I have the Lincoln Weldpak 100 - 115v . 10 years old never had a problem . It can weld up to 1/4 inch with multi pass . Cost about $400 for the new Weldpak 140 now great for the garage .

If your building on car every day for a living then i would suggest the 220v Mig or if you just have the $ to have it .

Ive pushed mine way over duty cycle alot and it has never quit. Great tool for the money. Most my experience welding you run a bead stop clean it check you work then start again. Duty cycle fits right in.

For butt welding i did have to learn with it im running the .030 flux core . I think the .023 wire with the bottle would have givin me quicker results. I havent converted yet this is my second car and sheet metal work is limited here.
