Hey guys, new member here. I have this old Airco Wasp AC/DC 225/200 gas powered welder. I got the machine in running condition form a guy I know for 300.00 bucks a while ago. Since then, I've completely tuned up the Onan CCKA and the thing runs like a top now. I had to rebuild the governor too as over the years most of the springs had been replaced with the wrong ones and it wouldn't hold speed under load. Anyway the thing runs well now and now I'm moving on to the weld/gen side of things.
I'm trying to find some liturature on this thing. It appers it was built by Miller, and it looks like a cross between AEA-200 and an AEAD-200. The differences are the AEA-200 is an AC only machine, and the AEAD-200 switches from weld to gen. differently and has different covers. I think I can get enough from the two manuals to know what I need to know, but I was hoping I could just download the correct one from Miller. Anyone recognize it??
Right now I'm focusing on getting the gen. side working right, and it appears it has a regulator issue. I adjust it to 60 hz. and it puts out about 145 volts AC with the fine adjustment at 100. If I turn down the fine adjustment I can get it down to about 130 volts AC, but something's not right.
Anyway, I'm hoping to find some wiring diagrams and then I can open it up and go from there..
