Systems and methods to control pulse welding

A welding-type system, comprising:

• power conversion circuitry configured to convert input power to welding-type power;
• and
• control circuitry configured to control the power conversion circuitry to output the welding-type power in a plurality of pulse cycles, each pulse cycle comprising a background phase, a ramp up phase, a peak phase, and a ramp down phase, wherein the controlling the power conversion circuitry comprises:
• during the ramp up phase of the pulse cycles, controlling the power conversion circuitry in a current-controlled mode based on comparing an output current of the power conversion circuitry to a target current while ramping up the target current;
• in response to reaching a peak transition voltage, switching to controlling the power conversion circuitry during the peak phase in a voltage-controlled mode based on a peak voltage;
• during the ramp down phase of the pulse cycles, controlling the power conversion circuitry in the current-controlled mode based on comparing the output current of the power conversion circuitry to the target current while ramping down the target current;
• and
• in response to reaching a background transition voltage, switching to controlling the power conversion circuitry during the background phase in the voltage-controlled mode,
• wherein the control circuitry is configured to determine the peak transition voltage as an offset to the peak voltage, wherein the peak transition voltage is lower than the peak voltage.
