5.4 Controlling the shielding gas
Make sure that all shielding gas connections are airtight.
The nature and the quantity of shielding gas depends on the welding application and on the gas
nozzle type. Set in accordance with your welding procedure (WPS).
Loosen the drive rollers and cut the wire electrode flush with the gas nozzle using a cutter.
Slightly open the gas cylinder valve and push the torch trigger or the gas test button on your wire
feeder: shielding gas comes out. Place the flowmeter in a vertical position on the gas nozzle (Fig. 1)
and adjust the gas volume on the regulator.
Attention:
Poor gas protection leads to poor welding quality.
