How do you set amperage on SA200

[Nathan114312]

I am trying to figure how I can set a specific amperage on my sa200. It has ranges for example 80-130 but the fine dial goes to 100 so for example how would I set 125 amps? I have looked at some other threads but have not found my answer. Thanks

I use the face plate on SA-200s only as a reference. I find the spot that works best for a particular type and size rod, and mark the face plate with soap stone.
All my SA-200s have remotes so I mark them.

130-80=50 amp range.

Each 10 on your fine would be 5 amps.

Set to 90 on the fine dial for 125 amps.

And like CEP said, adjust from there to taste.

This is a good question. I havn't run my red face enough to get to know it. I do understand any amperage can be had at two different settings.
Which setting gives the better preformance. A low fine current adjustment or a high fine current adjustmet or are they the really the same.
I know, I need more hood time with the machine. Owning one is just an itch I had to scratch.

Thanks

Lower range, higher fine will give you more arc voltage and makes 7018 very nice to run. Good arc starting.

Higher range, lower fine will give "an aggressive digging arc that is good for vertical and overhead" according to one sa-200 manual.

Thank you everyone! This helps me alot

I don't know but was told say the 120 to 190 to subtract 120 from 190 witch is 70 so each 10 would be 7 degrees.

Is that Fahrenheit or Celsius degrees?

[johnrbauer]

OK it is easier to figure 10 degrees I like that much better. Thanks for setting me straight

You got it, just in amps instead of degrees. Then add the 2 together for a total amp setting of the machine.

Nathan, I visualize this just a hair differently but am doing the same things as everyone else suggested. Second gear is 120-190 amps. That is 70 amps of difference. I few the fine control in percentage. On the fine control 0=120 amps=0%, halfway is 50=155 amps=50%, wide open is 100=190 amps=100%. Same as what everyone else said but for some reason my brain has always interpreted it into percentages and that was easy enough to know amperage roughly speaking. You never know unless you put a meter on it, but who cares. When it is welding right you know and the numbers will get you close enough to easily fine tune it.

Pretty clever for a beginner!
