1. A system for providing an improved start in a welding process, the system comprising:

  • a power circuit for generating welding output power for a welding process; and

    a control circuit in communication with the power circuit to control the start of the welding process, the control circuit being configured to;

    receive a selection of a run in setting and a selection of a voltage;

    determine a start current pulse and a run time current pulse, wherein the start current pulse and run time current pulse each have peak magnitudes that are determined based on the run in setting and the selection of the voltage, wherein the peak magnitude of the start current pulse is determined according to the formula A+B*(the run in setting)+C*(the selection of the voltage), wherein A, B, and C are each amperage values;

    provide the start current pulse at a start of the welding process for a pre-determined period of time determined by the run-in setting and the selection of the voltage; and

    provide the run time current pulse after the pre-determined period of time has expired, wherein the run time current pulse is greater than the start current pulse.
