Abstract
A method and system for controlling a welding cycle of an arc welder comprising: a number of digital programs stored in a digital memory device, with each of the programs including a plurality of digitally coded welding parameters indicative of selected functions of a specific welding cycle; a weld controller for converting the selected functions of a digital program into welding parameters at the output of the welder; a display panel having a group of switches located in a given pattern and a decoder network at a selected position for creating a decoded signal indicative of the activation pattern of the decoder network; means responsive to the decoded signal for activating said switches in either a first condition where the switches activate means for modifying a selected one of said digital programs or a second condition where said switches activate means for creating a program select signal corresponding to a given digital program; means responsive to a program select signal for selecting one of the programs corresponding to the program select signal; and, loading means for loading a selected one of the programs into the weld controller for controlling the welding parameters of …
