• 3.4.3. The operation for the MIG GUN
1.
Service the wire feed mechanism at least every time the reel is changed.
-
Check the wear of the feed roll groove and change the feed roll when necessary.
-
Clean the welding gun wire guide with compressed air.
2. Cleaning the wire guide
Pressure of the feed rolls remove metal dust from the filler wire’s surface which then finds its way
to the wire guide. If the wire guide is not cleaned, it gradually clogs up and causes wire feed
malfunctions. Clean the wire guide in the following manner:
Remove the welding gun’s gas nozzle, contact tip and contact tip’s adapter.
With a pneumatic pistol, below compressed air through the wire guide.
Blow the wire feed mechanism and reel housing clean with compressed air.
Reattach the welding gun’s parts. Tighten the contact tip and contact tip’s adapter to spanner
tightness.
