try this, take a small piece of scotch brite pad and a small metal closepin and attach it before were the wire goes to the pulling wheel. it will clean the wire as you weld and reduce splatter.
they make "very cheap" little cleaners that install on the wire right after it comes off the spool. have had good luck w/ wire bought at attwoods country stores. also welding splatter spray helps too, but I always forget it. :coffee2:
