Select a correct welding process in the using the welding user file.
If the alarm occurs again, save the CMOS.BIN in maintenance mode,
and then contact your Yaskawa representative about occurrence
status (operating procedure).
(1)Check if the voltage detection wire is connected. Heck if the voltage
detection line or the short-circuit cap is connected to the CON7 of the
MOTOWELD.
(2)Check that the contact tip does not contact the work piece to be
welded. Set the contact tip so as not to contact the work piece.
(3)Temporary power failure may have occurred.
