Remedy
(1)Check if the voltage detection wire
is connected. Check to confirm that
the welding voltage sensing cable
select switch is set to "Base Metal".
The use of MOTOWELD-RP500:
Check to confirm that the voltage
sensing cable is connected between
the base metal and the terminal
block TB2 7.
The use of MOTOWELD-RL350/
X350:
Check to confirm that the base
metal-side welding voltage sensing
cable connects between the base
metal and the welding power source
via wire feeder cable.
(2)Check to confirm that the contact
chip and the welding work are not in
contact. Cancel the contact if any,
and weld them.
(3)Temporary power failure may
have occurred.
(4) When the welding voltage
sensing cable is used, please
connect the welding voltage sensing
cable to the base metal.
(5) When the AC unit used, a
weldingpower source output cable,
please?confirm whether the output
cable of the wiring of the AC unit is
not a mistake.
(6) When the AC unit used, please
make sure that the power of the AC
unit is turned on.
