WW2 hobart welder

[Mike K]

Thanks but that US Army Directorate of Publications link does not have the TM5-5120 manual listed . This particular Hobart welder manual is made of unobtanium for some reason . I have read that Hobart do have manuals and will freely supply them but this piece of equipment is a ancient vintage item and I doubt they have a manual that old.

Hello I just recently bought one of these too. Were you able to obtain a manual. There is a portion of a US Army TM addressing several Automotive support tools that covers this welder. It's only a few pages but it's better then nothing. If you don't have it I'll point it your way, it's available online.

Mike,

It's TM 9-834 VEHICULAR GENERAL PURPOSE UNIT EQUIPMENT. Here is a link to one you can find online, no download required. https://www.ibiblio.org/hyperwar/USA...fs/TM9-834.pdf

The pages you want are Pages 38-49.

So is yours up and running? According to the Hobart Brothers website they made over a 100,000 of these during WW2. Looking around the internet I found one with a serial number about 1500 under mine that was reportedly built July 1945. So I think mine might be right in that end of the war time frame.

Do you have pictures of yours?

Hi Matt

Many thanks for that link. Would like to see your welder and if it is the same model I have . No, haven't got it running as yet, the large commutator is a little worn/uneven, probably could use it as is but would like to have it machined down .

I did post some pics somewhere , will have a look. The Dodge engine in it is the longer block type from memory .

This example I have is a mobile setup with a Dodge light commercial axle fitted and the lunette towing setup , think this modification was done by the AWC Aliied Works Council, possibly in the Northern Territory

Mike,

Here is a real quick one just to get things going. I'll have to make an album once I really start into this thing. I'm trying to determine it's build date and based on some others that were inquired about on the Hobart Welders forum it appears to be late 1945. There was one built in July 1945 that was about 1500 serial numbers lower.

In this case it is sitting on a wood body Ben Hur trailer that somebody had stripped the body off, reinforced with C-channel cross struts and added a plate deck to the trailer. They kept the brakes but moved the parking brake lever to between the drawbars. For tool boxes they used two M-1937 Field Range Spare Parts Kit boxes.

The US Navy and Army Corps of Engineers had a Ben Hur looking trailer that was dedicated for some of these. 2 wheel, open C-channel frame with two large tool boxes that the fenders mounted to. I'm seriously considering fabricating the tool boxes and fitting some Ben Hur fenders to this trailer. It won't be 100% but it would be passable for reenacting events. That is assuming we get it running.

OK your trailer looks to be more engineered/sophisticated than the home made looking trailer under my welder. Found this pic somewhere .
