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.

Welding system and method having power controller with workpiece sensor

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.

Stud welder

A welding stud apparatus and method of manufacturing a welding stud are disclosed. The welding stud has a weld end constructed to be welded to a workpiece that has at least one recess formed therein. The recess decreases an effective arc area of the weld end to localize a current therethrough and increase the efficiency with which the welding stud can be welded to a workpiece.

Welding stud

A welding apparatus is presented that includes a post-firing detection system and control connected to communicate with the post-firing detection system such that a stud welding gun is prevented from activation if a recently fired welding stud remains connected to the stud welding gun.
