Commercial welders are sometimes very cheap these days. In light of the many outlets that they can be purchased for a significant savings off the new msrp, I can see why many of you DIY guys aren't building any of these things from scratch.....but,
I was bitten by the bug and decided to look for circuit diagrams to build one. I haven't found much and the ones I came across are basically a normal power supply (AC => DC) where line voltage is being converted to about 10V - 40V with a huge resultant increase in amperage. Is it really that simple? If so, why the lack of interest?? Not worth the bother?? Risk of ELECTROCUTION deterring folks??? Heck I'm still trying to figure out stepper motor control...and it's tough going but here is something that looks much much easier.
I'm looking for additional info on this so please provide links and anything additional that that helps.
