• [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 key, the wire feed speed is automatically set
based on the set welding current.
– Each pressing the CURRENT SETTING DISPLAY SWITCH 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 " 6.7.2.3
-
F5:
Maximum external command voltage". (When the internal function F4 (Auto/Semi-auto mode) is
used with the setting of Automatic machine 1 mode)
6.7.2.21 F25 to F28: External output terminal setting (reserved)
The external output terminals (OUT-EXT1 to EXT4 on the external output terminal TM4) are used in
connection with the automatic machines of other manufacturers.
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.
For the details of external connection terminal block; ( 4.5.2

Connection of automatic machine)
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. (*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. (*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.
