4. Explanation of Screens
4-10
(4) Envelope Screen
To make the envelope function effective, turn on “ENVELOPE” in 4. (11) (d) of the Monitor select
screen. In this screen, the current reference waveform/voltage reference waveforms are obtained
for each condition No. and the upper/lower limit value from the reference waveform is set as
waveform data. There are two screens, namely, Envelope waveform check screen for a waveform
check and Envelope setting screen to set the upper/lower limit value for the waveform.

Envelope waveform check screen
* The full welding range is displayed on the Envelope waveform check screen.
(a) Welding result display
At the end of welding, the welding result judgment is displayed.
Normal GOOD: Lights in green.
Error NG: Lights in red.
When the monitor value is out of the upper/lower limit judgment range, the
judgment result in NG.
Accidental fire LOST:
Lights in red.
When the initial current cannot be detected or when a short-circuit
(contact) between a workpiece and the electrode cannot be recognized,
the judgment results in an accidental fire.
(b) SCH No
The condition number being set is displayed.
(c) Ready
The welding power supply ready ON/OFF status is displayed. (ON: Lights in green,
OFF: Does not light in green)
(d) CURR
The display (yellow lamp ON) or non-display (white lamp ON) of current waveform
can be selected. [Initial status: Display]
(e) VOLT
The display (red lamp ON) or non-display (white lamp ON) of voltage waveform can
