I've got a small Hobart handler 135, 110 volt, in general when welding with gas you want a pushing motion so you keep your gas flowing out front, So that technique makes perfect sense.
I also have an A/C buzz box and a DC portable, I do OK when welding in position (horizontal) but once I get out of position I really struggle. When ever possible I try to flip things over to get the weld area horizontal.
