摘要： Apparatus, devices, and methods for providing a voltage reduction capability in a welding power source for safety purposes. The resistive load and the output voltage of the welding power source output are monitored and compared to predefined or preselected threshold values to generate a load condition signal and an output voltage condition signal (e.g., logic signals). The load condition signal and the output voltage condition signal serve as inputs to a voltage reduction device control logic which generates control signals to enable and disable the input and output of the welding power source according to the defined control logic. As a result, an extra measure of safety in preventing electrical shock is provided to users of the welding power source during hazardous operating conditions.

摘要： A wire feeder including a motor driving a set of feed rolls to force a welding wire from a spool through a welding torch to a welding operation. The wire feeder has an input lead to be connected to the output terminal of a remotely located power source having an on condition and an off condition where a welding current is directed to the output terminal only when the source is in the on condition. A weld starting trigger with a weld start position located adjacent the torch closes a switch when the trigger is shifted to the weld position, a circuit senses when the switch is closed, and a transmitter on the wire feeder transmits a start signal to the power source when the trigger switch is closed whereby the power source is shifted to its on condition when the trigger is in the weld position.
