General Regular preventive maintenance of the welding torch is essential for problem-free opera-
tion. The welding torch is subjected to high temperatures. It therefore requires more fre-
quent maintenance than other components in the welding system.
At every start-up - Check welding torch, hosepack and power connections for signs of damage
- Check gas and water connections for leaks
- Check that the cooling unit is working properly, monitor the water return level in the
coolant container, vent the cooling unit if necessary
- Check that the wearing parts are in perfect condition, clean wearing parts before fit-
ting them
Monthly - If applicable, check the filter in the cooling circuit for contamination
- Check that coolant is pure; if there are any impurities, replace the coolant and rinse
the welding torch thoroughly several times by letting coolant flow into it and back out
again
- Dismantle the welding torch and check for deposits/contamination
Disposal Dispose of in accordance with the applicable national and local regulations.
