Foot pedal issue/tweak.
In total noob mode here and was practicing on some 304 stainless pipe and some aluminum pipe, having a hard time getting a good puddle, etc. Well, finally it dawned on me that I wasn't getting the amperage I dialed in on the front panel.
Turns out the foot pedal "rail" that drives the cog on the potentiometer was not pivoting as it should, so would quickly lose contact with the cog and stopped working. The pair of nuts on the far end of the pivot screw needed to be loosened up a bit so the thing can pivot freely. Squirted a little lube on both sides of the rail while I was at it.
The other thing I noticed is the stop screw was really loose and woobly. It appears to be a standard M6 thread so I rummaged around for some nuts to put on top and bottom to stabilize it against the foot pedal housing. BIG improvement!
Hope this helps some other poor dumb bastard (like me) who finds themselves struggling with the foot pedal. Also, be sure to adjust the stop screw so the pedal doesn't go too far down and put too much stress on the potentiometer (when it reaches it's limit).
