EXTENDED FUNCTIONS
Selector Switch 10 (SIMPLE UNIFIED/INDIVIDUAL) --- Set to INDIVIDUAL upon shipment
INDIVIDUAL --- This mode sets both welding current and voltage to INDIVIDUAL.
SIMPLE UNIFIED --- When a welding current is selected with the output regulator on
the remote controller, the SIMPLE UNIFIED mode takes place ,where
an almost corresponding welding voltage is automatically set. When
an optimum voltage or desired voltage has not been set, make
adjustment with the
”
voltage fine control VR.
”
Note) For individual/simple unified output adjustment, the front and back
of the scale plate on the remote controller are available.
For simple unification, reverse the scale plate.
When a special wire or flux cored wire is used, stable welding conditions may differ from
simple unification conditions depending on wire types or brands, and may not be adjusted within
a range of welding voltage fine adjustment.
In this case, switching to "INDIVIDUAL" allows optional setting of the welding voltage to
widen an adjustment width.

Connector 9(CN9): Current Detection Contact Terminal
A portion between the two pins or the connector 9(CN9) is connected to a relay's
ever-open contact(contact-a) on the printed circuit board.
When it is confirmed that the welding current has flowed (current detection), the
contact is closed and kept closed while the welding current is flowing.
When providing external control with this current detection contact, cut a loop-shaped
vinyl wire above the connector and use those two wires as lead-out wires.
A relay contact capacity is 30 V DC. 2 A or 125 V AC. 0.5 A, depending on resistance
load conditions. The circuit should be configured so that this allowable current value
will not be exceeded in use.
