4.1. DAILY MAINTENANCE
• Remove welding spatters from the welding gun’s tip and check the
condition of the parts. Change damaged parts to new ones immediately.
Only use original Kemppi spare parts.
• Check that the insulating tips of the welding gun’s neck are undamaged
and in place. Change damaged insulation parts to new ones immediately.
• Check the tightness of the welding gun’s and earthing cable’s connections.
• Check the condition of the supply voltage and welding cable and replace
faulty cables.
4.2. 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.
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.
