It is possible your back cap on your torch is leaking air into torch, or the connection between the collet and torch body.

Hey guys, that Argon tank turned out to be the problem. It was contaminated somehow, and that's why the welds came out so bad. I hooked up a new tank, and everything is good as new! Thanks for all your help, I hope this helps someone in the future!

Contaminated tanks
I've come across this problem before, when working in a large aluminum fab shop. I was told that tanks get recycled and used for different gases over time, by the gas supplier. I don't know if this is true, but it could be why the argon tank was contaminated.
