ROUBLESHOOTING

HAPTER

There are blowholes.

There is a problem in the
shielding gas.

Check that there is no abnormality in the gas
cylinder or gas hose.

The chip of the welding torch
wore out.

Replace the chip.

Continuous output of the WCR
signal is shown on the monitor
of the robot.
(The WCR signal is used for
communicating with the robot to
check the presence of the
welding current.)

The WCR relay of welding power
source is broken.

The WCR relay on the printed circuit board PCB1
(P30099P00) needs to be replaced.
