Thanks, Steve. I was hoping for a better alternative, but what you say makes sense.

Hello,

I recently came into ownership of a Lincolnweld Type SAE 150J welder, also known as a a Lincoln Shield-Arc Junior, that I plan to use to build some mobile bases for some heavy machines and a few other relatively light-duty tasks, as well as fabricate some parts and jigs. Its serial no. 53802 seems to date it to 1941, and hard as I tried, its age and indestructability wouldn't let me walk away from it, even though it is 440V only. I am set up in my garage with a 10HP RPC running off a 60amp 220 line, and need to figure out the best way to power this welder. Specs off the plate are:

440V
12A
Rating: 30V NEMA
150 amps

Initially, I thought I had one option: a step-up transformer - probably 9kVa would do, since I don't do a lot of welding and wouldn't have reason to crank this to full capacity.

But I was wondering if there might be a second possibility: take this to a Lincoln repair shop and have the motor rewound (or leads connected) to make it 220V/440V? I haven't poked around inside one of these, so I don't know if this is possible, and I don't have the motor experience to do it myself.

Thanks for any advice.

Rich
