Do you push or pull your weld puddles?

I welded all afternoon making panels and gates 14 ga, sq tube and 1 1/4 x 1/8 angle. The tubing is pretty thin so I pulled the mig if angle to angle I pushed. Pulling worked better on the thin stuff and I got better penetration pushing on the heavier stuff.

Thin to heavier, I use faster wire speed, more heat, I angle more heat toward the heavier steel.

Now 18 Ga car panels is another deal!!!!!
