Figure 4.1. Parts of the welding gun and wire guide
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:
1. Remove the welding gun's gas nozzle, contact tip and contact tip's adapter.
2. With a pneumatic pistol, blow compressed air through the wire guide.
3. Blow the wire feed mechanism and reel housing clean with compressed air.
4. Reattach the welding gun's parts. Tighten the contact tip and contact tip's
adapter to spanner tightness.
