changing the spool in a MIG welder

[welder19]

It should have a lock nut, that way it will say inplace and the spool will spin free.
They make little felt cleaners and lubricators that just slide on the wire and have a clip to keep them on, they improve the performance and lengthen the liner life, I think they are like $1 each, I used to do the paper towel thing but the lube really helps and they are cheap so I started using them insted.

A cigarette filter works great for cleaning the wire before it enters the drivers. I don't smoke so have to bum a cig on occasion but one fillter will last a LOOONNNGGGG time, just run the wire through in a different spot.

I had the same problem with the wing nut (actually a nylon screw) on my 110V Lincoln self tightening. I couldn't figure out what that the actual problem was, so I clamped a small pair of vise grips on the wing-nut-like screw head to stop it from turning. This works well enough that I haven't bothered investigating the underlying problem further.

I put a piece of scotch brite pad folded around the wire and held with a wooden clothes pin.

After seeing Brad's self made welding table, I can see I need to make something similar. The floor doesn't really work that well and the wooden table I have now would be an issue to weld on!

I like to blow the liner out with compressed air whenever I change spools.
