摘要： A drawn arc welding device includes a welding tool, and an energy storage device coupled to a power source. A charging circuit is connected to the energy storage device replenishing the storage device. A discharge circuit is connected to the welding tool and energy storage device. The discharge circuit regulates and adjusts a welding current of the welding tool to a specified amount. Also disclosed is a process that includes charging the energy storage device, actuating the welding tool, energizing a pilot arc current, lifting the weld stud off a workpiece to draw the pilot arc, energizing a welding arc wherein the discharge circuit regulates a welding current of the welding tool to a specified amount, and plunging the weld stud into the workpiece and turning off the discharge circuit.
