NOTE
Connect welding power source and target device after carefully read the instruction manual
of target device. Add current limiting resistor if capacitor is connected to the contact of
target device.
If an ammeter is accidentally connected to the output-terminal for voltmeters, the ammeter
and/or the wiring will be burnt. Fully confirm to which the ammeter is to be connected.
When connecting a voltmeter and/or a voltmeter, be careful for short-circuit between the
positive wiring (+) and the negative wiring (-).
Input signal of the external connection terminal block
Use switches and relays with contact capacity of 24 V/10 mA or more for
connecting with the input terminal.
Output signal of the external connection terminal block
Output signal is open collector output. Ensure to keep the maximum
rated power of the transistor.
Maximum rated power of transistor
READY: DC50 V/100 mA
OUT EXT1 to 4: DC50 V/100 mA
WCR output signal
WCR signal is the output of relay contact. Ensure to keep the maximum
rated power of the contact.
Maximum rated power of relay contact
WCR: 125 VAC / 0.5 A, 30 VDC / 1 A at resistance load As a rough
indication, use at 80% of the ratings.
