Duh! Your right Dave, I was thinking dia. Its the area that matters, 40% increase to .03 , 90% increase when you go to .035 . So guess you'd need twice the current to maintain the arc, assuming the same voltage and wire speed. Like I said my machine sets those for me. Do you keep the voltage and wire speed the same or adjust for wire size. Assuming your welding the same material?
Free advice is worth exactly what you payed for it.
