Years ago a guy gave me an old aircraft gen that was made into a welder. It had a v-4 Wisconsin and belt driven. I think it said 24 volt,300 amp on it. Only Have the gen left anymore. Think after all the years I would like get I going again just for a project.1 Could I run it with a less bulkeyer engine that used to drive it 2.what hp. 3. When it was belt driven it ran in the same direction as engine, or could it be direct driven which would make it run the opposite way it use to.4 What kind or rated rheostat would one use.5.what rpms, and can anyone send a sketch a diagram of how it would be wired from generator and through what components to ground and shooten iron. Suppose I will get scolded for asking all this.|
GOOGLE "building a welder from an aircraft generator" for LOTS of info, from Pop Mechanics etc., etc., from
back in the day.
Here's ONE link:
Looks like 20 HP is recommended for full output. I would THING the DC generator would only work in it's designed direction of rotation... is the rotation listed on the nameplate? You need a field rheostat, as well as a big reluctor to stabilize the arc.
Surplus Center, mentioned in the link above, used to sell such generators, parts, and welder kits, along with instructions. A quick look at there web catalog didn't turn up any of that still listed, but you might call or email them. This post was edited by Bob at 11:37:44 04/17/13.
