Whats the scoop on this,,
thank much,,,jim

Hey Jim, you are correct in that pushing decreases penetration assuming wire speed and stickout is the same, it may appear to have more pentration do to the shallow bead.....if you ever weld aluminim, you do have to push to keep the shielding gases ahead of the puddle.
