Welding operation

Structural and stainless steels are welded using direct current with the electrode negative pole.

Light alloys are welded using alternating current: when polarity alternation reverses, the flow of electrons from the plate to the electrode cracks the layerof refractory aluminum. On the following alternation, the direct polarity ensures penetration.

TIG welding glossaryEuropean CE standardsThey guarantee a quality of construction, chemical and mechanicalcharacteristics and a level of safety. All Oerlikon generators have CEcertification. They impose construction according to European directives.• Directive 89/336 imposes limitation of emissions of electromagnetic

interferences.• The low voltage directives impose manufacturing, safety and

performance rules.EN 60974-1, device capacities are given according to a welding currentdelivered at a given duty cycle.Duty cycleIt is defined in the standard. The duty cycle is the duration of continuoususe of a device, based on a time of 10 minutes at a temperature of -40°C. A duty cycle of 100 A at 60% means that over a period of 10minutes, it is possible to weld continuously for 6 minutes, followed by astop of 4 minutes. A duty cycle of 100 A at 100% means that the sourceis designed to deliver 100 A continuously.Pre-gasUsed to purge the torch pipes before welding in order to start welding inan atmosphere of protective gas.Preheating stageAllows positioning on the joint and preheating of the metal to be welded.Rise rampMakes it possible to reach the welding current level progressively.Arc fadingAvoids the crater (shrinkage cavity) at the end of the bead when weldingstops.End settingAllows slower cooling of the weld pool and selection of a “lighted arc”welding cycle, which is very useful when welding in position.

CITOSTEPUsed to adjust two distinct current levels via a signal from the torchtrigger.Post-gasProtects the weld pool and tungsten electrode during cooling.BalanceAllows welding using alternating current (light alloys) to favour cleaning orpenetration.Pulsed systemAvoids collaps of the weld pool during welding of thin thicknesses bytime phasing the welding current between a high value (hot time) and alow value (cold time).ClampingSaves time during spot welding operations by avoiding having to gothrough the whole welding cycle.HF arc strikingSystem involving a distant striking of the electric arc without contactbetween the tungsten electrode and the part to be welded.Arc striking on contactSystem involving striking of the electric arc as soon as the torch is raisedafter contact has been made between the part and the tungstenelectrode. This mode is particularly useful when operating inenvironments that are sensitive to high-frequency interference.Square wavesIn alternating current, the square form of current waves ensures excellentarc stability and avoids arc disruption when the current changesdirection.IP protection classThe first figure indicates the maximum diameter of an object able topenetrate the device and come in contact with a dangerous part. Thesecond figure indicates the level of protection against falling rain.Example: IP 23 - the “2” indicates that an object with a diameter greaterthan 12.5mm may not be introduced into the device - the “3” indicatesthat it is not damaged by rainfall at an angle of 60°.
