Smiley MTC120 Part help
 

Blast from the past. I got a Smiley MTC120 TIG welder / Plasma cutter sitting in the garage that was a hot item on this forum back in 2005 ;)

At some point, i tried converting it to a pedal but didn't finish and abandoned whatever i needed the welder for. It ended up sitting for the past 15 years in the garage and now I'm trying to clean stuff out and maybe sell it.. problem is it's missing the heat control potentiometer/knob. Anyone have a Smiley/mitech/whatever MTC120 and can take a pic or specs of the pot and where it plugs in, or better yet have a broken one and can sell me the potentiometer and handle?
