Contact Output Circuit
Five contact output circuits (4 welding power source specific outputs
(arc-ON, wire inching, wire retract inching, starting point detection
command (optional function)), and 1 universal output) are available
.

1 This is a maximum value in the case of the resistive load. Maximum rate
differs depending on the type of the load (AC/DC, resistive/inductive/capacity
load). Relay contact sticking, and open-close life reduction may occur. When
connecting the inductive load, install elements such as flywheel diode on the
load side. In the case of using I/O current (+24 VU), maximum of approx.
500 mA can be taken out (fuses F1, F2 may blow out when the current
exceeds the above limit).
