I bought a cheap harbor freight mig to weld thin gauge metal, It splatters something terrible so i opened the case to find only a transformer and a few diodes, I hope to add a inductor to help stabilize the arc. The welder is 70-90 amp output, I have a high current air core choke thats heavy enough but i need to add a core of some type to raise the inductance. It has a2" round I.D. I need a sugguestion of a type of core to add to it & maybe a value in mh ?
