Transport And Storage; Set-Up - Rothenberger ROXY 400L Instructions D'utilisation

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.

Transport and storage

For transport, the oxygen tank valve and the Maxi gas cartridge must be closed.
After finishing the soldering work: With the gas cartridge valve and oxygen tank
valve closed, cut off the gas and oxygen valve at the handle, and allow the remain-
ing gas to escape. This discharges the hoses and the oxygen pressure regulator.
Remove the oxygen pressure regulator. Screw off the gas cartridge valve of the
Maxi gas cartridge. The hoses can be connected to the oxygen pressure regulator
and the gas cartridge valve. Secure the device against tilting and slipping on the
loading surface. Store and transport only with the containers upright. Reusable
containers must be filled only by authorized facilities. Refilling in an unintended
manner can cause severe accidents.

Set-up

Change the gas cartridges in a well-ventilated area, preferably outdoors.
- Make sure that all valves are closed before work begins.
- During set-up, turn the oxygen pressure regulator tight with the wrench.
- Screw the MAXIGAS one-way container rightward into the gas fine regulator valve. Make
sure that the tread begins and moves correctly. Screwing it in on a slant voids the warranty.
- Before igniting, make sure that the connections between the containers and the regulator.
valves have no gas leaks. (Use leak detection spray or soapy water).
A Open the oxygen tank valve.
B Depending on the nozzle and the material thickness, adjust the working pressure to a
setting of up to 0,7 - 3 bar.
C Opening the oxygen pressure regulator valve.
D Now opens the gas regulator valve about a half turn.
E Opening the oxygen valve hand dial and adding oxygen.
F Open the fuel gas valve dial and light the gas flame.
G Setting the gas flame. The flame must already be burning visibly from the nozzle tip.
H Adjust the heating flame by opening or choking the gas and oxygen feed.
- See 5.2
I Use only goggles that comply with DIN4646 and 58210/1.
All connections must be tightened or loosen using the wrench included.
After the gas valve has been opened, ignition must occur immediately, be-
cause otherwise escaping gases can detonate.
Using the micro burner:
- Next unscrew the flame tube with the swivel nut.
- Then screw the micro nozzle adaptor directly to the torch handle using the swivel nut.
- Attach the desired micro burner, and screw the safety adaptor onto the micro nozzle
adaptor to secure it from coming off.
- Set the flame as needed. Beware of an extremely short fuel gas flame that already burns
visibly at the nozzle tip.
