    Abstract: A method and apparatus for welding is disclosed. The output is preferably a cyclical CV MIG output, and each cycle is divided into segments. An output parameter is sampled a plurality of times within one or more of the segments. The CV output is controlled within the at least one segment in response to the sampling. The parameter is output power, a resistance of the load, an output current, an output voltage, or functions thereof in various embodiments. The control loop is preferably a PI or PID loop. The loop may be applied only within a window. The set point may be taught or fixed. The system can be used to weld with a controlled arc length.

    Abstract: The present invention includes a welding system that has at least two metal inert gas (MIG) welders configured to perform a cooperative pulsed MIG welding process. The welding system also includes at least one communications link connecting the at least two MIG welders to deliver at least one of subordination commands and superiority commands to either of the at least two MIG welders to synchronize the cooperative pulsed MIG welding process.
