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 just learned to weld (kinda) on my own...a friend at work got me started and showed me the basics to get me started. I spent around $800 to get a Miller 135 w/gas, gloves, hood, cart, etc....
It is a better welder than I will ever need. I have never welded anything on the 914 that required me to turn it up very far at all. I have welded parts back together on my lawnmower, my neighbors lawn tractor, built some weightlifting racks for another friend out of 1/8" angle iron stock and 3/4" rod (you will be amazad at how many new friends you will aquire), garage shelves, welded parts on to trailers, etc.... I am 100% happy with it. I have welded up to 1/4" plate in practice....but then I started thinking---when would I ever need to weld something thicker than that?!? -greg Oh yeah, spend an extra few dollars on a good dual sensor automatic welding helmet...(just don't buy the absolute cheapest one they have). Dollars well spent. |
