    Owners manual recommends a 40 amp breaker. Did you get the right machine? This kind of depends on the thickness of aluminum that your wanting to weld. You will definately have no problem welding 1/4" aluminum. And you will have plenty of duty cycle available to you for welding 1/4" aluminum too. If Miller hadn t offered a free Spoolmate 3035 with the MM 210 last year at this time , I would have bought a Ironman 250. So, in my opinion, as long as your not wanting to weld thinner than 1/8" aluminum you made a good choice. However, I will for warn you that it is difficult to wirefeed weld 1/8" aluminum. The rate of travel is incredibly fast. Not impossible, it just takes a lot of practice. I didn t like the rate of travel though so I bought myself an Econotig for welding 1/8" aluminum.

    Also, I bet over half the guys on this site would love to have this machine.
