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 agree that helmets can make a huge difference. I have used a Harbor Freight adjustable auto-darkening helmet for awhile now which worked really well until the head strap broke on both sides. The lightned state of the HF helmet was a little too dark to see things really well, and the darkened state was never that great, but I for the price it's a great, great starter helmet. It's solar and battery powered, has an adjustable tint from shade 9 to shade 13 and an on/off switch.
I just bought a solar only helmet from NAPA and I think their helmets are rebranded Huntsman units (although I'm not sure). It claimed it was a shade 11, but it wasn't quite dark enough for TIG and REALLY wasn't dark enough for MIG. So that'll be returned tomorrow. I decided to bite the bullet and ordered an Optrel Satellite OSE. From what I've heard Optrel is one of the top helmet manufacturers, and at $270, I should hope so!
