Operational description

Welding with high-performance welding nozzles:
Basically, the welding flame should burn neutrally (the gas mixture is balanced), and its size
should be adjusted to the material thickness, the weld shape, the welding position and the
heat conductivity of the material.
When welding steel at greater thicknesses, open both valves wide, and when welding thinner
welding steel plates close the valves somewhat.
Preheat the material and welding rod. As soon as the metal begins to melt on both sides of
the seam, introduce the welding rod. Make sure that the welding area heats evenly. Run the
burner in half circles around the welding rod.
Brazing:
Clean the connecting surfaces polish them and round off the edges. Preheat the brazing
area. Place the tip of the soldering rod onto the soldering area, melt a drop of solder, and
spread it under constant flame movement.
Torch cutting:
Select the torch cutting nozzles (23) according to the workpiece thickness (refer: technical
data) and then screw them until leaktight into the torch tip of the cutting attachment (20) or
hand held cutting torch (15).
Using a suitable wrench tighten firmly the nozzle retaining nut in the torch tip. Use clean,
undamaged ROTHENBERGER original torch cutting nozzles only. Make sure that the sealing
surfaces on the nozzles and torch tip are in perfect condition.
Adjusting the operating pressures
First, keep the adjustment valves for oxygen and fuel gas (16 and 17) on the handle or hand-
held cutting torch closed.
Slowly open the cylinder valves (1 and 2) or the tapping point valves in the distribution line (9
and 10).
