Draining Water from the Primary Cooling Water
When the laser welder must be moved or transferred or its operation is stopped over
one month, drain the primary cooling water.
⇒ For changing the ion-exchange resin for repacking, changing the ion-exchanger,
changing the water filter, and changing the secondary cooling water, the primary
cooling water does not need to be drained.
⇒
For the primary cooling water, use tap water or clean industrial water.
Item required
Water feed pump and bucket (container to receive water)
Operating Procedure
(1) Remove the 2 hoses connected from the outside and drain water.
⇒
Sometimes, water may spout out hard. Take care not to splash water on the
laser welder. If the laser welder is splashed with water, wipe it off completely with
a cloth.
(2) Connect both of the cooling water inlet and outlet with a hose as shown.
