Mig welder questions

Good luck in your quest for knowledge!
Just so you know I have owned my welding shop for over 22 years now.
I just bought the new Miller 211- it will weld on 110v and 220 volt and comes with a easy to switch out plug end dependant on voltage.
It will auto adjust the temp and wire speed for the material you are welding on and is easily moved but I bought the miller stand to go with it and a bottle sized C-60 75/25 gas mixture (75% Argon and 25% carbon dioxide- the extra percentage of carbon dioxide helps cool the sheet metal during welding process. If you were welding any other metal or thicker- go 95 / 5% on the gas.)
Use .023" E70s wire (E711s is flux core and not good on body panels) for the sheet metal
Spend the cash and buy a decent auto change helmet ($75.00 or more) trust me... it well worth it.
If you have any other questions pm me directly here and I'd be glad to help. Education is better than getting burned.
Oh yes, buy a good pair of flexible and comforatable welding gloves. those hot shots on TV welding with no gloves - are idiots. You dont need skin cancer.

Good luck!
