4. MAINTENANCE
Watch out for mains voltage when handling electric cables!
In planning product maintenance machine utilization degree and circumstances should be considered.
Careful use and preventive maintenance help to avoid unnecessary production disturbances and
breaks.
4.1. DAILY MAINTENANCE
The following maintenance operations should be carried out daily:
 Clean the wire channel and check contact tip. Replace defect parts.
 Check the mains and welding cables always before operation. Replace defect cables.
4.2. REGULAR MAINTENANCE
4.2.1. Every sixth months
The following maintenance operations should be carried out at least every sixth month:
 Check the feed roll grooves for wear. Replace worn out parts. Excessive wear of grooves
causes problems in wire feed.
 Check wire guide tubes for wear. Replace worn out parts.
 Check that the wire line is straight. The wire guide tube in the gun should be set as near the
feed rolls as possible, but not touch them. Also check that the wire is in straight line from
the end of the tube to the feed roll grooves.
 Check the wire reel pressure. Adjust if necessary.
 Check electric connections. Tighten if necessary and clean oxidized surfaces.
 Clean the equipment housing and power source filter. The filter can be cleaned with
pressurized air or washed, if necessary.
4.2.2. Service contract
KEMPPI –service workshops make special service contracts with customers about regular
maintenance. All parts are cleaned, checked and if necessary, repaired. Also the operation of
welding machine is tested.
