3.2 Operational description and start up
Welding with high-performance welding nozzles:
Basically, the welding flame should burn neutrally (the gas mixture is balanced, see 4.1), 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 cutting nozzles (23) according to the thickness of the workpiece (see Technical
Data) and screw into the wing lever cutting insert (20). Now also screw the heating nozzle
(24) into the wing lever cutting insert (20). Now connect up this unit with the hand grip (15).
 To do this use a suitable installation wrench. Only use clean, undamaged original
ROTHENBERGER cutting nozzles. Ensure that the sealing surfaces on the nozzles and the
cutting head are perfect.
Adjusting the operating pressures
 Initially keep the adjusting valves for oxygen and fuel gas (16 and 17) closed on the hand
grip (15).
 Slowly open the bottle valves (1 and 2) or the removal valves (9 and 10) on the distribution
line by turning them to the left.
 Open the shutoff valve (7) on the oxygen pressure regulator and the adjusting valve for oxy-
gen (16) on the hand grip (15) by turning to the left and also open the cutting oxygen wing
lever (22) through tipping to the left.
 Adjust the operating pressure (see Technical Data) through turning the adjusting screw (5)
on the bottle pressure reducer for oxygen (3).
 Close the cutting oxygen wing lever (22) by tipping it to the right and close the adjusting
valve for oxygen (16) by turning it to the right.
 Open the shutoff valve (8) on the fuel gas pressure regulator and adjust the fuel gas pres-
sure (see Technical Data) through turning the adjusting screw (6).
Ignition and adjustment of the flame
 Before igniting, make sure that the connections between the containers and the regulator
valves have no gas leaks (use a leak location spray or soapy water).
