First Claim
Patent Images
1. A method for controlling a welding process, comprising:
- receiving a signal indicating an operator intention to terminate a welding arc;
stopping advance of a welding wire in response to the signal; and
reducing a conduction angle for switching of solid state switches that generate welding power in response to the signal.

11. A welding system, comprising:
-
a welding power supply configured to generate welding power for an arc welding application, the welding power supply comprising solid state switches that generate welding power, and a capacitive circuit coupled to the welding power; a welding torch for initiating feed of a welding wire for the arc welding application; and control circuitry configured to receive a signal from the torch indicating an operator intention to terminate a welding arc, to stop advance of a welding wire in response to the signal, and to reduce a conduction angle for switching of solid state switches that generate welding power in response to the signal to dissipate energy stored in the capacitive circuit through the welding arc. - View Dependent Claims (12, 13, 14, 15)
