Zusammenfassung:	A welding component, such as a remote pendant or wire feeder includes an inrush current control circuit. The welding component may be coupled to a welding power source when the power sources is live and outputting power. Power is stored in the component, such as in capacitors, for operation of a local power supply, such as for an operator interface, display, and the like. Upon connection to the power source, the current application to the capacitors may be delayed to reduce or prevent arcing. The inrush current may also be limited, as may the voltage, to similarly reduce arcing and to provide additional benefits.
