OFF/Off
time and
WELD COUNT
do not work simultaneously. When
WELD COUNT
is set, OFF is invalid.
b. NO CURRENT TIME
The absence of welding current will not be detected as a no-current or no-voltage error (see
Chapter 5, Troubleshooting
) as long as the absence lasts for a period within the time set here.
For example, if you select 3ms, the absence of current will not be detected as an error as long as
it lasts no more than 3ms. An absence of current will be detected as an error if it lasts for 4ms or
more.
At this time, the
TROUBLE
lamp lights up. When the Pendant is connected, the fault code is
displayed on the monitor.
COOL

INT
times are not included in the time for
the no-current to be detected.
c. NO CURRENT LEVEL / d. NO VOLTAGE LEVEL
Set the current or voltage level for determining the absence of current or voltage as a no-current
or no-voltage error. The
TROUBLE
lamp will light up, and operation will stop if the monitored
current or voltage falls below the level set here.
In the case of primary current control, supplying current with the welding transformer’s
secondary side open will cause an excitation current to flow through the primary side. Set the
current level slightly higher than the monitored current.
NOTE: No judgment as to no-current or no-voltage error will be made if you select
00.0kA/0.00
V
. If the toroidal coil and the voltage detecting cable are disconnected in the second control,
excessive current may flow.
e. MONITOR FIRST TIME
Use this setting to specify the start time to measure the monitored value (current, voltage, power,
pulse width). The start time can be set in a range from 0 to 15ms. Use this setting to exclude the
initial rise of current from measurement.
The monitored value will not be displayed if the weld time is shorter than
MONITOR FIRST
TIME
. The monitored value will not be also checked against the upper and lower tolerance limits.
