the 100 will weld 1/4 with flux, slowly, and a V groove. you can't do it flat out. that welder is just not strong enough. i wouldn't really bother getting a MIG hook up for that welder unless you plan on using it for bodywork.
with flux core, it will do for a mazda frame. the mazda frame is 3/16th i think, that or 1/8th. it's not really that thick.
i bagged my truck with a lincoln 100. now i use a lincoln 175 220. makes a world of difference. much nicer machine with great MIG capability. if you go to home depot, the price difference is like 150. it's well worth it
