I use alot of .023 wire since best for welding exhaust and thin metal . don't see why you couldn't just buy a drive wheel for .023 . from the manual the wheel looks like just a standard wheel like miller use or Lincoln migs use . to me being a 160 mig it would be .023 and .030 instead since your pushing it with a .035 being that low amps of a mig welder , i have a lincoln 185 mig and it works like crap with .035 . the biggest wire i use in it is .030
