Abstract: A method and apparatus for providing welding-type power including a source of welding-type power connected to a controller is disclosed. The controller includes a controller network module with a controller multiple level message module. A welding-type device includes a device network module with a device multiple level message module. A network is operatively connected to the network modules, and is capable of sending a plurality of multiple level messages. A welding peripheral and/or a second source of power has a network module with a multiple level module and is connected to the network. The multiple level message includes an identifier portion and a data portion, and the data portion can include a pointer portion and a value portion in various alternatives. The components may have memory connected to the multiple level message modules, and store common message decoding data therein so that they have shared knowledge for decoding the pointer portions and data portions.

Abstract: A method and apparatus for calibrating a welding-type power supply and a robot are disclosed. They include entering a calibration mode (in the welding-type power supply) and providing one or two predetermined commands (for a welding parameter) from the robot to the welding-type power supply, and comparing them to two standards. A command scaling curve for the parameter is calculated in response to the comparisons. Predetermined commands, relating to two or more different welding parameters, may be used to calibrate two or more parameters, and to create two or more command scaling curves. Parameters that are calibrated include wire feed speed, voltage and arc length (trim). Feedback from the welding-type power supply may be provided to the robot that is indicative of a commanded output. The predetermined commands may alternatively be user-determined, or provided by a user interface or a memory.
