Problem with welder... no wire feed
My lovely (or not ) MigMate welder has been misbehaving.
when i press the trigger, the motor whines etc but no wire moves.
ive taken the nozzle end apart, and hand fed wire down. it seems to be ok then stops solid. i can eventually pull the wire through with mole
grips!!
any ideas or suggestions?

Have you tried tightening the wire feed screw on the feed mechanism?
On my migmate, as the reel of wire reduces the angle of feed changes and it needs the screw tightened to compensate.

Have you had a look at the wire. If your garage is anything like mine and your set has been in there over winter the wire could have started to go
rusty and this causes slippage in the rollers. Solution is to clean rollers and bin reel of wire.

Usually feed roller tension like James says or a melted tip. I have had a problem before with too much pressure crushing the wire. Also check the reel
and make sure it's running off smoothly, I had a bad one with the wire running under the next strand so it kept locking.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Oh, ok. Guess I got too excited at thinking I knew the answer and didn't fully read the question!
Seems like you've found the problem your self! Just remove the liner and replace it.
Or atleast remove it and see if something's blocking it. Mine's made of clear enough plastic you can see through it.

I think conrod has it, if the liner is plastic, the wire can wear a groove in the liner and this can grab the wire, or the wire can wear through it
and when you put a fresh piece of wire into the liner, it hits the outer liner and stops dead.
or you could have a simple blockage, or a nipped tip..... you have to watch nipped tips, can be painful 
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
