Ive got a clarke 135TE Mig and im not sure how to change the feed roller so I can use diffrent wire sizes it has 3 diffrent groves but not sure how it comes off.
On the earlier models there is a little grub screw on the roller that needs to be slackened off. You simply then reverse it & tighten it up again, making sure the groove is in line with the wire.
The later models have a quick release type mechanism.
