Sealy mighty mig 100

Hi all
I have a home welder sealey mighty mig 100. Problem is that the motor keeps jamming. It ll feed for a bit and stops and then the motor just makes a high pitched noise.
Any ideas?

Welcome,
Broken tooth or two in their gear train I've seen happen on the older models.
Works OK until under load.

New so needed. If I pull the wire it feeds for a sec and then binds again

Right groove selected for the wire size?
Tensioner set correctly?

Ya I think the motor may be the issue all right. Just need to find one now. UK exit means UK is a no go for parts

Hi. So i took the wire fully out of the motor and motor spins freely. as soon as i put it in to the gun and feed through it starts jamming. is it the liner or could it be the wire?

Start with the tip - remove it and try the feed, if OK ... is the tip the right size for the wire?
If not OK, can you push the wire thru the liner by hand.
