•
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; (

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)
*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 (2 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.

The external input terminal without the setting "5" is regarded as signal OFF. Accordingly, for the function (external input terminal) which
does not require the "ON" status for the JOB No. to read can be set to other functions.
Example 1) In reading out the welding condition of the JOB No.3;
Setting F30 to "5" and turning the signal of external input terminal IN-EXT2 to ON enable to read out the JOB No. 3.
For F29, F31, and F32, other functions can be set.
Example 2) In reading out the welding condition of the JOB No.3;
Setting F29 to F32 to "5" and turning the signal of external input terminal IN-EXT2 to OFF enable to read out the JOB No. 3.
Example 3) In reading out the welding condition of the JOB No.7;
Setting F30 and F31 to "5" and turning the two signals of the external input terminal IN-EXT2/IN-EXT3 to ON enable to read out the JOB
No. 7. For F29 and F32, other functions can be set.
