Finally bit the bullet and bought a TIG welder

hahahaa...

Hey, I'm still screwing everything up, but that's why I wanted to post up here. In case I do, everyone can have a few laughs and hopefully not do what I did, when I botched something!

I'm extremely happy to find out that the pedal is just a fancy potentiometer.

I'm tempted to see if I can put a frequency generator in it for DC.

I didn't think about it, when I bought the welder, it has AC frequency and polarity balance, which drastically lowers temp and controls penetration, but not on DC for ferrous metals.

I was tripping the hand trigger quickly to try and taper the heat off at the end and I feel like if I can have frequency up around 60-120hz while I weld and use the foot pedal to taper in and out, I can have even more heat control/ focus on stuff like sheet metal.

If it can handle frequency on AC up to 200hz, I don't see why it couldn't handle it on DC. If I can, I'll see if I can make a frequency generator behind the pedal and sensitivity potentiometers and build it into the pedal.
