I picked up an Esab PCM 875 the other day and have been trying to get it working. The fault light is blinking the “Hi/Low input voltage” code. I got the plas to turn on and cut for a second during one of my tests. I stopped it but now the fault light is blinking again. Can someone help me? I don’t know what to do or what to check. Thank you

Searching the internet is often a good way to start.

You wouldn't have been able to find it, but at the bottom is a thread from this site about the predecessor machine. That was originally the L-Tec PCM-VPI, and good, cheap consumables are readily available on Ebay. It uses the PT-31XL torch.

The ESAB manual is currently available for downloading here; It has the circuitry schematic, and probably a troubleshooting area too:

Here's the old thread:
