I have an old Volvo 245 that I need to get back on road. (They are starting to gain value!)At some point I need the rockers and front floor pans replaced and ALSO the bottom edge of windshield. A retired friend who has limited welding experience (but has done it) has offered to do it (I'm surprised!)if I come up with a MIG welder. I also know a guy who has done welding on car sheet metal - he works when motivated by hunger or boredom or interest - otherwise no go. Now, should either person come through, I may need to buy a welder good enough to do the job but cheap enough to afford.I think Harbor Freight but any thoughts as to specific models? Thanks!
