Stopping the Operation
(1) Put the section between pin No.18 of the EXT.I/O (1) connector and COM in an
open circuit to cut off the high voltage.
(2) Put pin No.23 (control switching) of the EXT.I/O (1) connector in an open circuit
to invalidate external input signals
Making a Position Adjustment by Guide Light
Make a position adjustment by guide light before welding according to the
following procedure.
(1) Adjust the workpiece and output unit positions to set an appropriate work
distance (distance between the workpiece and the output position).
(2) Put the section between pin No.22 of the EXT.I/O (1) connector and COM in a
closed circuit.
Guide light can be seen as a red point. Laser light is irradiated to this red point
position.
(3) Check the laser light irradiation position.
If the welding point deviates from the red point of guide light, move the output
unit or workpiece to adjust the position.
