摘要： 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.

摘要： A short circuit arc welding system is disclosed. The control scheme uses a current command signal comprised of a long-term current command that sets the long-term current command level and a real-time or short-by-short current command to drive the output current. Feedback is used to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command is derived from real-time arc current feedback and is used to control the burn-off rate by adjustment of the current command. The short being about to clear is detected in real time. When the process is ending a very low current level is provided to avoid forming a ball. If a short is created, after the low current level, a burst of energy is provided to clear of burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball, until the wire stops and the process ends.

摘要： A short circuit arc welding system is disclosed. The control scheme uses a current command signal to drive the output current. The command signal is comprised of a long-term current command that sets the long-term current command level and a real-time or short-by-short current command. Arc voltage feedback is used to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command is derived from real-time arc current feedback and is used to control the burn-off rate by an instantaneous, or short-by-short, adjustment of the current command. A function of the time derivative of arc power, less the time derivative of arc current, is used to detect, in real time, when the short is about to clear. A stop algorithm is employed that monitors the arc on a short-by-short basis. When the process is ending a very low current level is provided to avoid forming a ball. However, if a short is created, (indicated by a drop in arc voltage) after the low current level, a burst of energy is provided to clear of burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball. This is repeated until the wire stops and the process ends.
