I'm looking at purchasing either the Lincoln 180 or the Lincoln 140 MIG welder. I plan on doing mostly sheetmetal repair & replace work on my Mopars with it. I have access to much larger MIG and TIG welders anytime I want if Ineed to fab cages or anything bigger. I'm looking for something to keep in my garage at home. Which would you choose or have. My brother advises the 140 (110) version as its more verstile and portable for my needs.
