Weird. Makes YOU laugh, yet I dropped my laptop and ran screaming like a little schoolgirl. Very strange.
can this be converted to mig?

Hilarious, but sorry- I had to kill it. A little past our family-friendly policy.

For anyone curious about the straight CO2 thing...
Yesterday, I found enough parts to adapt my Argon flowmeter to the old CO2 pop cylinder that I've had laying around for a few years. So, I installed the gas solenoid in my machine and switched everything over to MIG. 0.025 wire, tip, gas nozzle, flipped the drive roller, and did a test zap. Not bad. Now- In my haste, I forgot to switch the machine's polarity (duh) so a little later today I will do that, and see what happens. I can't get too comfortable because there's not a lot of gas left in the cylinder (and it's too old to be refilled) but I'm an experimenter by nature...
EDIT- Just swapped the polarity, and did some test shots on 1/8" steel. Getting a nice bead with decent penetration. There IS still a bit of spatter, but I think SOME is to be expected. Need to play with the settings a bit. I have the gas flowing at about 35CFH, and I need to play with the feed speed a bit more.
Next, I'm going to try some thin sheet- Kryptonite to the flux-core!
EDIT2 (LOL) initial tests on some 20ga sheet went well!

that's really cool!

Yes- rather amusing. I did some more playing around and got some pretty good welds. A wee bit of spatter here and there, but not bad really.
A couple nights ago, I FINALLY got around to buying a cylinder of Ar/CO2. Very nice. Now, I have to learn a whole new range of settings... Dangit!

is CO2 cheaper?

Yes, but not by a heck of a lot. The big cost is the cylinder.
The annoying bit is that like any pressure vessel (like your BBQ tank) you only have so many years before the tank expires. I kept thinking about that. For the amount of GMAW that I'm going to be doing, I'd probably have it filled maybe twice before it's out of date, Yeesh.
I ended up buying into an exchange program. One-time "buy" fee and I "own" a tank. Whenever I need a refill, I brink the empty one in and they give me another full one for the cost of the gas. Since they are being exchanged each time (not refilled) my tank NEVER expires. Seemed like the smarter way for me to do it. I'm sure it cost a bit more at the outset, but I never have to buy again. I went through a major national chain, so I can exchange at any of their stores- I have 4 or 5 of them in my effective radius.

I used to use Airgas for argon. Bought a tank from Harbor Freight, went to Airgas, told them I needed gas, switched out tanks, and I was on my way. I think I payed like $20 for a 20 cu.ft. fill.
