Manual 0-2470
Disconnect primary power to the system before disassembling
the torch, leads, or power supply.
DO NOT touch any internal torch parts while the AC indicator
light on the front panel of the power supply is lit.
1. Remove the shield cup, tip, gas distributor, and electrode
from the torch. Disconnect the torch leads from the power
supply to isolate the torch from power supply circuits.
2. Using an ohmmeter (set to 10K or higher), check for continu-
ity between the positive and negative torch quick disconnect
fittings. Infinite resistance (no continuity) should be found.
3. If there is continuity between the two torch quick disconnect
fittings, remove the torch head from the leads (see Servicing
Torch Head Components, page 47). Visually check that the
PIP wires, torch switch wires, pilot lead connection, and
negative/plasma lead connections are properly connected
and in good condition (no shorts or arcing). If problems are
evident, repair or replace as required.
4. With the torch head disconnected from the leads, measure the
resistance between negative cathode body of the torch head
(where the electrode seats) and the positive anode body of the
torch head (the outer threads where the shield cup seats).
Infinite resistance (no continuity) should be measured be-
tween negative and positive sections of the torch head. If any
current can flow through the center insulator, the torch head
is faulty and must be replaced. If the torch head is okay, the
problem is in the leads or quick disconnect assembly.
5. Slide the quick disconnect body, boot, and retaining ring back
(see Servicing Torch Leads Components, page 53). Visually
inspect the quick disconnect components to verify that there
is no contact between the positive and negative sections. If
contact is evident, repair or replace as required. If no prob-
lems are evident, remove the quick disconnect assembly from
the torch leads and check for continuity between the positive
and negative torch quick disconnect fittings. If there is no
continuity, the quick disconnect assembly is okay. If continu-
ity is found, replace the torch quick disconnect assembly.
