Lincoln Sa200 wisconsin 4 powered Sheild Arc welder

[D Auger]

Looking for any and all info on this machine manuals parts books etc ...shes rusty crusty but I like them like this and the price was right Ive seen some on youtube but know were elese.

Figured someone on here would know about these machines it was stuck when I got it, flywheel fins snapped off different shroud on the blower I think someone over time swapped it out ?? with traces of yellow paint tag says its a ve4 3x31/4 but the bore measures to be 3.25 and one piston says std on top ?The reason I ask is I need two pistons for this as one was broken already and the other I broke getting it out only cast aluminum, bores look ok and saveable any idea what engine model this is tag on the welder dates it to 1952?
?All the sheetmetal is there had to heat every flathead screw and use a impact driver to get the sheetmetal off,it was in a barn for 20 plus....Years know one knew the history really commutator looks good and brushes are pretty thick bores on the cylinders have know sign of a ridge .
My plans are to get the motor running paint it back to its orgional grey and ad a grinder plug if I can what do you guys think ???

[D Auger]

Here are some more sorry about the rotated pics......Magneto was a mess took it apart cleaned it got that working well piston supplier told me today that the ve4 is std size 3.00 inch bore this has engine has a 3.25ich with a std marking ontop of one of the pistons ,leads me to believe the shroud probably rotted off and blew away and they put a ve4 shroud on it. Having a hard time trying to find pistons for this machine
So maybe the engine is a different model im not really up to snuff on the wisconsins?

i used to be into wisc motors about 20+ yrs ago. dont take my word for it, as i'm going off my memory. 3.25 bore was vh4-d motoer. also, the twin barrels and heads were the same off a tjd a(a 2 cyl), and maybe even the thd. so maybe the pistons are the same also. i never heard of the ve, but there were tons of vh4'd made . i may still have all my literature on tjd, th, thd, vh4-d, all 3.25 bore i think. i think many of the upper hard parts were the same, two cyls were like a 4 cyl, just chopped in half

“Shield Arc” I meant to say ..,and thanks 123 on the info I appreciate it .

Could your tag be VF4? Page attached from Wisconsin service manual.
I could not find an Owner's Manual for your code but manual IM172 (earliest code 2439) has the VF4.
Good luck with your project
Sorry for the sideways picture

[Blackslacks]

Its a VF4. Ive got lots of literature on these machines. Parts too. PM me with you email.

[D Auger]

Thanks KC51 and BlackSlacks I sent a PM

Good find! I was wondering if we would see that $100 Craigslist find on our site. Keep us posted on your project!

More progress torn down as far as i want to go ,got a new flywheel in and some engine parts .If any one has a machine like this with a grinder plug on them i would love to see pics of how its wired or a wiring diagram im looking to ad one on my machine?
I know they exist ive seen them on you tube and in google pics ,lots of square furniture nuts on it that were rusted solid !Pretty neat how the brass tag is on there marking the positive lug and steel marking the neg lug didnt find it till i blasted all the parts clean everything was painted over .Was there a sheild arc decal on the back of the tank ?
There is kind of a long rust pitted outline in the metal were something was there, only one with tank decals ive seen was wrenchguys 1947 model which had warning decals and carhart customs shield arc decal on the You tube .The shield arc decal looks pretty sweet and fits right on there and ive seen them on Lincolncontrolplates site so i may go that route
Thanks D

[D Auger]

Neg tag may be aluminum i will check later .

[Blackslacks]

Not sure if you have this.

Here's 1 of mine (1947) on my newly acquired service truck. It runs and welds fine, u prolly saw it on youtube. Good luck with ur project.

[D Auger]

Thanks Black Slacks ! I didnt have that drawing does anyone know how to wire a grinder plug on one of these ?
WrenchGuy thanks for posting your pics I love the service truck idea it looks period of the time !I like the compressor too looks like a Briggs Z on there also from the 40s era what make is it?

