This Is Right On advise
I would use 75 / 25 shielding mix for that.
Only do it if you have the confidence of getting good penetration. You don't want that failing. The smaller machines are great for sheet metal. You may need more amps to get the heat you desire. Post a picture or your machine and part you intend on welding, I would do a trial run on a part with similar steel thickness. Clean every thing well
