: About filter at the air inlet fan
The air inlet fan at the side panels of the welding power
source unit is covered with a filter.
• Clean the filter periodically. And remove dust and/or
spatter attached to the filter. Using the controller with
clogged filter may degrade its cooling performance of the
fan, and performance of the robot will be deteriorated, as
a result, the “Temperature error” may occurs.
• In case of “Temperature error”(W1210, W1220), check
the filter and clean or replace it as necessary.
Adhesion of dust to the cooling fan of the built-in welding
power unit reduces cooling performance, which, as a
result, can cause the “Temperature error”. In that case,
clean the cooling fan.
(If the error recurs after cleaning the cooling fan, please
consult Panasonic representatives.)
How to replace filter
(1) Loosen the fixing screw of the filter fitting. Then
open the filter fitting and remove the filter.
(2) Insert a new filter into the filter fitting, and then
close the filter fitting. Then tighten the filter fitting
fixing screw.
