摘要： The present application relates to a welding-type power supply (102) for synergically controling a welding-type output during a welding-type operation. An example welding-type power supply (102) includes a power conversion circuit (110) configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch (106); a communication circuit (118) configured to receive a control signal from a remote control device during a welding-type operation; and a control circuit (112) configured to synergically control at least two of a voltage of the welding-type power output by the power conversion circuitry (110), a current of the welding-type power, or a wire feed speed.

摘要： Disclosed example power supplies, user interfaces, and methods are provided for simple and intuitive setup for configurable and/or default settings for a welding power source and/or wire feeder. The welding parameters may correspond to a default and/or factory setting that represents empirically adduced values for a particular welding procedure (e.g., based on material type, electrode diameter, welding process and/or tool, etc.). The welding parameters may additionally or alternatively be configured for a particular purpose. Once a configurable setting has been selected, the configurable setting controls the system output. Furthermore, once a configurable set of welding parameters has been established, the operator may return to the default settings by resetting the welding parameters.

摘要： An example welding-type power supply includes: power conversion circuitry configured to convert input power to welding-type power; a user interface configured to receive two or more inputs associated with corresponding qualitative characteristics of a welding arc created by the welding-type power, wherein the two or more inputs are defined within corresponding ranges of the respective qualitative characteristics; and control circuitry configured to: in response to a change in a first one of the two or more inputs, determine a corresponding change in a second one of the two or more inputs based on a relationship between the first and second ones of the two or more inputs; determine two or more welding-type parameters based on the two or more inputs; and control the power conversion circuitry based on the determined welding-type parameters.

摘要： 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.
