  • How dark? auto dark shield

    With mig, a miller 200, and using .035 what darkness shield do you need. I have an auto dark helmet so I can adjust it. I think I read somewhere that its not the darkness that protects you from the uv light but the makeup of the lens itself, but want to be sure before I take a chance on going blind! thanks.

    From what i just found on the web it looks like a 10 would be ok for about 35 volts, My machine doesn't have VOLts on it I am on low at about 4 or 5 on the indicator. thanks.

      I was surprised that the plasma cutting was so high, I have a small one and they recommended a #5. -

          I think the recommended shade for mig is 11, but it all comes down to personal preference. A good indicator is to weld a bead, then stop. Lift your lid, & if you see dark spots, it's too light a shade. You shouldn't see any spots after you weld for a while. Personally, I use a ten or eleven when mig welding.

            Anywhere from 9 up to 11 depending on your personal preference. If you weld for a bit and when you lift your hood it is as if you have been staring at the sun and you are seeing bright spots turn it up a little until you find one that works for you.
