Works great after rewired for 220 VAC
I changed internal voltage selection circuit board connections to place the dual winding primary of transformer in series. Simple, scrape all the silicone junk off the board, move the wires to the outside pads. Solder a jumper in the middle of the board. Changed power cord to 220 VAC Air Conditioner type using a 20 foot grow light power cord (cut off IEC computer-type plug), soldered new cable directly into welder. Wow this thing welded a .2 mm nickel plated steel strip to the bottom of a standard (run down) D cell. Did not fall off and was unable to pull off the battery. That was with power set at 99% (maximum level), and two pulses. I didn't hear one good thing about running on 110 VAC. Since I have 220 VAC at 20 amps available for my ham radio linear amplifier inside my house it made sense. It would be possible to use a 220 VAC dryer outlet as an alternative. Our standard house wiring at 110 VAC just can't handle the surge current required for spot welding. With modification, I can whole heartedly recommend this unit.
