I can verify to small of a unit. I have a SP 100 Lincoln, rated at 90 amp 20% gas. I can't get enough heat soak into heavier metals. I was told to try and use flux core with the gas and slow the wire. I have not tried this yet. Go for a 220V. Lincoln runs sales at times with their pro units, you get at welder supply houses. You can get a better unit then sold at HD or Lowe's for almost the same price. The 220 will run off a drier outlet.

I have people tell me they can weld up to 1/4" with my unit. Not seeing it, they must be better than me.
