This is a page with information on my project of building a DC to AC square wave inverter for my Hobart Cyber Tig welder.
Objective: to build a high power inverter that allows converting an "old iron" Hobart Cyber Tig DC TIG welder into a AC/DC arc welder with advanced squarewave output features comparable with expensive modern welders. While I try to use adequate components, I try to source them as cheaply as possible.
