7.5 TRIGGER ELECTRODE
7.5.1 Replacement Method
(1) Turn off the power to the CNC, then turn off the main circuit
breaker and power supply for the laser oscillator.
(2) Remove the cable connected to the trigger electrode.
(3) The mounting screw of the trigger electrode is made of plastic.
With a 3-mm non-ball-point hexagonal wrench, remove the
screw. If the screw head is damaged, use needle-nose pliers to
loosen the screw.
(4) Replace the O-ring with a new one, and mount a new trigger
electrode with the attached screw. If the O-ring or plastic screw
is damaged, replace it. Never use a metal screw.
Item Specification
1 O-ring JB-OR4D-P10
2 Plastic screw A98L-0004-0801#4-15
(5) Tighten the plastic bolt with a tightening torque of 0.5 N⋅m. If
you cannot prepare a torque wrench, use a small L wrench (64
mm × 23 mm). Hold the shorter side, and tighten the bolt as far
as you do not feel a pain in your fingers. Use a wrench having a
hexagonal end; never use a ball-point type wrench.
(6) After the replacement, start the oscillator, check for leakage, and
perform discharge aging.
