I would imagine adding this wire for pilot arc would decrease the cutting thickness of the machine. When the machine is cutting , some of the power will be going back through that wire. You would have to hook up a relay or something to disconnect the pilot wire when cutting.
If it's 0-10v to the controller use a potentiometer. These are cheap convertor boards also if it needs pwm

I have a Clarke 160en transformer and an uptime mig 160. I still have the Clarke as I have it setup for a spool gun. The Clarke will probably out last me while the uptime is cheap and welds a lot better than the clarke. It could blow up if I look at it the wrong way.
Those 5 people should maybe invest a little more time on research lol. There are millions of people including myself happy with creality printers. I print pla, petg, TPU , nylon, Carbon fibre. My cr10 is modded, but it's a hobby and why I changed things. Creality printers work absolutely fine...
What material is on the bed? The newer printers bed material should be ok for PLA and PET. I switched mine to an IKEA mirror a few years ago and works great. I have another printer with a PEI sheet on it and it works ok. Prefer the mirror and glue stick.
The Prusa will have failed prints aswell. It's not the printer. You have to invest a little time and figure out how it works. First thing is make sure the bed is leveled. Clean the bed with water and then wipe it down with alcohol. Set your z offset. Run bed leveling before the print and try again
So you are able to use a cheap HF start plasma cutter with this THC. It can touch, start the arc, adjust, and maintain the height ? No need for pilot arc ?
Front lense looks generic enough , should be able to get one off AliExpress. Mine is flat , not curved . The way it's in there forces a slight curve when installed
If you are going to the trouble of a retrofit id go with Linuxcnc rather than Mach3. Depending on age and if you know what you are doing you may be able to reuse the existing steppers, sensors etc. Mesa boards would be the board to go for if going Linuxcnc but they seem scarce due to the global...
