No live voltage

I have a pro table that was using an Everlast 50S with raw voltage in the VIM box.

I just upgraded to a Hypertherm 45XP with the Langmuir plug n play cable. I am NOT getting any reading on live voltage now so it stops running immediately because live voltage is lost with the THC. What could it be? What have I done wrong?

My voltage is also zero when I fire the torch on the material manually. I am not getting any voltage reading.

I’m an idiot. I got it. I am so dumb.

I did not move the RAW output to DIV output!!! That has to be it right. Dammit.

Yes that would definitely cause the issue. Did that fix it? Thanks!

Yes. I feel like an idiot. Stumped me for about 30 minutes. All of your support everywhere linked back to “you have to have it wired wrong” and as I looked at it again it clicked “you changed input. What about output?”

I vote to leave this up so if anyone else is as dumb as I am.

If you are having THC voltage issues I highly recommend going through our guide here: LS-THC Arc Voltage Troubleshooting Guide

Hey Everyone, Thought I would put it up on the forum see if anyone can help out. I am also seeing 0 live volts (See Pic) I can toggle control the THC unit manually. I have even gone as far back as to re-open the electrical enclosure to ensure the THC module is installed correctly. I am running a hypertherm 45Xp with machine torch with the plug and play cable ( Also Triple checked x 100 ) that cable is correct, ( Maybe still wrong ??)

If anyone could please help out, I am yet to make a cut on my X fire pro so i am as green as they come.!


did you get this fixed? having same problem

What problem are you having? The live voltage is supposed to be zero unless the torch is firing.

yes, it was a faulty unit, Langmuir replaced some parts for me. I cant remember what. The table is working very well now. Sorry I cant be more help.
