• ALL PULSE (NO SET)
Used when current is passed several times in a single welding sequence,
but the number is not decided.
PULSE No. is not used. When the interval of the several current flows is less
than 500 ms, a measurement is made as a single sequence. When 500 ms
elapses, a measurement is made as another sequence
The measurement schedule and judgment schedule are the same as those of
ALL PULSE (SET). Set the maximum number of current flow times.
(Note) For the current flow waiting time of 500 ms, refer to “･SET PULSE,
(Note) Current flow waiting time of 500 ms”.
1) When current is first measured, and displacement, force or external input is
NOT measured
a: WELD b: COOL, less than 500 ms
c: Interval between welding sequences, 500 ms or more
d: Current flow waiting time of 500 ms
In the 3-step welding, the first to third steps are measured and then ended. In
the 4-step welding, the first to fourth steps are measured and then ended.
When 500 ms elapses, a measurement of a single sequence ends.
(Note) For measurable time, refer to “Measurable time of all-pulse
measurement for each mode.”
2) When current is first measured, and displacement, force or external input is
measured
a: WELD b: COOL, less than 500 ms
c: Interval between welding sequences, 500 ms or more
d: Current flow waiting time of 500 ms e: Delay time
In the 3-step welding, the first to third steps and DIST FINAL, FORCE FINAL
or EXT FINAL after the delay time are measured and then ended. In the 4-step
welding, the first to fourth steps and DIST FINAL, FORCE FINAL or EXT
FINAL after the delay time are measured and then ended. When 500 ms
elapses, a measurement of a single sequence ends.
(Note) For measurable time, refer to “Measurable time of all-pulse
measurement for each mode.”
