Abstract
A programmable weld and machine controller for use in controlling a welding machine. The controller includes a central processing unit containing a stored control program connected to a memory which operates both the welding operation of the machine as well as the operation of the machine itself. The controller receives inputs from the machine in its various operational states as well as a data entry and display unit and a current monitor of the welding operation which generates outputs through a heat controlled output to activate a firing circuit to control the welding operation. Back-up of the memory program may be attained through an accessory port to a memory back-up storage unit.
Claims4
A programmable weld and machine controller for a machine having input and output devices and moveable through a sequence of operative states including welding operations on workpieces comprising:
- input means responsive to the input devices for indicating the state of the machine during operation;
- output means for controlling the output devices in operating the machine;
- a single memory means for storing a control program having a sequence portion and a programmable control portion, the memory means storing the status of the input means and the output means;
- a first portion of the memory means corresponding to the status of the input means and the output means being dedicated to the input means and the output means and controlled by the sequence portion of the control program;
- a second portion of the memory means being programmable by the sequence portion and the programmable control portion of the control program;
- and
- a single control processing means, responsive to the input means, the output means and the first and second portions of the memory means and executing a stored control program, for reading and setting the memory means and actuating the output means to control the operation of the machine in response to the sequence portion and the programmable control portion of the control program.
