i just purchased my new miller 252, it has straight CO2 gas and i use it mainly on steel.

i am looking into making a fuel cell for my jeep and was questioning making one out of aluminum or steel. i do not have aargon or a spoolgun so aluminum would take me on a ride to get one or borrow some one elses.

i just want what ever input you guys have. like why steel wont work. i know its heavier. the cell will be a simple rectangle all except the bottom will have a sump. i plan on doin baffles or foam but not sure on which. i know their are some on the market for cheep but i can not find one that fits just right.

lets hear some advice
