Use YesWelder CUT-55DS PRO (no CNC port) or buy a new CNC-ready plasma cutter?

Hey everyone,

I’m currently setting up my CrossFire Pro and just picked up the THC as well. I already own a YesWelder CUT-55DS PRO, so I’m trying to decide if it’s worth integrating or if I should just upgrade to a CNC-ready plasma cutter.

From what I understand so far, this unit doesn’t have a dedicated CNC port, so I’d have to open it up and tap into the internal wiring for:

  • Torch on/off (trigger wires)

  • Raw arc voltage for THC

Before I go down that route, I wanted to ask:

  1. Has anyone here successfully wired up the YesWelder CUT-55DS PRO for use with the CrossFire (especially with THC)?

  2. How reliable has it been long-term (arc stability, THC performance, noise issues, etc.)?

  3. Would you recommend sticking with it, or is upgrading to something like an Everlast or Razorweld CNC unit the better move?

  4. Machines I’m considering are Titanium 45, Razorcut45 with machine torch. But I’m open to other options that don’t break the bank. i dont plan on cutting anything thicker than 3/8th

I don’t mind spending money on a better machine if it’s going to save headaches and give better cut quality, especially since I plan to use this for consistent work. Just trying to avoid unnecessary upgrades if this unit can be made to work well.

Any advice, wiring tips, or lessons learned would be appreciated.

Thanks!

I would suggest you try searching the forum for the answers to your questions as they have been talked about many times on here.

yeah i looked but i only saw 3 posts of people hating on chinese plasma cutters, nothing on the Yeswelder wiring so I’m leaning towards just buying a razorcut

It looks like a high frequency start machine, just by looking at the connections on the front of the machine. If that’s the case, it can’t be used on a Langmuir table.

You can use your YesWelder machine as long as you aren’t shy opening it up to hook it up. Looking at the specs online it is NOT a HF start machine which is the only hard rule on compatibility. The feeds and speeds sheet is kinda pathetic so you will be on your own dialing it in. You could probably use the Primeweld cut chart to get you close. The PW Cut 60 is a 6240 Watt (60A * 104V) machine and the yeswelder 50DS is a 5610 Watt(55A * 102V) machine. Point being their output voltage is similar (102 vs 104) so the PW chart should get you close.

There have been a few people that have considered that machine but I don’t know of any users currently using that machine. Here is a topic that discusses it.

YesWelder CUT-55DS Non-HF Plasma Cutter Candidate? - CrossFire ® / General Discussion - Langmuir Systems Forum
I think I saw a YouTube video of Mike Festiva trying a Yeswelder cutter on a CF Pro table. If I recall correctly his review was positive. I don’t remember what model he was using… and after a brief search I couldn’t find it on his Youtube page.

Snip from Cut-55DS spec

I included a snip of cut sheet provided by Yeswelder below. I converted the units to inches and inches per min to compare(snip of spreadsheet below cut chart). Honestly this cut chart really doesn’t make sense. I did some interpolation to complete the chart based on the graph, but the speeds dive off faster than they should when considering the wattage, the specs say the cutter produces. That’s why I say you may be on your own as far as feeds and speeds go.

Example of why the cut chart seems off.

YesWelder cut speed for 6mm(.24 in) 15.7 ipm @ 55 amps

PW Cut 60 cut speed for 1/4" 38ipm @ 45 amps

Nice compilation of info Erik!!!

@jeeter, Welcome to the forum. I hope you don’t mind that I shortened your topic title.
