I'm just starting out on how to run and service welders, so I very much appreciate you sharing the knowledge you have. Thanks for dropping scholarship on us and getting us up to speed on how to test and recognize the failure indicators.
My SAE 400 diesel won’t strike an arc! The outlets are also dead! Where do I start? It happened in the middle of a job!!! Your advice will be highly appreciated!!!
Greetings ! I did enjoy the video on troubleshooting an armature. It lead me to ask: I have a Lincoln 300 amp SAE welder, all apart. I am having a six cylinder continental engine, which has little wear, rebuilt. Now that I have the armature out-I tested it with a 12 VDC battery and light. It behaves like there is a shorted shaft to the armature- all the commutator bars light up ! What are my options at this point ???
Hello, so when you test the exciter armature it includes the larger copper surface inside the stater. In other words, just testing the end of the armature should tell you the condition of the entire unit?? or is there a separate test for the larger copper surface that seats inside the Stator.
It really just depends on what your doing with it and what your budget is. SA200 if you dont have much to spend but need a high duty cycle and that is pretty simple to work on (you will work on it) or maybe just something smaller like a ranger or trailblazer might suit you better if you're just doing jobs here and there on the farm. Many like the SA200s because they are good bang for your buck and like I said simple to work on, no computer boards and inverters to go bad. Only real downfall of the older 200s is no AC power. Hope this helps
If the rotors armature is shorted will the commutator show a short on any area you touch on commutator or are some planes on commutator ok and some are bad? In other words if you move the wire clockwise directionally around the commutator will the lightbulb turn on and off, Turning on where there are shorts, Or do all areas on the commentator light up once there is a single short in armature? Sorry if this is a confusing question just trying to understand if the short spans across the entire amateur once you have a single short. Thanks
Yes usually if there is a short it will be on all com bars I have yet to see only one or random bars only short. But it is always best to run your test lead all the way around just in case. Hope that answers your question.
Yes I have, I’m sure you can use one but I just use the methods the motor shops around me use. They usually either use the light bulb method or a megger.
I personally don’t see a problem with bumping the rack a little if you know what you’re doing and have already set your ocvs. It becomes an issue when someone has other problems and think adjusting the rack back and forth will fix it. Just don’t go over 1/8” or so in either direction

Thanks for the video !!! You just earned a subscriber. I am in the process of rebuilding a SA200 and found this info very useful.
Thanks for the video. Keep them coming.
Love the videos not very much on the tube about the electrical side of these machines
Agreed
awesome channel. I have a miller big 40 gas that I'm working on. so ill be watching for any info. thanks

Start with primary winding brushes

Rewire the armature

Cool man good video
In your opinion, if you had to buy a gas welder, switch brand would you buy

Can you fix the armature or do you have to replace it?

@@ntxwelding626 yes thanks
Show how to test the shunt coils on a Lincoln SA 200 Thx
Did you say when the light is on mean the armature is not working it has ground
Ever take out the armature shaft?
I’ve got a decent wobble to my armature on a 68’ red face. Is my only option to replace it?
You get to the bottom of that? I have a wobble on a classic 3, bad bearing I replaced but am wondering if it's the way it's connected engine side.
Have you ever heard of a " growler " being used to check armatures ?
Yes I have, I’m sure you can use one but I just use the methods the motor shops around me use. They usually either use the light bulb method or a megger.
Paul from Iowa, looking at a Lincoln welder, won't generate power, What's the price of an Armature for a 10, 000 watt unit, ball park price
Which machine in particular are you looking at?
eBay
Hey buddy in search for a carburetor my sae 300 .it has thr international UC 221 , 6 cylinder engine any help will be appreciated
I have a Vantage 300. I think the rotor needs replacing. Can you recommend a place to buy the parts?
I use Bills Welding out of Oklahoma City
Hi Adrian, are you still make videos I wanted to ask you a question need some help
Kind regards

Thnk you very helpful
I hear so.e people saying g rolling the rack is no good, what your opinion on that?
I personally don’t see a problem with bumping the rack a little if you know what you’re doing and have already set your ocvs. It becomes an issue when someone has other problems and think adjusting the rack back and forth will fix it. Just don’t go over 1/8” or so in either direction
@@ntxwelding626 I got ya
Where you located?
