set to “Exclude”, the waveform including the slope is displayed.

* When the welding monitor value is “0”, no waveform is displayed.
* When modulation is set, the modulation ON/OFF waveform is not displayed on the
reference waveform. The welding monitor waveform may be different from the
actual waveform because of data sampling and modulation frequency.
* Only when the drive setting of the touch start is “MOTOR”, and the initial current
time is set to 0 ms, the auto mode or fine weld mode can be selected.
At this time, the initial current time of the reference waveform on the Monitor screen
is displayed by adding the fixed time 500 ms (*1). Set conditions such as moving
speed and moving distance of the torch head so that the torch head can move to the
main welding start position within 500 ms.
If the main welding start signal H-ST2 is not input from the torch head controller
within 500 ms, “E18 Start2 - time limit exceeded” will occur.
Since the current and voltage monitor waveform is displayed in the actual time, it is
displayed in front of the set current waveform.
*1: In the auto mode or fine weld mode, the initial current time of the reference
waveform on the Monitor screen is fixed to 500 ms since the initial current time
fluctuates depending on the torch head rising speed or the moving distance and
the initial current time cannot be known before welding.
(n) ENVEL
Used to go to the Envelope screen.
(o) Waveform display
The waveform can be displayed by pressing the portion close to the “MONITOR”
display in the upper left part of the screen. Even if the setting of “4. (6) (h) High
speed SCH change (No Wave)” is made effective, the waveform is displayed. To
check the waveform at welding NG, press this switch.
