the torch cable.
6.6.5 Insert the new liner into the torch cable and secure it in the wire drive unit by replacing the torch cable clamp. See fig.11. Insert the other end of the liner
through the locking ring and fully into the brass nut in the torch head. See 2 in fig.12.
6.6.6 Check that the torch inner parts are properly seated in their respective mouldings then close the torch by inserting the tongue on the switch moulding
(fig.12-5) into the slot at the front of the other moulding. Swing the switch moulding downwards and forwards until both parts have closed around the torch
cable. Slide the ribbed ring (fig.12-1) onto the end of the torch handle and turn it clockwise to lock.
