Review on Welder Control Digital Display Controller Industrial Power & Hand Tools by James Womble

I would love if this unit came with stands so you can mount two boards at the same time. You must use an AC power supply for the motherboard. which is easy. Pry each wart on the 12 volt DC wall along the seam, remove all electronics and rip the transformer straight off. The device gives a pulse to the welding transformer to reduce the spot welding power. This works best if you have a heavy duty 20 amp circuit breaker feeding your system. The transformer ripple at full load creates a lot of noise in the electrical system. So work as close to the mains as possible, if possible in a garage 10 feet away. overall a great unit.
