[QUOTE="Tractortech, post: 6957361, member: 13204"] Now Then.... I'd also seriously consider a replacement truck!! I assume this is a 4WD pickup type thing?? I've only ever done MIG with cars other than pre MIG and it was Oxy/Acetylene welding. I welded new panels and patches in a Ford Cargo cab floor area, sills and patches on a Subaru pickup and some others with the gas. I've done a few cars with the MIG since I got it. So, since gas is out of fashion nowadays and I've never done TIG, here are my thoughts..... Rust or corrosion will be twice as much as you're expecting.. TIG welding is a 2 handed job, look carefully at where you'll be working,,, can you work on it with 2 hands comfortably?? Paint and more so, car body sealants oooze out from joints when heated and spoil any welding. The metal is so thin & delicate, progress will be slow (TIG might be better here) as you'll make holes if too much heat and the rust from underneath a good looking panel will surprise you.. There'll be sparks, hot molten metal, dust and other such cack to deal with. Welding has to be continuous around any repair for the MOT (quantity in case there's little quality type thing!!).. Long term, a MIG will be more use and have more capable users than TIG (don't let the wire corrode or it's difficult to work with.. I set off to weld an exhaust hanger on the back of a Vauxhall Nova and finished up at the rear seats!! That was all MIG. The Cargo was all gas. Floor pan both sizes, structural members underneath, lower back wall full width!! I welded a sill on my own Cavalier after much cutting and drilling to get rid of the old corrosion... So,,,, to sum up,,, and this is only my opinion,,,,, it's a horrible, horrible job... Someone may be along shortly to put it in a better light.... ? [/QUOTE]
