MONITOR FIRST TIME
MONITOR FIRST TIME
sets the time to begin the measurement of monitored
value (current, voltage, wattage, and pulse width). Setting range is 1-15ms.
This function is used to exclude the initial slope from the measurement. When
the welding time is shorter than MONITOR FIRST TIME, although a monitor
value is indicated, the judgment of a monitor value is not performed.
In
IS-120B-00
and
IS-120B-02
, the current during
UP SLOPE
and
DOWN SLOPE
is also monitored in the control methods excluding
the
Primary constant-current peak value control.
So, if the set period in
UP SLOPE
and
DOWN SLOPE
is longer than
MONITOR FIRST TIME
, the monitored current may be displayed less
than the set value.
In the Primary constant-current peak value control
of
IS-120B-00
and
IS-120B-02
and all control methods of
IS-120B-03
,
no current during
UP SLOPE
and
DOWN SLOPE
is monitored. In the occasion, if the
period of
WELD1
and
WELD2
is equally set to the period of
UP SLOPE
and
DOWN SLOPE
, the monitored value is displayed as “0”.
