How to use the RTM professional torch
Dear Customer:
Thank you for choosing RTM products.
For qualified torches, the flame temperature is inversely high proportional to the heating time,
noise and gas consumption, that is to say: to obtain the desired heat in a relatively short time,
with its lowest gas consumption and noise, during which, especially when it’s a stable long-time
flaming, the tip temperature is an important parameter to evaluate the quality of the torch.
There are some essential differences between traditional oxygen-acetylene torch and
single-gas torch.
For the former: the fuel and oxygen adjust themselves to get the proper ratio to burn, to reach
the welding temperature, the flame is burning outside the tip, therefore the tip temperature is only
from radiant heat.
The single-gas torch is using the oxygen in the air to support combustion, to meet the welding
temperature, which relies on inhaling air automatically when the fuel goes through the nozzle with
a relatively high velocity, therefore the tip temperature is totally dependent on the air flow.
When the valve opens too small, due to the lower air velocity at the nozzle, less air is inhaled,
the needs of combustion can not be met, so the flame is burning inside the nozzle, in this
situation, it will not only fail to reach the welding temperature, but also make the tip burn red,
even worse the automatic-ignition system and bronze head burn down. When the valve opens too
big, due to the too high air velocity at the nozzle, too much air is taken in, in this situation, it will
leave the flame burning far from the nozzle, a "fire off" phenomenon, because the inhalation of too
much cold air, the nozzle’s tip temperature gets down instead. Since the flame is dispersed, on
the one hand it wastes the fuel, on the other hand it reduces the welding temperature.
After igniting, if the valve opening is adjusted correctly, you will get the right flame as a
"writing-brush shape", the flame is burning at the nozzle’s outlet, tip’s temperature is at 60 ~ 80oC.
When the flame is dispersed, which indicates the valve opens too big, the tip is cold; when the
flame is elongated, internal and external flames are indistinct, the flame is burning inside the tip,
it can easily cause the red-hot tip, and even worse the burned-down ignition system.
To weld small-diameter pipes, adjusting the valve opening to get smaller flame can not be
adopted, a substituted smaller nozzle assembly is advised in the situation. The easiest way is
moving the flame away from the object or using the propane gas cylinder.

How to use the RTM professional torch
Generally speaking, fresh users will adjust valve opening smaller, thinking that it can save gas,
however that is bound to take more time for welding and even worse damage the torch. For
example, to weld Ф40 joint, under normal circumstances, it takes less than a minute, which can
not overheat or damage the tip. When manufacturers experiment on torch models at factory, they
let one whole cylinder of gas burn completely to test its basic functions, it will last 160 minutes
or more to test the stability and other parameters.

RTM Advanced Design
Reasonable secondary liquid-gas separation device (Efficiency)
The pressure reducing device of the RTM hand torch is independently installed in the brass
shell with needle assembly and decompression assembly separately. It uses austenitic stainless
steel for critical parts, which helps to prevent the corrosion from detrimental impurities. The
sufficient space in needle assembly allows the secondary liquid-gas separation device to be
easily settled inside and thoroughly gasify the residual liquid, which ensures the stability of the
combustion and maximize the thermal efficiency. Instead, other brands just install the secondary
separation device in the front of the nozzle since they use valve core and valve components to
replace RTM needle assembly, resulting in insufficient space for the device. It has following two
disadvantages:
1. The inadequate gasification of the residual liquid will cause the blocking nozzle;
2. The inadequate gasification of the detrimental impurities will cause the corrosion of the nozzle,
resulting in lower welding temperature and thermal efficiency.
Solid liner material (safety)
The minimum thickness of RTM torch liner is 1.4mm while other brands only have 0.3mm.The
tensile strength will be decreased after stretching and there might be security risks for the thin
liner expose to the pressure inside the cylinder (20 oC ≧ 1Mpa).
Proper valve switch design, 100% spring reset and cut off the gas channel (safety)
The reaction force spring assist design in RTM valve switch guarantee the 100% reset and
shutdown even if it can not close smoothly by various complex factors. But for other brand
torches the flame will not shutdown after releasing the switch in such situation and it has a
certain risk when facing of unconventional welding conditions such as gas leakage.
RTM Advanced Features
High Efficiency
Firstly, to avoid the defect in the surface, there is enough nitrogen up to 70%-80% which can
keep away from the oxygen, and the carbon monoxide in the welding surface will reducation the
heated metal, improving the soldering quality.
Secondly, for the hot value, example of our RTM-030 that is 13670BTU/hour with the five swirl
flame, much higher than other brands.
Lastly, absolutly using of the gas, in terms of the design of “L” type hole in the bottom side,
RTM torch can still consume the gas even if there is few in the bottle with low pressure.
Almightiness
Firstly, flexible adjustment of the flame can meet the different requirement of soldering metal.
