5.8.2 Shielding gas supply (shielding gas cylinder to the welding machine)
No impurities must be allowed to enter the shielding gas supply as these could cause
blockages in the shielding gas supply.
•
Place shielding gas cylinder in the retainer provided for it and secure with chains.
•
Before connecting the pressure reducer to the gas cylinder, open the cylinder valve briefly to
blow out any dirt present.
•
Screw the pressure reducer onto the cylinder valve, ensuring a gas-tight connection.
•
Connect the pressure reducer to the G¼ shielding gas connection (F1) on the rear of the
machine.
•
Open gas cylinder valve and set recommended gas quantity on the pressure reducer.
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
