Rust on the wire
Peter- You are spot on with one of the major problems with wire feed that are not used all the time, rust on the wire.
The wire wipe idea is a real good one. The rust on the wire will ruin the wire tube as it accelerates wear cause uneven or jumpy feed, wears the tips etc. I remove my wire spools when not welding and store them in a good tight container with desiccant bags. Learn this hard way when I had to throw out a large spool of wire that had gotten rusty.
The other little kooky thing is if you use your mig to weld aluminum you have to have a separate wire liner (generally plastic I think) to use with the aluminum wire or else you get cross contamination and a lot of sputter and nasty looking welds.
Thanks for the reminder as I will remember now to include that in tomorrows class.
Cheers Phil
