5_SERVICE AND MAINTENANCE
INSTRUCTIONS
Specific torches instructions:
- Clean the torch nozzle adhered projections to avoid cut
circuits and gas turbulences. Use a steel brush.
- Avoid projections adherences, using a specific silicone-free
spray
- Periodically check the pinch rollers and breaking reel
- Verify the wire properly goes through
- Control the calibrated contact tip and replace it when
necessary in order to avoid wire contact loss with the nozzle
Do not use the torch as a hammer to eliminate welding dirt or
to align sheets.
