I received my foot pedal yesterday, getting ready to head out and give it a go.

Well, no dice using the foot pedal. I kinda figured that would be the case, but there are crazier things that have happened. I guess I will be testing SCRs and SDRs next.

Anyone know an easy way to test them with a DMM?

Also, there is a shunt on the ground lead inside the unit, any chance a shunt would cause this? It looks like it's gotten HOT.

ran across this https://www.youtube.com/watch?v=nYP-DfLI1G4 not sure it will work on yours.

Unplug machine, make sure caps are discharged and look for loose connections. Hot/cold cycles can sometimes do it. That blued connection may be loose: ie: high resistance.

YES.

I have read that often ground links on import machine can be very thin. This is not the case on the one I bought, but on certain well-known eBay or Harbor Fright jobs it is recommended to add additional internal ground straps to avoid problems at high output.

I didn't study anybody's circuitry to see why this might be so, but I saw multiple reports of this issue when I started welder shopping, some years back.

I'd add some copper there and see if it cooks.
