I have a Hobart 125 wire-feed welder that came with .030" wire. I picked up some .035 wire and, without thinking, a set of Lincoln brand contact tips. Any reason to think they won't be compatible with my Hobart welder? The threads are the same diameter and pitch, but the length of the threaded section of the tip is much shorter. I can't see why that would really matter, as long as they screw on tight.
Thanks, Mark L.
