    摘要: A system and method for welding arc termination are provided. In an exemplary embodiment, a method for controlling a welding process includes receiving a signal indicating an operator intention to terminate a welding arc and stopping advance of a welding wire in response to the signal. The method also includes reducing a conduction angle for switching of solid state switches that generate welding power in response to the signal.

    摘要: Methods and devices for controlling a welding power source based on a primary supply voltage level are provided. One method may include sensing activation of the welding power source and sensing a primary supply voltage established on a control transformer of the welding power source. The method may also include establishing a substantial current draw from a primary power supply that exceeds a predefined current threshold when the sensed primary supply voltage exceeds a predefined voltage threshold. The substantial current draw may be adapted to trip a circuit breaker of the welding power source to disallow current through the welding power source when the sensed primary supply voltage exceeds the predefined voltage threshold.
