I have had my little mig welder for about 5 years, the best tool I
own. It is a 220v, I cannot remember the amp. but i use 100% argon, and
a 80 cf tank, i had a smaller one, but when i got it excanged they gave
me the bigger one, I pay about $16.00 for the exchange and own the tank
It last me about a year. and that is with one or two big projects. a
roll cage.. it works fine for DOM steel or mild steel, and i have gotton
good at it. but i have never been able to master aluminum with it. i
have tried seveal times but always look bad.. I can make small tack weld
on aluminum about a inch or two long but not much longer.. and i have
never been able to make a water tight seal. on aluminum.. I have just
finished a set of header for a motor cycle motor in my DSR, I used a gas
torch for that.. but that is a nother story. here is a site that will
answer most of your questions
