SYSTEMS AND METHODS TO CONTROL WELDING-TYPE POWER SUPPLIES USING AC WAVEFORMS AND/OR DC PULSE WAVEFORMS

Abstract:

An example welding-type power supply includes: power conversion circuitry configured to convert input power to welding-type power having at least one of an alternating current (AC) waveform or a pulse waveform; an interface configured to receive an input representative of a selected frequency of the AC waveform or the pulse waveform; and control circuitry configured to: determine an amperage parameter of the welding-type power; based on the amperage parameter, determine a range of frequencies of the AC waveform or the pulse waveform; control the interface to output an indication of the selected frequency with respect to the determined range of frequencies; and control the power conversion circuitry to output the welding-type power at the selected frequency and based on the amperage parameter.
