just to let u no i recintly bought a siegen mini mig , its a good little welder but the wire feed was letting it down as it was snagging the wire reel so that the wire wasnt coming through how it should , even though this is a cheap welder the design isnt grate ,
theres a spring and a locking devise it locks to a plastic circular spacer sort of thing , take it off its useless thats the problem
get a motor cycle sproket and the bit which u bolt on to the sproket get that and put that next after inserting the real ,
get a washer on to the locking piece and put spring onto wire feed hub then place locking piece on wit washer after spring then it will spin nice and freely and it will lock enough so the reel doesnt uncoil
