I agree that the 6011 rods will burn through paint and rust but do a lot better if the metal is cleaned first. I picked the MM 175 because it will do 95% of my welding needs and I had 220VAC outlet already for the Arc welder. OT? why so many different outlets for 220VAC? /forums/images/graemlins/confused.gif I have kept the Arc machine for times when the mig wont do. /forums/images/graemlins/frown.gif I used some flux core wire yesterday out in the wind, worked farely well but requires carefull cleaning between passes /forums/images/graemlins/frown.gif I now have to make an adapter for the 22VAC outlet of my genarator to an outlet that will fit the plug of the mig machine /forums/images/graemlins/frown.gif
