    Abstract: A welding system and method having power controller with workpiece sensor. In some embodiments, the welding system includes a stud welding power supply having a welding power output, a stud welding power controller, and a workpiece sensor. The stud welding power controller may be communicatively coupled to the stud welding power supply and the workpiece sensor. In certain embodiments, the stud welding power controller is responsive to a signal from the workpiece sensor indicative of a position of a stud in general proximity or engagement with a workpiece.

    Abstract: An appartus and method for a stud welder power source is disclosed. The power source has a control circuit connected to an inverter which converts an electrical signal from a power source into an electrical signal that can perform stud welding. The inverter conditions the power signal such that a current of at least 1000 amps can be generated nearly instantaneously. Additionally, having a power source that includes a control circuit with an inverter allows for a smaller and lighter appartus when compared to known stud welders.
