So many of you probably have this cheap flux core welder from Harbor Freight. It welds a million times better after switching from the cheap hf wire to Lincoln, but it still leaves a lot to be desired. After quick inspection I discovered that the Welder outputs AC. Anyone that knows anything about flux core welding knows that the electrode should be negative polarity in order for a good penetrating weld and little spatter. I have decided to rectify and filter the output of this Welder in order to make it into something better than just a cheap entry level Welder.
This website has proven instrumental in helping me convert my Welder.
No schematic for the AC to DC conversion of the torch output.
