Maintenance - Kemppi Flexlite GX Series Operating Manual

5. MAINTENANCE

When planning routine maintenance, consider the operating frequency of the welding equipment and the working
environment.
Correct operation of the welding equipment and regular maintenance helps you avoid unnecessary downtime and
equipment failure. Mainly due to the high temperatures, MIG guns require regular checks and maintenance. Peri-
odically, check the cables set for damage and ensure connections are tightened correctly.
Daily maintenance
Disconnect the power source from the mains power supply before handling electrical cables.
• Check regularly that all the components are tightly fastened.
• Check that the current transfer surface on the Kemppi gun adapter is clean and unscratched, and the connector
pins are straight and undamaged.
• Check the protective hose on the cable for damage.
• Check the two O-rings between the neck and the handle for wear and damage.
• Check the O-rings in the welding gun gas connector for wear and damage.
Only the gas-cooled gun has the O-rings.
• Clean dust from the liner with pressurized air every time you change the wire spool, or every day during heavy
use.
• Check and remove any spatter build-up from the nozzle.
• When not using the gun, keep it in the welding gun holder on the wire feeder.
For repairs, contact your Kemppi dealer.
Periodic maintenance
Only qualified service personnel are allowed to carry out periodic maintenance.
Check the electrical connectors of the unit at least every six months. Clean oxidized parts and tighten loose con-
nectors.
Use the correct tension torque when fastening loose parts.
Do not use pressure washing devices.
