Turning feed roller
IMPORTANT Turn the feed roller to suit the wire size.
There are two grooves on the feed roller, 0.6mm and 0.8mm. Always have the groove that is being used on
the outside of the roller (nearest to you). To turn the feed roller first loosen the wire tension knob and move
it into its down position (see fig.10-1) then move the tensioning roller assembly to its up position (see fig.10-
2). Take hold of the triangular knob on the roller retainer and rotate it 0°anticlockwise to release it as shown
in fig.10.3. Now pull the roller retainer off the drive spindle to reveal the roller as shown in fig.11.
Pull the roller off the drive spindle, flip it over and put it back on the drive spindle. (See fig 12) The groove size
you require should now be visible on the face of the roller. Push the roller retainer back onto the drive spindle
with the opening facing left. Ensure that the flanges at the base of the retainer, seat fully into the circular recess
in the main molding and then rotate the retainer through 90° to lock it in place.

Replacing wire liner.
A worn or damaged wire liner will seriously affect the performance of the welder and should be immediately
replaced. First wind the wire back onto the spool and secure it. Remove the four screws securing the torch
cable clamp to the wire feed unit (fig.13) and take off the clamp. Undo the torch case (fig.14) and pull the
wire liner from the insulation block. Pull out the liner from the torch cable and insert the new one. Reverse
the process to re-assemble. Ensure the liner is fully inserted into the torch insulation block and reassemble
the torch. Trim the other end of the liner as close to the feed roller as possible. Replace the torch cable
clamp.

Replacing gears.
An inexperienced welder can allow spatter to build up in the tip and shroud. In severe cases this can block
the wire feed causing gear damage in the wire drive. To check if the gears are worn depress the button on
the torch with the set switched on. If the gears are worn, a grating sound will be heard coming from the wire
feed motor and you may also observe the feed roller vibrating instead of rotating smoothly. In this is the
case, return the welder to your local Sealey dealer for repair.
