If I’m looking at everything correctly It seems like I can wire my ptm60 torch two ways… Well three, but tapping into the machine seems silly if I can avoid it.
One is to solder the langmuir provided leads to pins 1 and 2 on the cnc port on my cut60 plasma.
The second choice is to solder the langmuir leads to the two wires on the back of the torch.
I’d rather use the second option because I have already soldered and heat shinked the 4 and 6 pins on the cnc port to the thc and for an armature at soldering there is not much room back there.
But I’m new to all this and wanted to check the collective wisdom here on the board. Any disadvantages to either one or for that matter am I even correct in the possible wiring choices lol.
Thanks guys.
Nobody… not even a friendly " your an idiot, read this link and you will figure it out "
I think it would be helpful if you noted the type of plasma machine you have in the thread title so people with the same one can see their help is needed.

I am curious to figure out how to wire the same torch. I have a Prime weld Cut60 and wired the CNC port to the Crossfire Pro and the hand torch works fine. Upgraded to a PTM-60 machine torch and the air kicks on bit no Arc. The PRM -60 only has two pins as opposed to the hand torch which has four. I have a call into Prime weld but their offices are closed for Veterans Day.
Did you ever get an answer to this question???
You only have 2 pins #1 and #9 on a machine torch for the Primeweld. Their are no trigger wires on a machine torch. You need to wire the cable to pins 1 and 2 on the cnc port for the torch to fire.
Next you need a little more air pressure with the machine torch. 65psi flowing from the torch less then that it may not fire.
