(Note) Current flow waiting time of 500 ms
The current flow waiting time of 500 ms used for impulse measurement is the
time after b + c + d.
When the current flow interval is longer than the time of b + c + d + e, a
measurement is made as another sequence.
a: WELD (weld time of the welding power supply)
b: Time until the current falls below the END LEVEL setting
c: Time set in COOL TIME
d: 0.5 CYC when TIME is CYC, 1 ms when TIME is ms
e: Current flow waiting time of 500 ms
2-1) When current is first measured, and displacement, force or external input
is NOT measured
The step set in PULSE No. is measured.
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.
a: WELD b: COOL, less than 500 ms
c: Interval between welding sequences, more than 500 ms
d: Current flow waiting time of 500 ms
When PULSE No. is set to 2, the second step is measured. 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.”
2-2) When current is first measured, and displacement, force or external input
is measured
The step set in PULSE No. is measured.
Before the specified step is measured, 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, the impulse error occurs. After the specified step is
measured, when the interval of the several current flows is shorter than the
setting of FINAL DELAY TIME of DISPLACEMENT, DELAY TIME of FORCE,
or DELAY TIME of EXTERNAL, a measurement is made as a single sequence.
When the delay time elapses, a measurement is made as another sequence.
A single welding sequence is measured as a single sequence. When the delay
time elapses, a measurement is made as another sequence.
