1. A method of controlling a short circuit welding process, comprising:
setting a heat target for at least a portion of a short state;
monitoring output parameters during the short state;
calculating a measured heat from the measured output parameters;
comparing the measured heat and the heat target;
adjusting, via a controller, a pinch current in a subsequent short state in response to at least one comparing from at least one previous short state; and
repeating these actions.
