SECTION 4:
OPERATION
4.01 Introduction
This section provides a description of the Power Supply
operating controls and procedures. Identification of the
Front and Rear Panel components is followed by operat-
ing procedures.
4.02 Functional Overview
The Weld Sequencer is designed to automatically control
the output of most solid-state power supplies. The Weld
Sequencer gives the operator more accurate control of the
variables within a welding operation. Once the Weld Se-
quencer is programmed for a particular welding opera-
tion, the weld can be reproduced with minimal fluctua-
tions. Four separate solid-state control modules, a Weld
Sequencer Enclosure and a RP1 Control remote pendant
make up the Weld Sequencer. Any combination of the
four modules can be used with the Weld Sequencer En-
closure to be a stand-alone unit.

1. ON/OFF Switch
Activates Weld Sequencer Enclosure power circuits
and supplies AC power to all Sequencer Controls in
ON position. In the OFF position deactivates all Se-
quencer Control circuits.
2. Red AC Power Light
Indicates that AC power is being supplied to the Se-
quencer control modules.
