Looks like something I can fab..I have the wc torch mounted control, great for off bench welding. But a tad clumsly for dynamic power control..learned to use pulsed instead.

If that's what you did with "no electronics experience" I don't even know what I would classify as........

Very nice build and the knobs look awesome, I think your idea of putting most electronics in a seperate box is a good idea as you might get tired of reaching down and adjusting but then again, maybe not. Either way, looks great.
if there's a welder, there's a way

Think I will do the same, put the pot in a separate box and make it possible to use the torch switch without changing connectors.

Too often I change the max current while repositioning the pedal with my feet.

I'm doing something similar. Have been using a Weldcraft RCCS 14 for 5 years but now need foot pedal. The dial is actually a spur gear at around 13 teeth to the inch so I used a 1/2"x 13 UNC tap to thread the inside of a plastic pipe, then cut the pipe into strips to make a rack. Simple and fast.

Same kind of pedal but a pull-pull cable system to pull the rack. No mods to the RCCS 14

My first time replying to a thread on this forum so hope it works..

The pedal supplied with my machine had a 1k pot on the side that was supposed to limit the max amps but when I opened it to see why it didn't work I found it had no wires connected to it. It was only there for the sales brochure pic, lol.

I added and wired in a 25k linear pot to limit the range but found the knob on the pedal itself not very practical to use down there so I removed it and put it in its own box close to the machine.

I recently finished that mod, I also got a new cable with 5 wires in it, so now I only got one cable running from the pedal and the controls in a plywood box on the welder. Still a bit half-assed, not quite sure where I want to place it, but I am thinking of bending a bracket so I can just hook the box over the welder and it can hang on the side.

With the new CK17 torch and it's super-flex cable, it's a whole different ball game.

Definitely a great example of necessity being the mother of invention. I have found that most folks in this trade are smarter than the average bear anyway. Great job! :)

Thanks, though I am not in the trade, just a hobbyist who started in 2015 with an old used stick welder.

Hobbyist or not, it takes a bit of knowledge about a lot of things (metallurgy, thermal dynamics, electricity in general) to be a fairly competent welder. You may have picked it up as a hobby, but I bet you learned a few things about those subjects along the way. :)

Love your attitude, DennisCA, and great work. If you need it, build it! :-)

I want a pedal too, for my old MasterTig 3500W. I weld cast bronze, so it's hard to do without a pedal, due to the varying thickness and angles.

My question is: would you maybe share the diagram and especially the pinouts of the connectors with us? Our local Kemppi rep here in Malmö, Sweden is entirely unhelpful. He would rather I pay him to do the job, which doesn't really work for me!? Duh.
I have the same 4-pin and 10-pin connectors as you do.

Cheers,
A hack a day...
