    Abstract: A power supply for welding, cutting and similar operations includes a dual two-switch forward converter. The converter has two inverter circuits coupled in parallel but controlled to provide output power in an interleaved fashion. To avoid “walking” of the circuits (which could result in different duty cycles and imbalance of the load sharing), control signals are determined and applied to a first of the inverter circuits, and “on” times of the first circuit is monitored, such as by augmenting a counter to determine the number of clock cycles the first circuit is “on”. The same duration is then used for commanding output from the second inverter circuit. The duty cycles of both circuits is thus ensured to be the same regardless of changes in the total output power.

    Abstract: In certain embodiments, a welding system includes an interface with a first input element configured to receive an input relating to a parameter of power delivered to a welding torch from a welding power supply, a second input element configured to receive an input relating to a rate of advancement of an electrode delivered to the welding torch from a welding wire feeder, a third input element configured to receive an input relating to whether the parameter of power and the rate of advancement of the electrode are automatically set, and a color display device configured to display the parameter of power and the rate of advancement of the electrode. The welding system also includes control circuitry configured to adjust and display on the color display device the parameter of power and the rate of advancement based at least in part on a selected diameter setting for the electrode and a selected material thickness setting for a work piece when the third input element is activated, and to control the parameter of power and the rate of advancement based on the adjustment of the parameter of power and the rate of advancement.

    Abstract: Systems and methods to control pulse welding are disclosed. An example welding-type system includes: 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. Controlling the power conversion circuitry involves: during the ramp up phase of the pulse cycles, controlling the power conversion circuitry in a current-controlled mode and switching to controlling the power conversion circuitry in a voltage-controlled mode when a peak transition voltage is reached; and during the ramp down phase of the pulse cycles, controlling the power conversion circuitry in a current-controlled mode and switching to controlling the power conversion circuitry in a voltage-controlled mode when a background transition voltage is reached.
