That one was manufactured in 1986 according to Lincoln's service information.

 

BobC, Do you know if this one would have the aluminum coils or copper? Also this is a DC machine right not a AC/DC.

 

It will have aluminum interpole coils from 1974 ish to 1991

 

Not sure on aluminum or copper but, the machine is DC even the 110 side. Check your power tools before you plug them in. An AC tool will be rendered useless after using DC to power them

 

The stator coils on that machine would be aluminum. They switched from copper to aluminum in the early 1970s. Lincoln went back to all copper when the Classic I replaced the SA-200.

One way to tell is from the shape of the generator. A main generator frame that is round will have copper coils, one that is octagon shaped will have some aluminum coils.

To the best of my knowledge, the armatures have always been all copper.

Thanks for all the input! It is octagon shaped. Can the aluminum ones be changed to copper or should I not worry about them? Will this hold up for pipelining or should I look for an older model with all copper. The welder I help doesn't know alot about these welders he has a classic 300D and before that he had a mid 60"s SA 200. I've been using his to practice with and it does weld easier or slicker then the one I just got. The one I have works good and I can lay in a great bead with it but I will need one I can count on in the feild. I've seen other new welders brake out and have trouble with their machines and it's not a good thing with the job foreman.

 

There are a lot of aluminum wound SA-200s on pipelines and yours has apparently been working fine for more than 20 years. The design isn't all that prone to breakdowns, but if you're concerned, you should have a good, experienced repair technician carefully check it over. Any machine can break down, even new ones have problems sometimes.

Good luck,
Bob

 

Here's a pic from when I picked it up. I have taken all the sheet metal off and sand blasted it and primed it. I also purchased all new plugs, wires, thermastac, hoses (fuel, rad, overflow) got oil pressure & water temp gauge also. I power washed the unit after the sheet metal was off. Cleaned it all up and painted it. As soon as I get the sheet metal all painted I will post some better pic's.


Can't figure out how to upload the pic, can someone help with this. Thanks

 

Pic when I got it home. The pic was to large to upload.

 

Pic of how it looks after I took it apart, sanded and painted, and replaced all hoses & belts, clamps, added temp & oil pressure gauge, clear fuel filter, spark plugs & wires, I also added a brass ball valve with a hose nipple on it to change the oil easy when it's on my truck. I think it turned out pretty good for the first one I did.

 

Pic of the valve to change the oil. Just under the air cleaner you can see the hole the hose goes through then just open the valve and drain the oil.

:blob1: In 73 and 74 Lincoln tried going with Aluminum SHUNT field coils. The following (I hope) are pics of 3 different generator housings. ALL are constructed the same inside, except the 73 has aluminum shunt field coils.

I hope this helps.

 

Hey 63 Max you sure did a nice job on your welder. I am redoing a P&H welder with the F140 continental. It would seem that a lot of engine driven were built using continental engines. Keep on it and from what I've seen and been told they will last forever.

 

more pic's of the 86. check out my next project on another post, it's a 57 shorthood. the pic's say shorthood but i took them the same time i took the shorthood pic's
