4-5 years ago I bought an HF MIG-100 wire feed ( flux core ) welder, it never fed quite right ( jumpy ) and eventully the feeder stopped working, when the rubber wheels wore a groove... I got a new redesigned feeder under warranty from HF and installed it a couple years ago, never bothered to see if it worked, never put the spool back in, cause I didn't think it would work better than it did.... fastforward to yesterday when I had to weld somthing and I don't have the arc welder anymore ( at our other house ).. so I got the welder out, put the spool in it, and went welding.. and it now feeds really smooth, welds decent too.. I was welding 1/8"x1/4" angle iron, and it did take a bit to get it hot, but it worked..
then I practiced on some sheet metal, and I can't run a bead without burning thru, but I can spot it togther..
