6.7.2.28 F38: Arc voltage direct detection switching
Sets the combination of enabling or disabling the voltage direct detection terminal on the base metal side of the welding
power source and voltage detection terminal of the wire feeder.
Extending the power cable without the cable at the base metal side can cause extraordinary volume of spatter. In this case,
setting this function to "1" by using the voltage detection cable (optionally available) can improve the status.

• 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".
6.7.2.29 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.
6.7.2.30 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.
6.7.2.31 F43: CAN ID
When multiple welding power sources are connected with a PC monitoring system, set ID for CAN.
