•
The wire feed speed with the maximum command voltage is 866 IPM (22 m/min).
(Depending on the welding mode, the wire feed speed does not always reach 866
IPM (22 m/min))
•
The minimum wire feed speed is approximately 24 to 79 IPM (0.6 to 2.0 m/min).
(This depends on the welding mode.) Even when a low command voltage is input, it
is not possible to set to a value below this.
•
[OFF]: disables the function.
–
The wire feed speed is automatically set based on the welding current.
–
Even when the welding mode is changed by the GAS menu, the wire feed speed is automatically set
based on the set welding current.
–
Each pressing the UNIT CHANGE key, the wire feed speed display and the welding current display
switches alternatively. Switch to the welding current display, and set the welding current in the unit
of 1 A.
–
Switching to the welding current display can check the wire feed speed automatically set.
–
In using the welding power source in the automatic machine mode, refer to the graph in " 6.7.2.4

6.7.2.21 F25 to F28: External output terminal setting
•
Through F25, you can set the functions of OUT-EXT1 ("3" – "4") on the terminal block for external connection.
•
Through F26, you can set the functions of OUT-EXT2 ("5" – "6") on the terminal block for external connection.
•
Through F27, you can set the functions of OUT-EXT3 ("7" – "8") on the terminal block for external connection.
•
Through F28, you can set the functions of OUT-EXT4 ("9" – "10") on the terminal block for external connection.
Configurable functions are as shown in the below table.
6.7.2.22 F29 to F32: External input terminal setting
Set the function of external input terminals. (when using robot or automatic machines)
•
F29: set the function of IN-EXT1 ("5" to "9") on the external connection terminal block TM3.
•
F30: set the function of IN-EXT2 ("6" to "9") on the external connection terminal block TM3.
•
F31: set the function of IN-EXT3 ("7" to "9") on the external connection terminal block TM3.
•
F32: set the function of IN-EXT4 ("8" to "9") on the external connection terminal block TM3.

Alarm Signal of Welding
Monitor
A welding condition error is detected during welding, and the signal is output to the external terminal.
If either of the current/voltage is out of the preset range, the external output terminal with this function
is closed.
