Okay - so now I'm convinced that I should invest in the gas bottle after everyone's comments. Thanks to all.

Here's a really good video demo of the Hobart 140 MIG Welder in 2 parts:

It's interesting that they suggest that you can use a paintball CO2 bottle, that can be refilled on the weekends (they say) at a sporting goods store.

I was kinda curious on the paintball C02 tanks, because I have a gun and two tanks (which I haven't used in a long time). Is anything special required to set this up over a normal tank?

shouldnt need anything different, unless you would need some type of bushing between the output port on the bottle and the inlet of your regulator i'm kind of thinking that a paintball gun bottle has a smaller neck and so on and the thread may be different but if you can bush it together and keep it from leaking its all good i would think

I'm new here, but take my advice dude, do not fill up your paintball canister at some sporting goods store and hook it up to the reg on your welder. A welding supply shop won't fill it, and if they do, they should not if they know you are welding with it. First, It won't fit, and if you have to go shopping for reducers to make something fit, stop. Rent the right tank, get the right mix. Trust me....
