The workpiece surface is not
clean (paint, rust, oil, grease).
The shielding gas's solenoid
valve does not open.
The shielding gas volume is too
low.
The gas nozzle is dirty.
A mains phase is missing.

on page EN-24
► Clean the wire guide tube or wire
guide liner with compressed air and
replace the wire guide liner if
necessary.
► Clean the contact tip and replace if
necessary.
► Replace the welding wire.
► Insert the wire feed roller with a groove
so the latter is aligned with the wire
feed tube.
► Clean the surface.
► Check the solenoid valve and replace if
necessary.
► Adjust the shielding gas volume on the
pressure reducer.
► Use a gas flow meter to check the gas
duct for gas loss.
► Clean the gas nozzle.
► Check the mains fuse and power cable.
► Adjust the wire burn-back time.
► Adjust the wire feed speed.
► Let the system cool and restart the
welding process.
► Replace the filter.
