6.7.2.22 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-EXT1("5"-"6") on the terminal block for external
connection.
Through F27, you can set the functions of OUT-EXT1("7"-"8") on the terminal block for external
connection.
Through F28, you can set the functions of OUT-EXT1("9"-"10") on the terminal block for external
connection.
6.7.2.23 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.

The functions allocable to F29 to F32 are as follows:
Setting
Function name
Explanation
0
-
No function is allocated.
1
Gas valve
Causing short circuit between terminals opens the gas valve. (*1)
2
Inching
Causing short circuit between terminals starts inching.
3
Retract
When inching operation is performed after short circuit is caused between terminals are
short-circuited, the wire feeding motor reverses to retract the wire. (*2)
4
Start
Causing short circuit between terminals starts welding. (torch switch: ON)(*3)
5
Loading welding
condition
The welding conditions stored on the memory can be read out by combination of signals.
(*4), (*5)
6
DC/PULSE switch
Short-circuit between terminals allows DC welding mode.
Open-circuit between terminals allows DC pulse welding mode.
Selecting optional "DC Wave Pulse" beforehand allows DC wave pulse welding mode.
Selecting optional "AC Pulse" beforehand allows AC pulse welding mode.
Selecting optional "AC Wave Pulse" beforehand allows AC wave pulse welding mode. (*6),
(*7)
7
WAVE PULSE/
PULSE switch
If "DC Pulse" or "DC Wave Pulse" has been selected, short-circuit between terminals allows
DC wave pulse welding mode.
Open-circuit between terminals allows DC pulse welding mode.
If "AC Pulse" or "AC Wave Pulse" has been selected, short-circuit between terminals allows
AC wave pulse welding mode.
Open-circuit between terminals allows AC pulse welding mode. (*6), (*7)
8
JOB shift +
Causing short circuit between terminals shifts to the following JOB No.. (*8), (*10)
9
JOB shift -
Causing short circuit between terminals shifts to the previous JOB No.. (*9), (*10)
*1: When the gas valve is opened by the signal from the external input terminal, the gas valve will not close when
welding completes or according to the timer (two minutes). In order to stop gas, ensure to open the terminals.
*2: Causing short circuit between the external input terminals before turning on the inching signal. To stop the
operation, turn off the inching signal and then disconnect the external input terminals.
*3: The starting terminal of the feeder receptacle on the front of welding power source becomes deactivated.
*4: Combination of the external input terminals enables to read out the welding conditions of the JOB No. 1 to 16
(Registration No. 1 to 16) registered on the memory. The corresponding JOB No. are as shown in the below table.
