My supplier is an industrial outfit, don't know if they will have the drawing quality. Might have to hit it with a flapper and use a sharpie?
He meant drawing as in shaping between dies.

But you can draw on it with a sharpie, either before or after you draw it into shape.
On your welder, if you have a light duty MIG setup already, that should be fine for sheet metal work. I have a Lincoln Handy-MIG, and it's been doing well for me patching fenders and bed sides. I'm not even a full power on it. It works well for the 16 gauge bed panels I've been working on.
