CNC torch vs Hand torch - RESOLVED

I bought the everlast ITP60 CNC torch to replace the handle one with trigger. I can’t get it to fire with the Crossfire. It did fire, very weakly at what seemed to be a very low voltage and only scared the metal and fizzeled out but the CNC kept going like it thought the torch was on. Any suggestions or configs I need to do with the new torch? It’s the first time cutting with the CNC torch. It is a 4 pin vs a 5 pin on the handled one, assuming that pin is the trigger. Everything worked fine before the swap.

I’ve checked the pierce delay and all the machine settings are normal. It kinda fires but doesn’t stay fired, and keeps going like its firing.

I am not familiar at all with your plasma cutter, but it seems you’re wanting an answer right away.

Has anything changed outside of replacing your torch? You didn’t accidentally put it in 4T right?

Did you leave all other items plugged in such as the torch on/off to the control box, VIM, etc? Just making sure you didn’t unplug something and accidentally left it loose or plugged it into the wrong slot.

Is everything else running as it should be IE enough air pressure, dry air, etc.

What actual troubleshooting have you done; this is in response to your “low voltage” remark.

Did you properly set your torch height?

Thanks for the response. Yes I’ve checked everything and it’s all normal as far as I can tell.

This error comes up . I’ve checked all the settings

In general, a Machine Torch requires more pressure than a hand held. What is your operating pressure? 60 PSI min is recommended.

It’s about 70

When I do the test fire it works, drills a hole but testing firing again doesn’t work. Moving the head and trying again it may or may not fire. The voltage appears to be very low as the spark is very light, not like it’s even firing fully. Amps was 40 on 16g steel.

Can you show a photo of how your torch is mounted? If mounted on the head, it could cause issues.

Do you have a machine torch mount? Where is the torch clamped?

If you clamp on the lower 3 inches of that torch, it will restrict the movement of the electrode and prevent.it from firing

I don’t know if this pertains to what is going on with yours but look at this link/thread from this post on:

Maybe that is the problem. I thought the torch was fairly big. Is this even installed correctly?

I just moved it

Make sure the electrode moves.

Electrode moves, I replaced it as well. Tip is new. Still no go

Did the torch fire test and it fired 2 out of three on the first test, then 1 out of three second test, then it would not fire at all.

Could it be a bad torch? I guess I’ll have to swap it back to the handle torch and contact Everlast

From what I have read it seams you are only getting pilot arc and not transferring to cutting arc. Pilot arc will read on the plasma cutter display at about 23 amps. I would be looking into were your work clamp is. The work clamp should always be on the metal being cut, not the slats, table or waterpan. Also turn off THC till you get the torch to cut.

Thanks @mechanic416 , I thought that as well. I clamped the work clamp directly onto the piece. Still did not work. I contacted Everlast and have a few troubleshooting steps. Then I’ll revert the torch to the handle with trigger, which I’m sure will work as it did before. I’ll update later today. I’ll try turning off THC as well. Good idea.

The machine torch should have 4 pins. 9 & 2 are the torch in place pins and the 4 & 7 pins are pilot arc. There are no trigger pins on a machine torch. If your still having trouble after talking with Everlast you can call me.

Everlast wanted me to jump in 1 and 2 on the back of the machine but I don’t see that. I switched back to the hand torch and unplugged the CNC controller on the back, unplugged from the vim box, switched the plasma cutter to unlock or not CNC, pulled the trigger and nothing. When I let go of the trigger the post air starts.

Looking at the machine it’s set at 42amp, when I pull the trigger it drops to 23amps but nothing happens, no air nothing. Then letting go of the trigger the post air starts

One and two are the top two. All Everlast Pierce starts at 23 amps. This is regardless of the setting.
Pin one and pin two are just a switch. When they are connected, the torch fires. No polarity.
Have confirmed that the CNC torch is not defective? I don’t see your work clamp in the video. Please show me a picture of the lights on the front of your machine. The one should be on CNC and the other on auto restart. Work clamp on the metal being cut is mandatory. Plus you are holding it way to far off the metal to initiate and arc. Actually place it on the metal and try.
One more thing you have confirmed that the electrode moves up and down with your finger inside the torch? The video shows the hand torch.
When using the hand torch trigger did you take the machine off CNC mode? The way you are testing the trigger needs to tripped at the CNC port. If the machine light says CNC.

Oh I thought that was a 12.

I completely removed the Langmuir hardware (CNC plug and vim box) and operated the plasma cutter as a stand alone machine. It wasn’t on CNC, just a regular hand held plasma cut method and it didn’t fire. The ground was on the work piece as well.

Everything worked fine a month ago, it just sat for a month with no use and now it doesn’t work.
