R E ADY
(OUTP UT)
R eady P ower
The terminals used for ready power for prep. relay. When
there is not any error such as open phas e, Operation S top,
output over current, and thermal overload, the terminals work,
etc. while the power switch is on, the terminals function.

Operation S top
To stop welding externally. R elease the wiring between two
terminals to run Operation S top. Welding machine is s topped
by running Operation S top. C lose the terminals after turning
off the torch switch to restart welding. To avoid accidental
restart, use of a Push lock Turn reset switch is suggested.

(INP UT)
In case of there is the abnormal water pressure detection
relay in the cooling unit, which is like a pressure s witch,
remove the jumper wire on the terminal and connect the relay
contact. (C lose: normal Open: abnormal) T hen torch key in
the front panel is set “Water“ and contact is “Open” make E -

Terminal for
Direct
Detection of
Voltage
When using a power cable that is more than 30 m long, direct
connection of a direct detection wire of the base metal (-) to the
wire feeder is recommended, but it is imposs ible to connect to the
wire feeder due to jig, use the terminal block inside this welding
power source. R efer to S ection 10.2.1 (12) “Arc V oltage Direct
Detection ON/OF F S election” for details of direct detection.
P recaution for connection with terminals on the terminal block
The wires from the terminal blocks should be twisted for each signals to avoid accidental operation.
Take care that the wires form the terminal blocks do not cross other signal wires from other welding
power source.
*1 E quivalent circuit is as the figure shown right. Maximum capacity of TR is 80V , 100mA. When
connecting such as relay to two terminals, do not exceed 80% of the maximum capacity of T R .
(F igure 1)
*2 E quivalent circuit is as the figure shown right. C onnect allowable contacts (10mA or more) to two
terminals. (Figure 2)
*3 R ating of the provided relay contacts is 125V AC, 0.5A, 30V DC , 1A. Do not exceed 80% of the
rating of the provided relay contacts.
