CPC B23K 9/092 (2013.01) [B23K 9/0953 (2013.01); B23K 9/10 (2013.01); B23K 9/1062 (2013.01)] | 21 Claims |
1. 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 portion, a ramp up portion, a peak portion, and a ramp down portion, wherein the controlling the power conversion circuitry comprises:
controlling the power conversion circuitry in a current-controlled mode in the ramp up portion and the ramp down portion;
monitoring one or more output power parameters of the welding-type power during the plurality of pulse cycles;
determining a short state has been entered based on the one or more output power parameters;
when the pulse cycle is in the ramp up portion or the ramp down portion, changing from the current-controlled mode to a voltage-controlled mode in response to entering the short state; and
controlling the power conversion circuitry in the voltage-controlled mode during the short state using a short state target voltage as a command voltage in response to the short state having been entered.
