inlet. The consumption data indicated in m3/h apply to the standard condition as per DIN 1343.
