Yes they are, DC rod probably works best but I am sure AC rod works too. I haven't done this myself but my father has a setup he's working with that's very similar to this. I think he's using 6 batteries though (I think he said in banks of two to up the amp's, which would allow him to weld thicker stock. I'm not positive on that though)

I should give that a try. My dad uses DC rods in his arc welder and has tons laying around.

A good reason perhaps to put an extra pair (or two) of booster cables in the car.

The alternator welder works...but it's not what I'd consider emergency...It would be near impossible to build one from scratch in the bush like the guys in the top article did unless they pirated essential parts from their trucks.

I was looking at some welding goggles but they said they were for oxy/acetylene welding only. Can someone tell me what's the difference between eye protection requirements for differnt types of welding, especially DC or AC welding versus gas-based welding?

Thanks,

Hi Blast,

Its not only eye protection that is required for electric arc welding. A full face shield is required to protect the face from the UV light generated from the electric arc as well. Electric arc welding requires a much stronger light filter than gas welding goggles. A full flip up/down face mask with a very strong light filter (the light filter is normally so strong that it is completely opaque to normal lighting conditions, hence you cannot see what your doing until the electric arc is struck). With gas welding, the goggles glass filters are much less opaque. So generally you can see what your doing in normal light conditions before introducing the light produced from the Oxyacetylene flame of the gas welding tip. Gas welding temperatures are some what lower and don't really produce UV light during the welding or brazing process. If you are doing any electric arc welding a proper full face mask is required. There should also be no exposed skin in direct line of sight of the electric welding arc either. This include all electric arc welding including MMA, MIG and TIG.
