• Use the voltage detection cable (optionally available) when the total length of the extension cable is
99 ft (30 m) or longer.
• When using wire feeder CM-7403, water-cooled welding torch cannot be used. Accordingly, arc voltage
direct detection switch cannot be activated even with this function set to "1".
• When using a reverse-polarity wire, set this function to "2".
6.7.2.28 F39/F40: Output current gain adjustment
If there is difference between the current value indicated on the digital meter and the actual output current value, the
difference can be calibrated through adjustment of F39/F40.
The output current value that can be changed by F39 is [1], which is equivalent to 1A. The value that can be changed by
F40 is about 0.01A, which is equivalent to [0.01].
This function can be adjusted only in the "calibration mode". For details, refer to "7.6
-
Calibration Mode".
NOTE
• Do not carelessly change the setting of this function.
6.7.2.29 F41/F42: Output voltage gain adjustment
If there is difference between the voltage value indicated on the digital meter and the actual output voltage value, the
difference can be calibrated through adjustment of F41/F42. The output voltage value that can be changed by F41 is [0.1],
which is equivalent to about 0.01 V. The value that can be changed by F42 is about [0.01], which is equivalent to about 0.01
V. This function can be adjusted only in the "calibration mode". For details, refer to "7.6
-
Calibration Mode".
NOTE
• Do not carelessly change the setting of this function.
6.7.2.30 F43: CAN ID
When multiple welding power sources are connected with a PC monitoring system, set ID for CAN.
6.7.2.31 F44: Reading welding conditions with remote control
Sets whether to read the welding condition registered to the memory by the analog remote control (optional) or not. This
function is effective when the internal function F4 (Auto/Semi-auto mode) is set to "0".
•
[ON]: reads the welding condition by the analog remote control (optional)
–
Setting the welding current setting knob on the analog remote control to 1-10 of the scale can read out the
conditions stored to the JOB No. 1-10.
–
By the welding voltage setting knob, fine adjustment of the welding voltage of the condition read out is available.
(% adjustment)
Adjust the voltage value based on the center of welding voltage setting knob. To increase the welding voltage,
turn the knob clockwise and to reduce the welding voltage, turn the knob counterclockwise.
The fine adjustment range for welding voltage is up to ±20 %.
Example:
The right figure shows an example when the JOB No. "3" is read out and the
welding voltage is the condition stored on the memory (no fine
adjustment).
