• Tighten the pressure regulator screw connection on the gas bottle valve to be gas-tight.
• Screw the shielding gas connection of the welding torch to the pressure reducer on the shielding gas
cylinder.
Slowly open the gas cylinder valve.
•
• Open the rotating valve on the welding torch
Before each welding process, the rotating valve must be opened; after the welding process, it
must be closed.
Set the required amount of shielding gas on the pressure reducer, about 4 - 15 l/min depending on the
•
current strength and the material.
Rule of thumb for gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7 mm gas nozzle corresponds to 7 l/min gas flow
