WARNING
ELECTRIC SHOCK can kill.
•Have an qualified person service this equipment.
•Disconnect input power by removing plug from receptacle before assem- bling or disassembling torch parts, or torch and lead assemblies.
•Do not touch electrically hot parts.
ROUTINE MAINTENANCE
1.Keep the cutting or gouging area and the area around the machine clean and free of combustible materials. No debris should be allowed to collect which could obstruct air flow to the machine.
2.Every
-Printed circuit boards and heat sinks
-Power switch
CAUTION
•When using a low pressure airstream, wear appropriate eye protection. Only use dry com- pressed air for cleaning. Do not point the jet of air at the electronic circuits.
3.Examine the sheet metal case for dents or break- age. Repair the case as required. Keep the case in good condition to insure that high voltage parts are protected and correct spacings are maintained. All external sheet metal screws must be in place to insure case strength and electrical ground continu- ity.
4.Inspect the cable periodically for any slits or punc- ture marks in the cable jacket. Replace if neces- sary. Check to make sure that nothing is crushing the cable and blocking the flow of air through the air tube inside. Also, check for kinks in the cable periodically and relieve any so as not to restrict the flow of air to the torch.
5.Inspect Torch Body and Handle, keep thoroughly clean WITHOUT THE USE OF SOLVENTS. In case of damage replace components for SAFETY CONDITIONS. If repairs cannot be made on site contact a local field service shop.

Shield Cup:
•Unscrew manually from the head of the torch. Clean thoroughly and replace if damaged (burns, distortions or cracks).
Nozzle:
•Check wear of plasma arc
Air Distribution Ring:
•Verify there are no burns or cracks and that air- flow holes are not obstructed. If damaged, replace immediately.
Electrode:
•Replace electrode when crater on emitting sur- face is about .08”(2mm).
WARNING
•Before making any adjustments to the torch, let it cool the entire
•Except for particular cases, it is advised to replace electrode and nozzle AT THE SAME TIME.
•Insure correct assembly order of torch parts.
•Be careful that gas distributor ring is assembled properly.
•Reassemble shield cup screwing it on manually (hand tighten)
•Never assemble shield cup without having included gas distributor ring and nozzle beforehand.
•Timely and appropriate maintenance on torch parts is essential for safety and proper functionality of the cutting system.
