If your welder is just too big, sometimes you can get away with this. Try
holding the trigger so that the wire contacts the metal at 10 degree angle
or less. Sometimes you can cheat it a bit and still get a decent stitch
weld. Think of it as trying to weld to the front of the weld bead that you
are laying down. That way you are transferring most of the heat to the weld
bead that you just put down.
