ASA240Z Posted May 22, 2006 Share Posted May 22, 2006 was up guys, My car is in need of some minor rust repair soo I was thinking about pick up a mig welder. I found a craftsman thats 80amps and is gasless. Would this be good enough for fix the dog legs, and floor pan? I'm sure it is but just wanted to verify with you guys. Any tips would help.

Brad-ManQ45 Posted May 22, 2006 Share Posted May 22, 2006 In aword - NO. T do sheet metal repair you need MIG. And specifically, C25 is the better gas to use. Plenty of posts about welding sheet metal on HybridZ.... Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted May 24, 2006 Share Posted May 24, 2006 I second what Brad said. Trust me the better the welder the better the finished result will be. If your like me a quality tool will really help me to get motivated about getting a job done. Quote Link to comment Share on other sites More sharing options...
Guest d3adp00l Posted June 4, 2006 Share Posted June 4, 2006 Gasless fluxcore welders leave an ugly weld which would require a lot more work to cleanup and correct the shape. Since it has a lot of foreign material in the welding area it tends to leave impurities and holes in the weld. Most wirefeed arc welders (which is truly what a gasless is) has a convertion kit to make it a "mig" welder. The right gas to use would be better explained at a welding supply store. To explain the gases in a simple way would be to say that its different gases in different percentages (25% carbon dioxide 75% argon) vs (100% carbon dioxide). Important note: don't use the oxy/acetyln gas for mig gas, Hehe you wouldn't like the result. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted June 5, 2006 Share Posted June 5, 2006 If you want effective welds and are not worried about pretty welds, than the flux core wire will be fine. BUT the problem most guys complain about with the cheaper craftsman welders is they only have 3 or 4 heat settings. They are difficult to get set right for welding sheet metal. You will spend all of your time cursing as you either burn holes in the metal or get cold welds. A better quality machine will make you feel like Jessie James in no time.
