release the trigger, switch off the machine and disconnect from the mains
supply. Replace the contact tip and the torch shroud.

is fed through to the wire liner and torch.

Unscrew and remove the torch
shroud by twisting it anti clockwise,
then unscrew the contact tip.
Should any wire protrude from the
tip....pull it out completely and
discard.
D. Selecting the Correct Drive Roller Groove
As previously mentioned, it is important that the correct groove in the drive roller is
selected for the particular wire being used. Two grooves, 7mm and 8mm are

To change to the other groove, proceed as follows:
1. With the pressure roller bracket
raised, and the old wire removed, as
shown, turn the roller securing knob
(A), fully anticlockwise, as indicated
in Fig.7, and pull it from the shaft,
followed by the roller.
2. Turn the roller through 180

it on the shaft, followed by the
securing knob, which should then
be turned fully clockwise to lock the
roller securely in place.
