2. Maintenance of the Cooler Unit Section
2. Maintenance of the Cooler Unit Section
This section explains the maintenance of the coolant unit, including cleaning of
the solenoid valve filter, water drain of the primary cooling water and secondary
cooling water tanks, maintenance of the ion-exchanger, and water drain for the
case where the laser welder is not used for a long time.
Cleaning the Solenoid Valve Filter
The solenoid valve has a function to adjust the quantity of primary cooling water. If
the solenoid valve is clogged with dust, the primary cooling water is hard to flow,
thereby causing overheating. Perform cleaning for the solenoid valve once every
year as standard.
Item required
Brush, screwdriver, and bucket (container to receive water)
Operating Procedure
(1) Remove the solenoid valve cover
on the rear surface of the main unit
and pull out the solenoid valve.
(2) Turn off the primary cooling water
and disconnect the hose from the
cooling water inlet, and drain the
water.
⇒ Take care not to splash over the
Laser as water may spurt. If
water has splashed, wipe it off
completely.
(3) Remove the 4 body mounting
screws of the solenoid valve and
then remove the upper part of the
solenoid valve.
The part between the staffing
assembly and the gasket is
removed from the main body.
