Yes. If you are making an open butt weld, just remember to keep your gap tight and your amps low. For fillet welds, just keep in mind that you will be feeding a lot wire because of the diameter of the wire you are using.
Generally, yes, it shouldn't be a problem, especially if the TIG wire has an equivalent number assigned to it.
how much cfh of argon do you reccomend?
I would think that 15 to 20Quote:

Just remember to keep the mig wire off of the floor when you do this to avoid contaminating the metal.Quote:

A lot of times I forget to wipe off the "normal" TIG wire that I buy at the LWS, but it is a good practice that I am trying to get in the habit of doing! Obviously if you're welding really thin material, you'll want to get that tungsten sharpened to a needle point, otherwise you can wind 2 or 3 strands of MIG wire together to produce a thicker welding rod for heavier material as others (above) have mentioned.
