2. Maintenance of the Cooler Unit Section
This section explains the maintenance of the coolant unit, including cleaning
of the solenoid valve strainer, 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 Strainer
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, 10-mm and 17-mm spanners, 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 fixing screws
of the solenoid valve and then
remove the upper part of the
solenoid valve. Then, pull out
the spring and diaphragm.
(4) Take out the strainer and wash
out the dust with which the
mesh is clogged.
(5) Return the strainer into the
initial status and install the
diaphragm, spring, and upper
part of the solenoid valve.
Tighten the solenoid valve with
the fixing screws (4 screws).
