  • Man, I do love Mig welding!!

    I've been using a flux cored welder for several months, and recently upgraded to a Mig/FC unit. I've played around with it a bit using flux core, and I finally got around to trying my hand at Mig welding with shield gas. I couldn't believe how much cleaner my welds were, and how much easier it seemed to be to lay down a bead. Why wasn't I doing this months ago??

    Also, I had picked up a 20cu.ft tank to use with the unit, and my local welding supply company gladly traded me up to a 45cu.ft tank for only $44 more, which included the gas! Hopefully I can get at least 3-4lbs of wire out of it, but we'll see.

    Quick question, what is a good gas setting for 1/8" mild steel? My welder is a 110v 90amp unit, and I am using .025" wire. Thanks!

    20 cfh works well. You don't miss the smoke and spatter with the flux core?

      Well, I don't mind the smoke and spatter as I do a little arc welding, too. But I won't miss it!

        I get good results with 15 cfh.

          If you are welding in a garage or the like and there is no breeze blowing around you, you can go as low as 11-12cfh. If you have the door open you should run it around 15. Unless you're outside, 20 is high.

            Not to steal this thread, but if you're using a long (i.e. 20') gas hose, do you need to figure for a pressure drop and, if so, how much?

                Bob, I sometimes have 30 or more feet of hose, never had a problem with flow.

                  Bob,

                  The issue is volume, not pressure. As for workable flow rates, I've run as low as 8 CFH with CO² on my old 135 with no ill effects.
