I have a flux welder its 125 amps. Its good for small stuff like fenders any thing thing. Ive had good luck with mine. Im just starting out but my 3 best friends are lisends welders so thay have been showing me some stuff. Now I have used a L E with gas and its a lot better. And as far as the gas blowing away out side :confused: My friends and I have done pipe fence with a mig out in 40mph winds and we never had that problem. Any ways just my two cent
