3.5 Shielding Gas Connection
Observe the standards (see appendix) when handling the
shielding gas bottles.
Connect the shielding gas bottle as follows:
Connect the gas hose of the shielding gas bottle to the gas inlet of the power
unit.
Connect the gas hose of the welding gun to the gas outlet.
Set the flow meter of the shielding gas bottle to 8 - 16 liters/min.

) is mainly used for stud
welding.
