4. Explanation of Screens
4-11
(f) UPDN
The upper/lower limit waveform set on the Envelope setting screen is displayed in a
dotted line.
When CURR is made effective and UPDN is pressed, the upper/lower limit waveform
of the current is displayed.
When VOLT is made effective and UPDN is pressed, the upper/lower limit waveform
of the voltage is displayed.
* It is necessary to turn on “ENVELOPE” in 4. (11) (d) of the Monitor select screen.
(g) CURRENT
The monitor values of the WELD1/WELD2 welding current are displayed. The unit
is [A].
The displayed value is PEAK (maximum value) or RMS (effective value). For
selecting a display value, refer to “4. (6) (d) Measurement current select.” If the
upper/lower limit judgment of the monitor value of the welding current value results in
NG and if the envelope judgment results in NG, the background color of the unit is
changed.
(h) VOLTAGE
The monitor values of the WELD1/WELD2 welding voltage are displayed. The unit
is [V].
The displayed value is PEAK (maximum value) or RMS (effective value). For
selecting a display value, refer to “4. (6) (d) Measurement voltage select.” If the
upper/lower limit judgment of the monitor value of the welding voltage value results in
NG and if the envelope judgment results in NG, the background color of the unit is
changed.
(i) TIME
The WELD1/WELD2 weld time is displayed. The unit is [ms].
When the “Slope time” of the Monitor select screen is set to “Exclude”, only the time
of the pulse current section is displayed. For the “Slope time” item, refer to 4. (11)
(c) Slope time.” If the upper/lower limit judgment of the weld time results in NG, the
background color of the unit is changed.
(j) Screen display when the upper/lower limit judgment is NG
Red
When the monitor value exceeds the upper limit value (Set value on 4. (12) Upper/Lower
Limit Set Screen)
Blue
When the monitor value is lower the lower limit value (Set value on 4. (12) Upper/Lower
Limit Set Screen)
Orange
When the monitor value exceeds the upper limit of envelope (Set value on 4. (4) Envelope
Screen)
Purple
When the monitor value is lower than the lower limit of envelope (Set value on 4. (4)
Envelope Screen)
