6.2 TORCH MAINTENANCE

In reference to Fig. 7, the parts subject to wear are the
electrode A, the swirl ring B and the nozzle C; these must
be replaced after first unscrewing the gas nozzle holder D.
The electrode A must be replaced when it has a crater in
the center approximately 1.5 mm deep.
CAUTION: do not use sudden force to unscrew the elec-
trode; work gradually to release the thread. The new elec-
trode must be screwed into the seat and fastened in place
without tightening fully.
The nozzle C must be replaced when the central hole is
damaged or wider than that of a new part. Delays in repla-
cing the electrode or nozzle will cause the parts to
overheat, and jeopardize the life-span of the swirl ring B.
Make sure that the gas nozzle holder D is firmly tightened
after replacement.
CAUTION: Screw the gas nozzle holder D onto the torch
body only with the electrode A, swirl ring B and nozzle C
mounted.
If any of these parts are missing, this will interfere with
smooth operation of the machine and, especially, jeo-
pardize operator safety.

PRECAUTIONS AFTER REPAIRS.

After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and sec-
ondary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the orig-
