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.
