So new to the cnc plasma table world, i have a razorweld 45 with a crossfire pro. Brand new setup, made probably 3 or 4 perfect cuts, then the torch started turning on and off multiple times during the part. Doesnt throw any errors and the table finishes the run, just the torch turns on and off multiple times during the run. Heres what I’ve tried:

THC on and off

As dry of air as i can do at the moment(moisture trap/filter, then desiccant dryer, then regulator/filter/moisture trap)

Different cut speeds/pierce delays/amps

Grounded directly to work

New consumables

Ample air pressure, have adjusted the regulator in the machine from 60-85 psi, regulator on shop air is set at 110

Cutting in 2T

Outlet is wired for 60amp with 6awg wire

Tried the “straight cut” program in firecontrol thinking it was an issue with my programs from fusion, still did it

Machine torch is clamped correctly on the “barrel” above the plastic

I will say I accidentally left it on 4T for my first several cuts(noob me didnt read the manual first), and it actually was some of my better cuts so far, but switched to 2T when it started having this issue and it actually does it far worse on 2T(hopefully i didnt mess something up cutting in 4T?)

I did notice at one point the torch quit firing when the machine was being told to, did a thc test and it wouldnt fire, wiggled the connector on the front for torch fire and it started working again, took the torch fire cable that comes with the kit with the scotch locks and bypassed the connector with that cable, torch is firing but still doing the same thing with cutting on and off
Idk im at a loss, if anyone can help thatd be great

@Blaisehudson Welcome to the forum

The picture you show has the torch incorrectly mounted.

I find it wierd that with the THC on with the torch turning on and off while it should be cutting is not throwing an error.

Have you successfully cut a part with the cut file you are using?

Air pressure dropping during the cut combined with a sticky plugin from clamping pressure maybe an issues?

When you get the ability to you could post the cut file and we could look it over for errors.

edit: I see you change the mount position in the second picture

I think a video would be best. This is definitely odd. I was going to wager accidentally setting up huge tabs in the design phase until I read it did it on a firecontrol generated straight cut.

If he’s running the razorweld torch, I’m not sure it’s incorrectly mounted. That razorweld torch copies the hypertherm right? I thought It’s the ipt60 or whatever that has to be mounted differently.

I think that this here is your problem child.

Check all the connections inside the plasma, Check the crimps on the wires, check the cable, check all the connections at the control box.

You did a wiggle test, now you have to find where the bad connection is. You may have more than one bad point.

Did you open up the control box and make sure that the torch fire relay is fully seated?

That torch has moving parts in the torch head and should be clamped on the barrel. Also ALL machine torch’s are designed to be mounted on the barrel. You can get by with mounting the newer (not SYNC) Hypertherm and its copy’s by mounting it closer to the bottom as it does not have moving parts in the head. I would also recommend that you do not mount the new Hypertherm SYNC torch’s on the torch head as they have electronics and sensors in it.

I see. So like this for the x45 torch?

Hey there! Please take a moment to appreciate this awesome illustration. I think it’s been shared over a hundred times! It’s so cool that it should definitely be on the cover page of every Langmuir plasma table.

Haha. I never realized, until this second that image was of the x45. Wow…. I’ll go to my corner now. Lol.

No, the copyright belongs to @mechanic416 George. I keep it on my hard drive and phone for quick use. :wink: He may get a dollar or so every time we use it. He can probably buy a new Ford soon with the royalties.

So I forgot on some of these pictures i did have it mounted incorrectly and have since corrected the issue, and have taken the torch head apart to ensure i didnt cause damage to anything

Yes i had it clamped that way prior to seeing these pictures posted on other forums and have since corrected the issue

Send a dollar to @mechanic416. Haha :joy:
Glad it went well. Sorry, I don’t follow the Facebook forum. Some of us are not allowed or want to.

Still having the cutting issue however. Ive taken the torch head apart to ensure I hadnt caused damage and everything looks good. There was 2 tiny wires in the torch head that have never been crimped together, assuming theyre not supposed to be? 2 go to contacts that contact the insulator, 2 coming through the loom to the torch head(blue and yellow)

I believe those are the only wires required for the torch to fire. The other wires were for the trigger that’s not used.

Like @brownfox said, please send us a video of the machine cutting. Also, make sure you have the machine on 2T, not 4 T. Additionally, draw a simple square or circle in fusion and try cutting that.

Air pressure staying steady, I have cut a couple parts successfully off of the cut files I’m trying, however it also does this when using the “straigh cut” file on firecontrol

Ill have to get a video in a bit. Its in 2T, and does it when cutting a staight line in firecontrol as well
