I have a Hypertherm plasma cutter with Pac130 torch. It was working when I bought it a few years ago.
Now it does not work, specifically, it does work, but starts an arc INSIDE the torch and burns the torch, instead of starting the arc and burning through the work.
I do have ground connected. Any idea what may be wrong?
Thanks
Call Hypertherm, (866) 956-2766, and ask.
I replaced them. The cutter cut well for a SHORT while and then burned the new components.

Water vapor in your air supply?
Best Regards Tom.
I have no experience with these things, but you have to have the air supply working. Any possibility there is an air leak, like a loose fitting or broken hose inside the hose/wire bundle?
I think the arc normally forms inside the torch head, and depends on the air to blow the arc out of the torch.
