5 – Troubleshooting and System Tests
Torch cap LED faults
The torch cap LED illuminates while the machine is powered ON.
Possible causes Possible solutions
 The cap-sensing circuit is open due to:
 The consumables are loose,
incorrectly installed, or missing.
OR
 The cap-sensor switch, torch
lead, or torch body is faulty.
 Make sure the consumables are installed
correctly.
 Perform Test 7 – torch cap-sensor on
page 89.
The torch cap LED blinks while the machine is powered ON.
Possible causes Possible solutions
 The consumables are stuck in an open or
closed position because they are installed
incorrectly, worn, or damaged.
 The nozzle and electrode are not touching
when the torch trigger is pulled. The torch
plunger is stuck.
 The torch or torch lead has a broken or
short-circuited wire.
 Inspect the torch lead. If it is twisted or
kinked, straighten it out and try to fire the
torch again.
 Make sure the consumables are installed
correctly. See
Step 1 – Install the
consumables on page 43.
 Inspect the consumables for wear, and
replace if necessary. Always replace the
nozzle and electrode together.
 Perform Test 5 – torch stuck open or torch
stuck closed on page 85.
The internal compressor, temperature, and
power ON LEDs blink, and the torch cap LED
illuminates.
Possible causes Possible solutions
 The torch was repeatedly fired with worn out
consumables.
 The inverter is saturated (is in an
over-current condition).
 Install new consumables in the torch (they
may be corroded or approaching end of life).
 If you continue to see this error, replace the
power board. See
Replace the power board
on page 126.
