My Century 250 MIG welder is getting uppity. Welds good then shitty.
Something in the wire feed keeps snagging

I have a Lincoln LN-7 spool gun or wire feeder unit. Has anyone ever put one
of these units on a Century welder. How does the hookup go?

Most feeders you can change the feed tube in the line. Check for build up
on the rollers.

BTDT, everything multiple times. Sick of it. "The Kid" suggested upgrading
to the better unit, good idea if things are compatible.

Just a cheap fix to try .......... put an .045" liner in there. The
problems you describe can be caused by a dirty liner, and the oversized one,
even when using .030 or .035 takes a long long long time to fill up with
crud, plus will take more bending before squeezing the wire and causing it
to get uppity.

I do it on all my wirefeeds the first time I change a liner.
