Section III. Overview
Introduction
The front panel of the Power Supply contains the
Liquid Crystal Display
(
LCD
), and pushbutton
keys
(Weld Selector Keys, Numeric Keypad, and Operational Controls). Each is described in
Section IV,
Controls and Indicators
. The LCD and the front panel keys are used together when programming and
operating the Power Supply. Instructions on how to do this are in
Chapter 4, Operating Instructions.
The LCD displays all of the setup, programming, and operating information for the Power Supply. The
front panel keys allow you to enter data for programming custom weld schedules, customizing the
operating parameters of the Power Supply, and operating your welding equipment. The keys also allow
you to program the precise voltage, current, power, and time of each energy pulse into individual weld
schedules, which may contain one or two weld pulses. Weld schedules consist of:
•
Squeeze time before the weld pulse(s) [after the firing input is given]
•
The time and energy for each weld period
•
Cooling time between Pulse 1 and Pulse 2 [if two pulses are used]
•
Hold time after the welding pulse(s)
You can program and store up to 99 different weld schedules to meet a variety of welding applications.
