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.
• Change damaged insulation parts to new ones immediately.
• Check the tightness of the welding gun's and earth return cable's connections.
• Check condition of mains and welding cables and replace damaged cables.
• See that there is enough space around the unit for ventilation.
Service the wire feed mechanism at least every time the spool is changed.
• Check the wear of the feed roll groove and change the feed roll when necessary.
• Carefully clean the welding gun wire liner with dry compressed air.
When using compressed air pistols, ensure you are wearing adequate safety equipment
NOTE!
including, suitable work clothing, gloves and eye protection. Never direct compressed air pistols or
the end of the liner at your skin, face or others in the vicinity.
Kempact RA models are fitted as standard with both over temperature and WireLine service

indicators (described earlier in the manual).
If the overheating indicator is displayed, this may be due to welding durations exceeding
the set duty cycle. The machine will reset after a cooling rest period. However, if the optional
cooling air intake filter is fitted to the machine, this may be contaminated, restricting cooling
airflow and require cleaning. See section 4.9.1.
If the WireLine service indicator is illuminated, this indicates that the wire delivery system is
not running efficiently. Checks, adjustment or cleaning is required to the spool hub friction
assembly, wire feed mechanism or gun/liner assembly. Welding is not prevented when the
WireLine service symbol is active, and is maintenance advice only.
