Remedy
When finish system reset, Shut
down the welding power source.
(1)Check if the output cable is short-
circuited or grounded.
(2) The power circuit may be
broken . Contact your YASKAWA
representative.
Confirm the following content.
(1) Check that the torch cable or
power cable is not grounded?
(2)Check that the contact tip does
not contact the welding work piece?
(3)Check that the encoder cable is
not damaged?
(4)Check if the screws of the
connector terminal block are
securely fastened. If the encoder
cable is disconnected or the screws
are loosened, the wire feeding speed
becomes excessively fast and an
error occurs in the wire feeding
amount. Replace the encoder cable
or fasten the screws of the connector
terminal block.
Confirm the input voltage.
(1)Check the ambient temperature
(40 degrees centigrade or less) and
operational ratio (60%).
(2) Check if there are dust, dirt, and
clogging on the dust protective filter.
Clean or replace the dust protective
filter if necessary.
(3)In case of RL350, Check the
thermal guard of primary side (Item
No.410).
In case of X350, Check the
thermal guard of primary side (Item
No.410).
