If the liner becomes damaged or kinked,
it will be necessary to replace it.
Before commencing work, ensure the
gas and electrical supplies are
disconnected.
1.
Open the side cover, and
remove the welding wire from
the hose and torch assembly.
(Refer to ‘Installing Welding Wire’
on page 16).
2.
Slacken the three screws (W),
securing the Hose Support Bracket
Cover, slightly...do not remove.
RENEWING THE WIRE LINER
5.
Lift out the gas valve (F), and unscrew the liner (H) using a 5/16” spanner on nut (J).
6.
Straighten the hose assembly and pull the liner completely out of the hose.
7.
Thread the new liner into the hose from the torch end, so that it passes through the
Hose Support Bracket Assembly, then connect it to the gas valve and tighten.
8.
Reassemble the torch, taking care to ensure that the contact spring (E) and
the gas valve (F) are correctly seated. Note that a dowel is used to locate the
two halves of the handle. Ensure it is correctly lined up before tightening the
five securing screws.
9.
Pull the hose so that it is as straight as possible, and leave in this position whilst you
retighten the Hose Support Bracket Cover screws (W).
10. Replace the roller on the shaft, where it will butt up against the wire liner. Very
carefully, snip off the end of the liner so that a gap of approximately 2-3mm
max. exists between the end of the wire liner and the roller. There must be no
burrs which could impede the progress of the welding wire. Ensure you use a
sharp pair of snips.
11. Push the Roller fully home and secure with the securing knob.
3.
Remove the Roller (D)
4.
Holding the torch on its side on a flat
surface, carefully remove
the five securing screws,
and gently prise off the
uppermost cover, taking
care not to disturb the components within,
so that you can take note of the exact
manner in which they are located,
particularly the contact spring (E).
