    Airco Bumble Bee,250 AC/DC;Single or Three Phase?

    How do you determine if it is 220 or 460?

    I believe they were all single phase, you need to look at the jumpers on the board for the incoming power to determine what voltage they are set for.

    They are single phase. But can wired for high voltage single phase by placing the jumpers in the right configuration. Take the side panel off where the power comes into the machine and the power leads go to the jumper board first. Here’s what it looks like for 230V

    Thanks very much. It was given to me after being stored since the early 70's.

    Cool. Good welder. Just blow it out and make sure the power cord isn’t rotten

    I love the Airco model names: Bumblebee, Wasp, Hornet, Super Hornet. Cool

    Blast from the past. Burned a lot with one of those I bought in 1980. Gave it away a couple of years ago. Virtually nothing can go wrong with them if you blow them out every year and lube the pile screw. The power cord tip is good, had a short once..."They don't make them that way anymore" which is fine with me, but you'd probably go thru two inverters and that thing will still weld, when your grand kids fire it up. I have it's CV cousin, MIGet Cav II, that still runs fine. As matter of fact, whenever I use it (when a machine is down) I wonder why I went all digital? After over thirty years, the only thing I replaced was a contactor. They are well fused, so whenever anything goes south....
