Abstract: A welding system includes an interface having 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 and to alternatively receive an input relating to a thickness of a work piece, 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 and to alternatively receive an input relating to a diameter of the electrode, and a third input element configured to receive an input relating to a welding process type. The welding system also includes control circuitry configured to automatically adjust the parameter of the power and the rate of advancement of the electrode based on the input relating to the welding process type selected with the third input element when the second input element receives the input relating to the diameter of the electrode.

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: A power conversion assembly for use in a welding power supply includes a power magnetics module and a power electronics module. The power magnetics module includes at least one transformer disposed on a first wind tunnel housing. The power electronics module is separate from and electrically coupled to the power magnetics module. The power electronics module includes switching circuitry and one or more heat sinks to remove heat from the switching circuitry. The switching circuitry and the heat sinks are disposed on a second wind tunnel housing coupled to the first wind tunnel housing.
