4. Explanation of Screens
4-8
Red
When the monitor value exceeds the upper limit value (Set value on the Upper/lower
limit set screen in 4. (12))
Blue
When the monitor value is lower than the lower limit value (Set value on the
Upper/lower limit set screen in 4. (12))
(i) VOLTAGE
The monitor values of WELD1 and WELD2 welding voltages are displayed. The unit
is [V]. The displayed value is PEAK (maximum value or RMS (effective value). For
selection of a display value, refer to “4. (6) (e) Measurement voltage select.” If the
upper/lower limit judgment for the monitor value of welding voltage value results in
NG, the background color of the unit is changed.
Red
When the monitor value exceeds the upper limit value (Set value on the Upper/lower
limit set screen in 4. (12))
Blue
When the monitor value is lower than the lower limit value (Set value on the
Upper/lower limit set screen in 4. (12))
(j) TIME
The WELD1 and WELD2 weld times are displayed. The unit is [ms].
When the “Slope time” item of the Monitor selection screen is set to “Exclude”, only
the time of pulse current section is displayed. For the “Slope” item, refer to “4. (11)
(c) Slope time.” The initial current time and the cooling time are displayed at the
reference waveform set on the Welding condition setting screen, but the initial current
time and the cooling time are not included in the displayed time in TIME. When the
upper/lower limit judgment of the weld time results in NG, the background color of the
unit is changed.
(Screen display when the upper/lower limit judgment is NG)
Red
When the monitor value exceeds the upper limit value (Set value on the Upper/lower
limit set screen in 4. (12))
Blue
When the monitor value is lower than the lower limit value (Set value on the
Upper/lower limit set screen in 4. (12))
(k) ALL
COUNT
Becomes valid when any value other than 0 is set to PRE COUNT. At each welding,
+1 is added regardless of the welding judgment (GOOD/NG/LOST) (for all SCHs).
For clearing a counter value, refer to “4. (6)
(j) ALL WELD COUNT Clear.”
(l) PRE
COUNT
When this switch is touched, PRE COUNT can be set. The setting range is 0 ~
999999. If the ALL COUNT value exceeds the PRE COUNT value, “E06 End of
counter reached” occurs. If the set value is 0, the ALL COUNT function becomes
invalid.
(m) Waveform display area
The welding monitor waveform based on the last welding condition No. and the
reference waveform created from the data set on the Welding condition setting
