I've read through a lot of the welder questions, and one topic regularly mentioned is 110 v 220, with "220 is better" usually being expressed.
Now, I can understand the amps v. volts v. power issue (power to actually melt something is measured in Watts, which is amps x volts. However, power through a wire is essentially amp-limited, and power through a household circuit is very much limited by the breaker, which is amp-limited). 110v x 20a is 2200W, where 220v x 20a is 4400W, so 220v definitely gives you more power. However, how much power do you actually NEED for car work? Most of the time, you'd be welding 16-20g sheet, except for things like engine mounts, cages, and the like, where you might use thick-walled tube, but still you're unlikely to use much over 1/8" wall, even for a cage. Aluminum welding would require more power, but (IMHO) would also really require TIG. So, for steel work using MIG, how much power do you really require? What's the highest amp setting normally seen when doing the kind of welding you'll see on a 914 (or any other typical car)? |

I have a 220 Volt Lincoln MIG... Your correct you really only need 110 volt and when welding sheet you'll be on the absolute lowest setting for the 220 volt machine. The main argument for the 220 Volt Machine is that you can weld faster on heavier steel. I found that once I owned a welder there were alot of projects I wanted to do with the 220 volt machine.
made my own steel work bench(after I had the top bent at local fabricator) welded up a welder cart with rolling wheels Made a set of large jackstands with a pipe socket that fits right around the 914 jackpoint doughnuts. Steel shelves for shop. Steel Jig for Pulling rear wheel bearings. Point is you may think of a million things you can now make easily with a welder, sawzall and a jig saw to cut 14 ga sheet. What is not subject to debate is Gas Shielded Vs. Flux Wire... If you try to go without the Gas Bottle option on the Lincoln and other small MIG machines you will only frustrate yoursellf with crappy looking welds. Buy the Gas shield option and you'll be laying down beautiful mig welds in on weekend of playing with it. rob |
