I just started installing the THC and I’m using the Primeweld Cut 60. I can’t figure out how to wire the VIM into the CNC port in the back of the machine. Would anyone be willing to give me guidance on how to do this? this is the adapter that came with the cutter but I can’t figure out how to attach the wires to pin 4 & 6. Thanks for your help! Gary
You solder the wires to the pins. 1 and 2 for the trigger and 4 and 6 for the divider.

Thanks for the info. I see the 4 & 6 pins are for the THC but I haven’t seen anything about pins 1 & 2 for the trigger. Am I just missing something? Thanks

Yes, you have to have trigger wires or it won’t fire.

I followed the directions for wiring the torch to the inside of the machine (like in the pic). Do I need to remove from inside the machine and solder to the CNC pins in the back? Thanks
Instructions: Locate the torch firing cable that was provided with your machine and connect the blade connectors to the T-Tap connectors.
It does not matter which blade connector gets plugged into which T-tap connector. The polarity and wire coloring is not important.

NO you do NOT wire anything to the inside of the plasma cutter. It all gets wired to the CNC plug ONLY.

I really appreciate you taking the time to help me. What you’re saying makes sense but it makes me wonder why the instructions go into detail about splicing the wires and using the furnished wire connectors. I would prefer to use the CNC pins so I guess I need to disconnect the splice connectors, cut the connector ends off, and solder the wires to pins 1 & 2? Thanks again mechanic416! As you can tell I’m very new at this.

technically he can but not necessary since the CUT60 has the CNC port.
GCJUBY:
here’s how i connected mine to the CNC port. The top 2 pins are 1 & 2 to fire the torch. Wire color doesn’t matter as long as it’s those 2 pins. I would also add heat shrink on the ends or at least electrical tape on the ends to prevent shorting.

the instructions provided by Langmuir are for cutters that don’t have a CNC port.

Thank you nicaDd! It makes sense. I assume you simply cut the ends off in order to solder to the CNC pins?

“Technically” if he opens up the plasma cutter he voids his warranty. Then if he hooks it to the wrong wires, say the pilot arc wires and burns something up hes on his own.

Yes, you just cut the ends off and solder them to pins 1 and 2 for the trigger.

yes. I don’t remember mine coming with the end connectors attached.
what i did was dip the bare ends in flux, coat them with solder then inserted the soldered ends into the cnc pins and heated it up again with the iron so the solder can fill the pin holes.

true, BUT for non CNC cutters, that’s the only way to attached the wires…
Yes it is and if you cause something to burn out of blow a pc board then your on your own as they don’t have to warranty it no matter whom makes the plasma cutter. You should always ask the manufacture how to and if its ok before doing it.
As I do a lot of warranty repair work, if I see someone has been in the unit I stop and contact the manufacture to see how to proceed from their.
Hello …wondering if anyone can tell me what color wire goes to pin 4 on the CNC plug …is it the red or black from the THC pigtail …thanks in advance
Pin #4 is negative so I would guess the black wire, but I don’t know what Langmuir wiring manual for the THC tells you.

Just a note here. The Primeweld cut 60 1/50 pins 4 and 6 should read between 1.76 and 2.08 volts for the THC.

George , thank you for the feedback …just FYI for others that have a primeweld cut 60 and are hooking up the THC …Red wire will go to pin 4 as it’s the negative and black wire to pin 6 . Again thank you for the help .
