ROUTINE MAINTENANCE
WARNING
SHOCK HAZARD: Always turn off the power and unplug the cord before changing consumable
parts. Do not rely on the cap-on sensor switch to remove power. It is provided strictly for safety
backup. In the U.S., use a "lock-out / tag-out" procedure until the service or maintenance work is
complete. In other countries, follow appropriate national or local safety procedures.
Under severe conditions, routine maintenance should be performed more frequently.
Before Each Use
• Check the air pressure.
• Check the torch and consumables.
Every Week
• Check the torch cap-on sensor system by listening for the micro-switch to "click" when the retaining cap is
loosened. Check the
Torch Cap Shutdown System as follows:
Turn power On (I) and loosen the torch retaining cap.
If shutdown system works properly, READY LED extinguishes and TORCH CAP LED illuminates.
If the shutdown system does not work properly, turn power Off (O) and check for proper air pressure,
blocked or leaking hose, or loose torch retaining cap. Check the system by retightening the retaining cap
and resetting the power as described above.
3 Months

• Check the torch body and torch lead.
• Replace the torch lead if the insulation is broken.
