MAWA-050A
4. Explanation of Screens
4-7
Remarks
There is a difference in the waveform display range between when the “WELD1” and
“WELD2” magnified display is selected and when “FULL” is selected. In the time
display in the lower part of the graph, each weld time of “WELD1” and “WELD2” is
displayed when the magnified display is selected. In the time display in the left/right
part at waveform magnification, the left numeric value represents a start point of
welding waveform, the center value represents the medium position of welding
waveform, and the right numeric value represents the end point of welding waveform.
When “FULL” is selected, the entire weld time (including the initial current section and
cooling section) is displayed.
(2) CURR RANGE [A]
The display range of current waveform can be changed.
It can be selected among 60 [A], 30 [A] and 12 [A].
(3) VOL RANGE [V]
The display range of voltage waveform can be changed.
It can be selected among 50 [V], 25 [V] and 10 [V].
(h) CURRENT
The monitor values of WELD1 and WELD2 welding currents are displayed. The unit
is [A]. The displayed value is PEAK (maximum value) or RMS (effective value).
For selection of a display value, refer to “4. (6) (d) Measurement current select.” If
the upper/lower limit judgment for the monitor value of welding current value results in
NG, the background color of the unit is changed.
The selected current range is displayed. (Yellow lamp ON)
