There isn't one welder that will do everything. Thats why I have about a dozen welders at my shop. But for around the house, I have a Hobart 140. I use gas all the time. Straight CO2 is fine for thicker metal, but Argon 75 CO2 25 mix does a better job on thin stuff. If I weld outside, I put up a piece of tin or something for a windbreak. I use .025 wire on about anything I weld on my old jalopies.