[crugg65]

If you do figure out how to wire a plug for your machine, make sure your power tools are AC and DC current. AC only power tools will burn up and they’ll wind up in the trash

Tools with brushes can be used with ac or dc on a Lincoln dc welder. The tag is meaningless to me. I have a harbor fart grinder that saiz ac but works better on dc on my sa200. Some metabo's are ac only so beware. Variable speed tools should only be used at full speed.

I don't believe your shield arc should be used for a grinder tho. Reason is: rpm from the Wisconsin controls arc voltage and the resistor grid selects amp range. Different rpm's will have different volts. The sa200's have a fixed engine speed around 1500 rpm so that volts to the outlet are fixed. The rheostat adjusts arc volts after the outlet so that the outlet is constant with fixed rpm.

[D Auger]

Actually it runs at 1900 rpm normal load speed and ive seen 3 of them with a plug on them the gen head looks the same and it looks like the receptacle that Lincoln had factory on the 2 cylinder lincwelders with the Wisconsin and the onan series as well with the slanted looking plug ends.
Im going to contcact Lincoln for more info .Thanks For your Help

[Insaneride]

I see in post #12 second pic, the nomenclature shows 2200 rpm max no load speed for that machine.

I'm sure 90 volts dc could run a grinder but are you sure the red machine is a dc machine? Without pics of the faceplate, that could be an ac version. I don't know but if you need/want an outlet; get it running first and find out your highest ocv. RPM's are a factor so use highest rpms as the sa200's are only good for 15 amps, your machine may be less.

BTW, your doing a a great job with restoration. Was neg plate aluminum?

[Insaneride]

From the diagram from post #11, it looks like highest volts would come from RED and INSIDE LEAD. I would also measure from INSIDe LEAD to OUTSIdE LEAd. Those would most likely be the only taps you could get the volts needed to run a grinder. Volts will depend on rpm tho.

fyi, 4 anyone finding these welders, remove the oilpan and clean the sludge out b4 starting. Then spin it over and check at the governor that oil is coming out the tube. This was the sludge build up in the engine on the above truck.

That is super sludge wow! Lol good advice

Hello everyone I know it’s been a while ,started back on the sa200 got it running still got a few things to clean up .
Wiring repair from mice damage prime and paint seems to run pretty well .
This machine was neglected for a long time had a wix oil filter that looked like a soup can prob 60s if I had to guess .
I checked for voltage at the rheostat wires and got some readings at idle so shouldn’t have a problem welding .
Pulled the pipe plug for the bearing in the back do you just pack a little grease in there as there is no fitting or tapping for one ?
Also found a factory inspection test mark which is prob rare to find on these under the grime .

[D Auger]

Have this machine up for sale on eBay in order to fund other projects,next machine I will be getting onto is a 1945 sa200 shorthood and will post this winter thanks all that helped with this project it was fun stay safe!

Somebody gonna hate me. I just dropped an old asphalt roller in the dumpster. Haven't taken it to the scrap yard yet. But it has a perfectly good looking and running Wisconsin engine in it. I just don't have the time to mess with it or I would have pulled it to sell.

[TomA]

Are these Wisconsin powered welders as good as the true SA 200? I note the Continental powered welders have an external Exciter and these do not.

I have 2 of these I am about ready to give up on. First reason, lack of electric start capability. I am getting too old and they don't start easy and are temperamental when hot.
2. They are too heavy to load in a pickup easily. I only need a 125-150 amp machine. I am going to start watching auctions for something smaller. I certainly don't want something too new. Have you seen that one that Wes was working on on utube?
3. One is the resistor type with taps. The other is the switch type. They both ran and welded. I selected the switch one and transferred all sheet metal to it, now I find it missing on one cylinder.
My son had a 2 cylinder Wisconsin one he offered me at one time but they are AC for sure.

[Jwade0129]

I was wondering if anybody would know where to find the armature bearing housing for the sa 200 juniors mine broke off during disassembly?
