View Full Version : Bought an old TR-301

01-24-2014, 08:00 AM
Called up my old landlord to see if he'd part with his Hobart. It's the machine I learned on a couple years back

She's a heavy sonofabitch

I call her "Hobie". Sticker on the inside says she's a 62.

Solid copper baby

She can kick out a little bit of current. 1-425amps. The torch is rated for 250 I think

Post flow adjust, high frequency adjust, water cooled, she has all the bells and whistles


Got the new Weld Tec torch, pedal, regulator, tank, several pounds of ER4043 and ER 308 and accesory kit for $500



She's a sweet ride


Me and you babe, looking forward to our next 50 years :)

That is a nice looking machine. What kind of water cooler will you be using?

Nice score

That's a cool old beastie :)

It's even older than my Airco - that's good in my book :D

Gotta love a classic.

Nice!! Reminds me of working on old Hobart battery chargers.

Thanks guys! I'm glad you like her. Hobie is setup for a garden hose right now. I have an indoor spigot nearby so I'm probably just going to use that.

Man, the lines on that machine are sweet for sure. Stuff had so much style back in the 50's- early 60's. Women always wore dresses, men always wore suits to dinner. Ppl just took pride in how they looked. Cars had style, buildings did too. Even machinery such as this was painstakingly crafted. It couldn't be done in today's industry. It would cost a fortune to build something with the same materials & level of craftsmanship.

You think of the craftsmanship alone that went into just the sheet metal dies that stamped the shell of that machine. Detail & flow. I watch a lot of old horror movies from the 50's & every once in awhile you'll see something like this in the background, etc.

Nice machine man.
Couldn't agree more, companies used to be able to make things look good and still make money on them. I have always liked the looks of these machines, mind if I ask what it set you back?

Ran into the original owner last night. He gave me the original torch cover for this machine. Its LEATHER!


Does anyone have a manual for this old machine?

Good old trans-rec machine...reliable and solid as a rock. I do not think you do but do you have HF switch with that machine? If so you got aluminum capability. Far as SMAW i like those old trans rec machines over anything modern save a synchrowave for burning rods.

She's got the HF switch, and a frequency adjust knob to help tune it in! Works nice on Aluminum.

I welded some stainless flanges to a cast iron manifold with it last weekend, turned out pretty good for an amateur like myself.

I wont say awesome but I will say good job. I assume you used a nickel alloy or SS rod to pull that weld off were it will stay put. ??? Very difficult to blend the two ascetic wise with even with a pure nickel filler.

02-22-2014, 09:42 AM
Yeah, I used stainless filler and just cleaned the crap out of the cast iron with a stainless brush and a 80grit wheel

Cool old welder. Do the lights dim when you hit the pedal?
Is that a rx7 or mk3 supra I spy?

Mike just remember when that salesmen is trying to get you to buy that 7+ dollar lb smaw welding rod for iron.....its basically nickel and go when you cannot identifif. Those ss tig rods have more then enough nickel content to pull off weird joining s. Nickel is cool because it will alloy with just about any carbon steel and join with iron on the fly, + it has good stretch capabilities to endure the shrink from iron welding. Hence these fancy nickel (super special alloy rods) i see for generous money.......BS. Please do not by into that crap. You can make nickel alloy join with any iron made after 1940 in general. Far as welding iron goes if the situation is real serious I will just buy square iron cast filler from harris and grab a couple cans of flux and go for it with my torches avaliable.

go to the hobart welder web site and ask for one. When hobart was broke up and sold off. ITW hobart ended up with all the books and they scanned them all. If they have one you can get it e-mailed to you.
