To answer questions, I do all kinds of welding, fabricate Gates, light poles, and yes, sheet metal work. I use a lincoln weld pak 155. Leaves some slag behind. Was just thinking if I went to a new machine it needs to be gas shielding.
This is exactly the kind of stuff my Brother did with the Lincoln 135 I had before I bought the Eastwood unit.
This is some of his work.
Custom roof vents, gates security doors, custom truss brackets, all kinds of different stuff.
