5.2. TORCH MAINTENANCE

Replacement of consumable parts
The parts subject to wear are electrode 23, diffuser 24 and
nozzle 25. All parts may be only replaced after loosening
nozzle holder 26. Electrode 23 should be replaced when a
1/16" (1,5 mm) deep crater is created in the middle. Nozzle
25 should be replaced when its central hole is damaged or
enlarged in comparison with the new part.
The use of a worn electrode quickly wears out the nozzle.
When the electrode is worn, the power cut of the machine
is reduced. A delayed replacement of electrode and nozzle
causes overheating of consumable parts and reduces the
life of diffuser 24. Make sure that after replacing it, nozzle
holder 26 is tight enough.
ATTENTION! Nozzle holder 26 should be screwed on
head only when electrode 23, diffuser 24 and nozzle 25
are assembled.

5.3. PRECAUTIONS AFTER REPAIRS

After making repairs, take care to organize the wiring so
that there is secure insulation between the primary and
secondary 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 original machine, to prevent a connection from
occurring between the primary and secondary circuits
should a wire accidentally break or be disconnected.
Also mount the screws with geared washers as on the
original machine.
