I got 3 of these tanks that are used for beer kegs. They look like they're about 40cf and I was thinking about getting them filled with co2 and using them with my MIG.
Has anyone else tried this?

 

You will be in globular transfer in mig. Normal is short circuit, and the top one is spray transfer. I wouldn't waste my time while you can just get a argon c02 mix for prolly cheaper, and i don't see how you would regulate the flow of air from a keg?

 

What are you describing when your talking about globular, short circuit etc? I don't see how its relevent.

I'll just use a normal regulator on the tank to regulate flow.

 

Globular transfer is a type of welding that is usually used with straight c02. It was the first type of mig welding process that was very messy, and they only used it because thats all they had. They found that buy using an argon c02 mix, they could get a tighter finer bead with little spatter. And spray transfer is lil to no spatter and a very fine defined bead.

And yes it is relavent.

globular



Ok here is short circuit <====Most common sounds like crackling bacon.

here is spray transfer <====most precise, need an advanced powersource to utilize this type of welding.

Fronius is the best in the business, read up on that stuff. Don't waste your time with co2

Don't lie. We all know your just trying to get your deposit back.

 

I dont think anywhere would fill your beer kegs with co2.

Atleast up here.. you have to get your bottles from the gas supplier.. and its a around $50 a year per year to 'lease' the bottle.. plus filling etc.. and they only fill (you trade empty for full) bottles of their kind (only can get from them)

 

I think he is talking about re-filling the CO2 bottle used with keg taps and not the keg itself.

what about a 2L pepsi bottle?

Ya they're metal tanks for the co2 used with beer kegs. They're just like any other tank used for pressurized gas, except acetylene of course.

So noone has done this; hmmmf guess I'll just try it anyway
