Have one in the shop. Got a lot of use until recently... It needs some love (Failed megger test. Also needs bearings), but will eventually be back in service.

VERY nice machines to work with, if you can take the noise. You do want to work the voltage and heat controls over the entire range periodically to keep them clean. Also need to watch the brushes, brush holders and commutator, periodically blow the dust out of the top end, and keep the bearings greased (DON'T overgrease, or it gets all over the place and will lead to problems).

They are a nice TIG machine, but you will either need to scratch in or use a starter. Do you have one with the remote current control?

motor generators

Used a similar unit to burn DC stick and was a very smooth burning supply voltage which was nice when welding in rusty tanks and hoppers with 7018 hi low rod . Used in a strip mine the noise was not noticed and the 3 phase results in a clean power DC with a lot less ripple compared to single phase ..also draws less current running at 440 industrial power ..3 phase 440 it totally industrial power you wont find it in any domestic use.

What puzzled me is that a generator is basically nothing more than an electric motor that's being driven by some power source (waterwheel, gerbils, whatever) and vice versa...an electric motor is nothing more than a generator that has had some electricity applied to it (off the power grid, Uncle Fester's teeth, etc.) Motors and generators are basically they same thing, just mirror images of each other.

So it seemed kind of dumb to me to USE electricity to RUN a motor to DRIVE a generator to produce...ELECTRICITY.

Remember there is a difference here, its using an AC motor to drive a DC generator.

So it seemed kind of dumb to me to USE electricity to RUN a motor to DRIVE a generator to produce...ELECTRICITY. Kind of wasteful and inefficient, what with all the friction, noise, heat and other losses. I didn't realize that a transformer-based welding machine wasn't something that's been around forever.

WRONG...There HAS been transformer welders around forever!!!
BUT the reason they built this doesn't have anything to do with that...it's because they welded SO MUCH BETTER than a transformer welder!
Screw efficient.... it's all about that SWEET ARC and not getting choked to death with exhaust fumes while indoors, plus being three phase they were somewhat efficient

Yes i have a starter with the Machine you move the leaver up and the welder starts then you push the reset button and move the leaver to the bottom position and you are away to weld .Have noted what you have told me .Kind regards john

dc welder

Could you tell me what the setting would roughly be for the tig please .Kind regards John

Hmmm...now I'm beginning to see some method behind the madness.

Did they do this because rectifier-based DC welding machines didn't exist yet?

[metalmeltr]

Anyone COULD use this welder they would need a generator or rotary converter though.

[usmcpop]

Selenium rectifiers date from the early 30's but the reliability and cost were certainly factors. Practical AC welders came about in the latter 1920's and the selenium and diode rectifiers were later than that.

Welder

Would some one have a workshop manual for the welder.ie if i could have a copy will pay for copy. Seams to run well a little noisey but has the fine adjustments for Tig welding .Kind regards john

First of all has anyone got one of these welders ? Could you email me [email protected] .Many thanks ....john

Lincoln welder

I bought one of these welders a while back for twenty bucks to use as a tig machine. Not having three phase in the shop,i converted it to engine driven since the generator is self exiting and use the existing motor as a big flywheel. It is kind of and antique but runs a really smooth arc in stick and makes a good little tig though the controls are a bit touchy (could be due to age/dirt). I know this was a lot of work to convert and old welder,but i did it to prove to the other so called welders that work for us that there is something else out there other than a point and squirt (mig)

I know this won't help much, but we had two rows of these in the stick welding room at my vocational school back in 1980-81. Got me a cert using one of these. It ran the 7018 pretty good. Then, I joined the AF and didn't get to wield my mad skills. I haven't seen a machine like that since I left the votech.

Odd lincoln welder

I remember 65 years ago the blacksmith in my home town had one. It was electric motor powered.

Hi to all going to start tig welding with this type of welder .so will keep you informed on how it preforms .Regards john
