Setting the shielding gas quantity

Electric shocks!
When setting the shielding gas quantity, high voltage ignition pulses or open circuit
voltage are applied at the welding torch; these can lead to electric shocks and burning
on contact.
• Keep the welding torch electrically insulated from persons, animals or equipment during the
setting procedure.
• Press the torch trigger and set the shielding gas quantity with the flow gauge of the pressure regulator.
Rule of thumb for the gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7mm gas nozzle corresponds to 7l/min gas flow.
Incorrect shielding gas setting!
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!
