CONDUIT IDENTIFICATION AND REPLACEMENT

The procedure for removal and installation of a wire conduit is similar for all Tweco MIG guns. Conduits
may be identified by the type of conduit stop and the part number marking on each conduit stop.
Example Part Number:
Conduit Removal
1. Lay the MIG gun out on a table or on the floor in a straight line. Make sure the gun is
fully extended and all twists in the cable are removed.
2. Remove the nozzle and tip.
On Miller Direct Plug MIG guns, remove the nipple on the end of the connector
®
plug. On Euro-Kwik connections, remove the conduit retaining cap.
3. Loosen the conduit set screw in the front of the gun. This is usually located at the
front of the handle. Then loosen the conduit set screw in the rear connector plug.
4. Grip the conduit stop and remove the conduit with a twisting motion. On Miller
Plug MIG guns, twisting the rear of the gun approximately one revolution clockwise
will raise the conduit stop out of the connector plug recess.
Conduit Installation - Velocity Contact Tip Style
Failure to follow Conduit Installation Instructions will cause wire feed issues.
1. Uncoil the conduit and lay it in a straight line. Insert the conduit into the rear connector plug.
Push the conduit into the gun with short strokes.
If the conduit hangs up gently whip the cable while applying pressure to the
conduit. New liners must be cut to the correct length.
2. When the conduit is completely in the gun, tighten the rear conduit set screw. On Miller
guns, reinstall the nipple. On Euro-Kwik guns, reinstall the conduit retaining cap.
