 If yes, continue with the next step.
 If no, continue with step 5.
3. Disconnect the torch from the plasma power supply.
4. Make sure that the torch trigger is not being
pulled, and measure the resistance between
pin 6 and pin 7 in the torch connector. Is the
resistance very low?
 If yes, do a check for short circuits in the
torch lead. Replace the torch lead if the
wires in it are short-circuited.
 Also do a check for short circuits in the
trigger switch assembly. Replace the

6. Measure the resistance between pin 6 and pin 7 in the torch connector while you are pulling the
torch trigger. Is the resistance very high?

circuits.
