5.1  TIG welding 

5.1.1  Setting the shielding gas volume (gas test)/rinse hose package 

•  Slowly open the gas cylinder valve. 
•  Open the pressure regulator. 
•  Switch on the power source at the main switch. 
•  Set the relevant gas quantity for the application on the pressure regulator. 
•  Press the push-button Gas test / flush hose package   to activate the gas test. 
Setting the shielding gas quantity (gas test) 
•  Shielding gas flows for 20 s or until the push-button is pressed again. 
Purging long hose packages (purging) 
•  Press push-button for about 5 s. •  Shielding gas flows for approx. 5 min. or until the push-button is 

pressed again. 

If the shielding gas setting is too low or too high, this can introduce air to the weld pool and may cause 

pores to form. Adjust the shielding gas quantity to suit the welding task! 

Setting instructions 

 

Welding process 

Recommended shielding gas quantity 

MAG welding 

Wire diameter x 11.5 = l/min 

MIG brazing 

Wire diameter x 11.5 = l/min 

MIG welding (aluminium) 

Wire diameter x 13.5 = l/min (100 % argon) 

TIG 

Gas nozzle diameter in mm corresponds to l/min gas throughput 

 

Helium-rich gas mixtures require a higher gas volume! 

The table below can be used to correct the gas volume calculated where necessary:

For connecting the shielding gas supply and handling the shielding gas cylinder refer to the 

power source operating instructions. 

 

5.1.1.1  Automatic gas post-flow 

If the function is active, the gas post-flow time is defined by the machine control unit in dependence on 

power output. Example: With the automatic gas post-flow function enabled, a gas post-flow time of 10 s 

has been set. This means that with a welding current of 230 A, the gas post-flow time is 10 s. At a weld-

ing current of 115 A, the gas post-flow time is reduced to 5 s. The switched on function will be indicated in 

the function sequence with “auto”. 
The defined gas post-flow time can also be individually adjusted if required. This value is then saved for 

the current welding task.
