Abstract:
A weld circuit for use in a welder is provided. The weld circuit comprises a charge section, a capacitor section, and a weld section. The charge section includes a first plurality of solid state switches, e. g. , silicon controlled rectifiers (charge SCRs), the capacitor section includes a weld capacitor, and the weld section includes a second plurality of solid state switches, e. g. , silicon controlled rectifiers (weld SCRs). The charge SCRs form a bridge between the lines in the charge circuit. One weld SCR is coupled to a first weld terminal and the other weld SCR is coupled to a second weld terminal. The charge and weld SCRs isolate the charge section, the capacitor section, and the weld section from each other. The weld circuit is coupleable to a safety circuit that comprises a resistor, a microcontroller, and optical isolators. When the optical isolators are enabled, the microcontroller monitors a current flowing through the resistor.

Abstract:
A heat adjustment mechanism for a stud welding tool comprises an adjustment knob comprising adjustment ribs, a solenoid sleeve that moveably engages the adjustment knob, and that receives a solenoid, wherein the solenoid is configured to engage a fastener, and the solenoid is connected to the solenoid sleeve by the fastener, a clutch comprising adjustment ribs that engage the adjustment ribs on the adjustment knob, and a clutch spring that exerts force on the clutch. A weld heat setting adjustment may be made by solenoid movement of from about 0. 15 mm to about 0. 30 mm.

Abstract:
The present technology relates to adjustment mechanisms for control settings on stud weld tools. Stud welding tools typically have a body that comprises a handle, a front end and a rear end. In one aspect, the present technology relates to plunge adjustment mechanisms for stud welding tools that are located at the front end of a stud welding tool and provide an adjustment knob for manual plunge adjustment. Another aspect of the present technology relates to weld heat adjustment mechanisms for stud welding tools that are located at the rear end of a stud welding tool and provide an adjustment knob for manual weld heat adjustment.
