Abstract
A method and apparatus for providing welding-type power includes a source of welding-type power and a controller. The controller is a state-based controller, and/or a deterministic control module, connected to the controller output. The state-based control module includes, in an embodiment, software instructions and a digital processor, and/or a state transition table stored in a spreadsheet data base. The controller is responsive to a feedback circuit. One or more welding peripherals, such as a wire feeder or robot, are connected to the controller. The current state may be represented by data in a first line of a spreadsheet and a state-ending event by a second, perpendicular, line of a spreadsheet. The subsequent state is determined by the intersection of the first and second lines in another embodiment.
