7.7. Replacing gears.
7.7.1. 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.
If this is the case, return the welder to your local Sealey dealer for
repair.

7.6. Replacing wire liner.
7.6.1. 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.
