WW2 hobart welder

[Matthew P]

Mike,

Yes my trailer is rather stout. Whoever built it took a Ben Hur chassis, then added C-channel side to side on the front, back and several places in between. Then added a steel plate deck that must be at least 5mm thick. That will probably come off as the original Corps of Engineers welding trailers were a skeleton frame. And also it'll take a couple hundred Kg off of the trailer

Thanks for that image btw. It's better then the one in the manual and shows the Pierce governor linkage of which I'm missing. Mine has had an electric governor added to it, I've seen a few with that so it seems to be a standard later upgrade. But now I know what I'm looking for to return mine to original (fingers crossed that it runs at all)

Thanks
Matt

Mike,

Here's some interior pictures of mine. I'm hoping to narrow down the date better with some information from somebody on the Hobart Welders sponsored Weldtalk forum. But I think it's very late 1945. Then sometime after the electrically controlled governor was installed replacing the purely mechanical one. It's not original to any WW2 ones I've seen but it does show up in later 40's welders. That's the box directly below the engine control panel with the wires coming out of it. You'll note I have the engine speed knob in the center of the engine control panel. But no linkage over to the governor. That is all missing.

Ok I see the electric governor box , I will have a look at the welder here to see what governor it has fitted

Manuals...

Today I learned WHAT manuals I'm looking for finally. So here goes.

WW2: TM 5-5120
Post-War TM 5-5131 (Has the electric governor)
Post-War TM 5-3431-204-20P Repair Parts list for it and another welder 1963

The last manual is the only one I've found online so far. But the first one I located a copy on eBay and bought it. A friend has sent out a Signal Corps catalog for professional scanning before. I'm going to ask him where he had that done/cost and see about doing that for this. Since it seems to be nearly unobtainable and there is at least marginal demand for such a manual.

Excellent I could not find the 5120 manual anywhere seems to be a rare publication for some reason . I hope you can arrange the copying process.

Mike,

I have the manual in hand. It's the usual TM size, so like half of A4 paper size, but almost 200 pages thick. I'll be sending it out for commercial scanning as it's too thick and fragile for me to do page by page on my scanner here.

I'll keep you posted.
