1. A welding-type power supply, comprising:
power conversion circuitry configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch;
communications circuitry configured to receive a control signal from a remote-control device during a welding-type operation; and
control circuitry configured to:
in response to initiation of a welding process via the remote-control device, control the welding-type power and a wire feed speed based on a predetermined weld start sequence;
determine a value of the control signal at the conclusion of the predetermined weld start sequence; and
after the predetermined weld start sequence, synergically control, based on comparing the control signal to the value of the control signal at the conclusion of the predetermined weld start sequence, at least two of a voltage of the welding-type power output by the power conversion circuitry, a current of the welding-type power, or a wire feed speed.
