To switch higher DC currents, either relay can be removed from its socket and reinserted two positions
to the right. Maximum relay current is limited to 1.0 amps. Polarity must now be observed.
CONTROL SIGNAL OUTPUT Connector
When the control signal output cable is connected between this connector and the CONTROL SIGNALS
connector on the HF2 or HF25 Power Supply, selecting a new schedule on the Weld Head Control
automatically selects the identical schedule number on the power supply. On the UB25 Power Supply, the
schedule must be separately set on the power supply See table B-2 for the connector pin assignments.
