6.3.1 Jig terminals
Note
•
Remove the shorting bar before using the terminals if inserted.
Otherwise, the terminals won’t function.
•
Connect the start signal of the welding power source to the
torch switch outlet of the wire feeder.
•
Voltmeter and ammeter terminals are directly connected to the
output circuit of the welding power source. Connect instruments
with caution, such as electrical insulation from circuit of other
devices, grounding fault, short-circuit protection and noise
contamination prevention in mind.

STOP1
STOP2
Open the terminals to bring the welding power
source to a temporary stop. At that time, gas check,
wire inching and wire retract functions as well as
welding output, gas supply and wire feed functions
stop.
•
STOP 1:Connect a signal, such as gas pressure drop
detection signal.
•
STOP 2:Connect a signal, such as low water detect
signal when water cooled torch is used.
<How to reset> Close the terminals
•
Voltage when terminal is open:
24 V DC
•
Current when terminal is closed:
10 mA DC
•
Use a signal free from contact fail-
ure to connect to each terminal.
EMER-
GENCY
STOP
Open the terminals to bring the welding power
source to an emergency stop. At that time, welding
output, gas supply and wire feed functions are
stopped.
<How to reset> Turn the power switch OFF and close
the terminals, and then turn the power switch back
ON again.

OUTPUT
Use it when the contact output of the management
function is set to Valid. See section “
Rated output (at resistance load)
Load voltage: 60 V DC
Load current: 0.6 A DC
•
Do not exceed the above ratings.
•
Do not use alternate current (AC)
CUR.
DETECT
It closes while flowing welding current.
Use it to synchronize the welding current state with
an external device.
GAS CHECK
Close the terminals with a non-voltage contact, such
as push button, to activate the gas supply solenoid
valve of the wire feeder.
Required capacity of the contact:
30 V DC /1 A or larger
VOLTMETER
It is to connect a DC voltmeter to display output volt-
age.
Voltmeter type: displays 100 VDC or
larger values.
AMMETER
It is to connect a DC ammeter to display output cur-
rent.
Ammeter type: an exterior type DC
ammeter connectable to a shunt
(60 mV DC/600 A DC).
*This product has a built-in shunt.
For the size of the cable to connect to
the ammeter, use one specified by the
manufacturer of the instrument.
