Welding systems and sequence controllers therefor are presented for controlling components of a welding system during a welding operation. The sequence controller receives system inputs and provides control outputs to the system components, and includes a processing component, an executable sequence control program, and a state table file. The sequence control state table file includes a number of entries corresponding to welding operation states, where the individual entries comprise one or more instruction identifiers, instruction parameters, exit condition identifiers and corresponding next state identifiers. The sequence control program is executed according to the sequence controller inputs and according to the state table file to provide the sequence controller outputs, where the state table file can be easily modified or new state table files can be created and downloaded to the sequence controller to facilitate easy reconfiguration of a welding system. |
