Change damaged insulation parts to new ones immediately.
•
Check the tightness of the welding gun's and earth cable's connections.
•
Check the condition of the supply voltage and welding cable and replace faulty

MAINTENANCE OF THE WIRE FEED MECHANISM
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.
Cleaning the wire guide
Pressure of the feed rolls removes metal dust from the filler wire's surface which then finds its
way to the wire guide. If the wire guide is not clean, 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 though the wire guide.
3. Blow the wire feed mechanism and reel housing clean with compressed air.
