New to the site. Just want to say Hello first off.

Now, I have a SA 250 with low hours that digs great for beads. Is there a way to get this machine to stack metal like the old 200 do. I sold a 68 red face that would slick a sick cap on and want to do the same with this 250.

you can either roll the rac on the machine or spend 300 to 400 and have a arc force control installed which i would rather recommend

Thanks I forgot about arc force switches. Seen them on 200 machines never 250s.

My SA-250 is a gas burner and stacks like a dream.

Any idea where to get and how to wire an arc force dial?

roll the rack and set the ocv's between 89 and 91 and it will carry more iron and have more travel speed than any other machine lincoln ever built mine is a 98 model

I've been told to roll the rack one half the center punch mark. Does this sound correct? I also need a refresher on setting ocv's. I used to set my 200 by the aux outlet (120 dc volts). That machine would paint a cap on like spreadin peanut butter on toast.:D

thats about right on the rolling part. Never more than 1/8". OCV stands for open circut voltage. has nothing to do with your outlet. you check it at the output studs. should be around 90-93 for a sa-200. I dont know about an sa250. They have a totally different exciter and might run a higher ocv. My buddy has a 300d and it runs around 112ocv's. As you roll your rack your ocv's will drop. 1-Set your outlet at 120 with your high idle. 2- check rpm's and verify that you are not exceeding maximun rpms for your generator. (if you are your exciter probably needs a rebuild). 3- roll your rack and check your OCV'S, A half a prick punch makes all the difference sometimes. My sa 200 has 120 at the outlet and 92 ocv's. it was 99.5 before i tweeked the rack.

Got the machine used for $400 with 200+/- hours from a rental company. Still had the factory air filter from 1986. I had to rebuild the injector pump so I know the high and low idles are good. Next time I fire the old girl up I'll be under the hood!

As for the arc force dial- A shop in Evanston, WY I delt with has the parts but I don't know enough about the 250 wiring to pull apart a perfectly good machine.

the apparatus that holds the large brushes in your generator. there are two prick punches that line up on the same side as your air cleaner. If you ocvs and are between 89 and 93 and your outlet is 120 then it prob is perfect already but its worth checkin:cool:
