1937 Lincoln

[Shield Arc]

Picked up this machine today, Idealarc 300. I didn't realize these old girls had hot start!

 

[weldermike]

Wow man, way cool bud!

 

[Shield Arc]

Thanks Mike! I need to seek help, I just can't resist these old welders.

I feel your pain brother! I just cant resist vintage stuff, i love it and nothing beats it!

Can't quite make out what the last pic shows. Is that the hot start control? What kind of input power would that take at max output?

Never thought Lincoln used any other color than red.

 

[Shield Arc]

Yes that is the Arc boost dial / "hot start".
The manual says on 220-volt, 104-amp input. I'm looking for a new SO cord now, to replace the one that came on it. I'll set it up on my 90-amp breaker. I ran my old Miller 330A/BP on that breaker for years and never through the breaker.
I think these things first came out red, then went to gray. Can't believe orange is the original color.:shocked:

WAY COOL:thumbsup::thumbsup::cool2::drool: That would have been a top of the line stick machine in the 70's or 80's let alone 1937. A forerunner to the Idealarc TIG 300/300. I bet collectors would pay a lot of money for it. One of the welding supplies here as a big old Lincoln buzz box on display about the same size and it is red. I doubt orange is the original color but maybe who ever painted it was an Airco fan???:laughing: It looks in amazingly good shape for it's age. That machine is proof Lincoln doesn't like change much. I think they still use the same style push buttons to turn it off and on, on some new machines.

"Never thought Lincoln used any other color than red."

I think they went through a few gallons of gray paint.

Maybe so! :laughing::laughing:

Cool old welder. That sure is a nice find.

Playing with the machine a little bit this morning. She doesn't stack to bad for a 76-year old. Vertical up hill, 5/32-inch 6010, 4-inch pipe, 5-G.

 

[Arc weld]

Guess you won't have much need to start up the "new" short hoods when you need to burn 6010?

 

[Shield Arc]

Actually the Short Hoods stack easier:thumbsup:. But the more I run this old girl the better she welds. Maybe it's the dust, or cob webs need to be burned out of her.:confused3:

Cool welding unit. I have not seen one that old before and I did not know they had hot start either. Most of the vintage idealarc's I see are about half that tall.

 

[Shield Arc]

I can't say I ever seen one this tall either. But back when I was working I didn't pay a lot of attention to welders, other than for where the start button was.:ashamed:
I have an original dial on the way from Stump Welding Supply, should be here next week.

I think those machines were the predecessor to the Idealarc TM series but they took the adjustable OCV volts off the TM series. The TM's were large units too and could be had in AC or AC/DC versions. For a 76 yr. old machine, it looks like it could pass code work welds just as easily as a brand new machine. I always figured the reason they made the old machines so good was because they were using a lot bare wire electrodes. I believe I read that cellulose rods were one of the first coated rods and Lincoln 5P 6010 wasn't a whole lot different from the original cellulose rods.

That 76yr old girl can still stack em up pretty good! Also has a lot to do with the guy behind her! She definately has good genetics! I want one

 

[rankrank1]

What is the OCV on the data plate? I could not read the number in your one pic. I am betting that welder just might predate the "Under Writer's Laboratory" mandate of limiting AC to 80 OCV and DC to (either 90 or is it 100 amps) for DC OCV. Most newer machine follow the UL listing requirements.

 

[Arc weld]

That machine has adjustable OCV's just like an SAE or SA 200. That's why it has 2 controls. Not as wide a variance as an SAE but still enough to customize the arc for different applications. I was trying to see what year the manual posted for it was. The upper right corner of the page didn't show and that's usually where Lincoln lists the date.

 

[Shield Arc]

What is the OCV on the data plate?

Max OCV 71-volts.

December, 1975.

 

[Arc weld]

That must be the last date they reprinted the manual.
