Remedy
(1)Check if the voltage detection
wire is connected.
The use of MOTOWELD-RP500/
EL350:
Check to confirm that the welding
voltage sensing cable or the short-
circuiting cap is connected to the
connector CON7.
The use of MOTOWELD welding
power source other than above:
Check to confirm that the welding
voltage sensing cable select switch is
set to "Base Metal".
(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
welding power 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.
