Solutions
0-50-0 Retaining cap off (Test 8)
On On
• Verify that proper consumables and retaining
cap are installed. Replace damaged parts.
Refer to section Torch Setup.
• With the retaining cap installed, check for
continuity between pins 5 and 7 at the torch
connector.
• If the consumables appear to be installed
correctly, the torch may be damaged. Test
with a known working torch.
• After correcting the problem, perform a cold
restart.
0-51-0 Start/trigger signal on at
power up (Test 7)
This situation indicates that
the power supply is receiving
a start signal at power-up. It
is sometimes referred to as a
“stuck start.”
On On
If the power supply is turned on while the torch
trigger is pressed, the system is disabled.
• Release the trigger and cycle the power to
the machine.

7 of the torch connector. There should be
very low resistance when the torch trigger is
pulled.
• Test with a known working torch.

• Plug a torch lead into the FastConnect
receptacle on the front of the power supply
and recycle the power switch.
