consumables. Check and replace if necessary.
·
Input air must be clean and dry.
·
Input air pressure must be between 65 - 75 psig.

Work cable and clamp must be in good condition
and must make a good electrical connection to the
material to be cut.

If above items check OK , the problem is internal.
Send unit to an Authorized Repair Station for repair.

Missing or weak pilot arc. Check pilot arc fuse,
open circuit voltage, pilot arc resistors and pilot arc
wiring.
