So I've known for several years of the possibility of wiring on a Bridge Rectifier to a simple AC(buzzbox) welder to expand capabilities to include DC for use of 6010 electrodes. I'm in the market for a new multiprocess welder that can perform MIG(gas/fluxcore)/stick/TIG processes. They are very reasonably priced especially considering their versatility in the range of different welding processes but I have not yet found a welder with ask those processes and also the ability to run TIG or mig or stick with AC output. What is required to expand a welders capabilities to run AC output in terms of a DIY modification. How difficult is it to pull off and can it be economically viable for person with limited monetary resources? Thanks in advance.
