10. OPERATION
(Continued)
10.1.9 Using the Parameter Adjusting Knob
When using CURRENT and VOLTAGE adjusting knobs ([4] and [5]) to adjust parameters during
welding, change over the display mode to the “parameter setting value display” mode by
pressing the DISPLAY CHANGE key [7] . The INITIAL conditions, the MAIN conditions, and the
CRATER conditions can be changed during the INITIAL welding, MAIN welding, and CRATER
welding respectively. Pressing the ARC CONTROL key[8] after changing to the “parameter
setting value display” mode adjusts the arc characteristics.
10.1.10 Verifying the Parameters in the Display
The display on the front panel provides the following functions:
1) Display of Parameter Setting Values
When setting to “parameter setting values display” mode during intermission period, or in
the “setting value display” mode set during welding, parameters setting value can be
displayed.
2) Display of Output Current and Voltage During Welding
The parameters shown in the displays automatically change to average values of output
current and output voltage according to the output conditions every about 0.5 seconds.
When you want to change the parameters during welding, press the DISPLAY CHANGE
key[7] to go to the “parameter setting values display” mode. When no welding operation is
carried out for about 5 seconds or the DISPLAY CHANGE key[7] is held down, the display
mode automatically returns to the “average parameter setting values display" mode. To
adjust parameters during welding, press DISPLAY CHANGE key[7] to switch to the “setting
value display” mode. If neither any operation is done nor DISPLAY CHANGE key[7] is
pressed within 5 seconds, the digital meters will automatically return to the “average value
display” mode. When pressing the welding torch switch, the LEDs in the part of welding
parameter setting will light up according to welding operation and will switch in sequence.
When switching to the “average value display” mode, the LED in the part of welding process
parameter setting, which is having an output, will blink.
3) Display of Welding Results After Completion of Welding
After completion of welding, the average output current and voltage of the last one second
blink for about 20 seconds (however, the output condition of crater filler are ignored). The
welding operator can verify the welding conditions according to such display after
completion of welding, and such results can also be used as approximate values for
condition adjustment. Such display can be canceled after completion of welding by starting
another welding or by pressing any key on the control panel without the 20 seconds delay.
The result display time can be set by internal function “F8”, wherein the left digital meter
displays setting value and the “sec” LED lights up. The setting range for the result display
time is 0–60 seconds.
NOTE: In the case where the less than one-second welding such as tack welding, etc.
is performed, the correct results of the welding are not displayed.
4) Display of an Abnormality When It Occurs
If an error is detected in the power source, an error number indicating error message blinks.
See Section“12.4 How to Solve an Error ”for details.
NOTE: The average output current and voltage displayed by the digital meters are for
reference only, and it is not guaranteed that they can be used as metering
management data.
