    MIG gas question

    I have googled, and read the stickys but I can't seem to find a clear answer, and am still confused. I would like to add a gas to my arsenal. I currently have CO2, C25, and pure argon. I am not changing or getting rid of any of these. But I would like to add a gas that can hopefully do two things (because I REALLY don't want to go get two more gasses): I would like to find one gas that will let me spray transfer on mild steel AND work for stainless (in whatever mode). Seems like if I use anything other than a helium trimix for stainless there is a risk of corrosion and or discoloration? Is there a gas that would fit my needs?

    Or am I just better off getting something like a 98/2 for spray, and just stick to TIG welding stainless?

    98-2 will work for spray arc on stainless. Personally I would get tri mix and skip the spray for steel. If you get into heavier steel, use dual shield and co2 or 75-25 , whichever your wire calls for, most can use either.

    Yeah I am set up for dual shield already. I like it a lot. The reason I was asking is I have a buddy asking me to work on some stainless exhaust pipes for him, and I was toying with the idea of using the MIG instead of the TIG. And if there is a gas that I can get that also let's me play with spray on mild steel, then it is a win win for me.

    Order up some Blue Demon flux core stainless.HTP/USA welds is selling the same wire with their sticker. You're gonna love it and no better place to start than under the car on that exhaust, right ? It lays down similar to electrode.I had posted some oven drips I made a couple years ago when they fist brought it out It was 035 with LITTLE MIG LIKE TIG- BZTT BZZZT BZZT
