Intended Use; Technical Data / Range Of Application; Function Of The Unit - Rothenberger ALLGAS Mobile Pro Bedienungsanleitung

Check the tightness of the screw connections with foaming agents (e.g. leak detection spray
ROTEST, Art.-No. 65000).
Close the cartridge valves in case of an accident, or after use.
Depressurize the hoses after completing work by opening the valves on the handle while the
pressure reducers are closed, then close the valves on the handle again.
Do not use the unit in a horizontal position.
Keep the unit free from oil and grease. Oils and greases of all kinds can self-ignite explosively in
pure oxygen.

Function of the Unit

Welding with high-power welding tips:
Basically, the welding flame should burn neutral (the mixing ratio of gases is balanced), and its
size should be adjusted to the material thickness, the bead shape, the welding position and the
thermal conductivity of the material.
For welding steel with larger thickness both valves should be wide open and for welding of steel
sheets with low material thickness the valves should be turned back slightly.
Preheat material and welding rod. Once the metal begins to melt on both sides of the seam, add
the welding rod. Look for a uniform heating of the weld. Lead the burner in semi-circular move-
ments around the welding rod.
Brazing:
Deburr the joint surface and make it metallic bright (free of dirt and oxide), e.g. with the metal-
free ROVLIES cleaning pad (Art.-No. 45268). Preheat solder joint. Add the tip of the solder rod
on top of the solder joint, melt a drop of solder and spread it with constant movement of the
flame.
