    Abstract: A stud welder is provided with a pair of magnetic coils and a compression spring. One of the coils provides the lift to separate electrode held parts and start an arc therebetween. The other coil and the compression spring provide fast follow-up force driving the parts into reengagement to quench the arc and weld the parts together. The combined acceleration of the spring and the booster coil enables the welding of certain materials such as brass which were previously not weldable with stud welders.

    Abstract: Stick and stud welding apparatus which utilizes a microprocessor and related RAMs, ROMs and peripheral interface devices to control the welding parameters. The ideal desired weld current and weld cycles in the case of stud welding can be selected depending upon the mode of operation and/or stud conditions. The program for the microprocessor instructs the microprocessor to periodically compare the actual welding current to the ideal current, compute the difference and alter the phase firing time of an SCR bridge to compensate or adjust the welding current to the ideal current. In the case of stud welding mode, the program further instructs the microprocessor to reference the selected number of cycles, compute the total energy delivered across the stud and workpiece gap from actual current, welding terminal voltage and time and enlarge the number of actual weld cycles to a given percentage of that initially selected to provide a total energy input to the stud as selected. In the stud mode, the pilot arc current and cycles may likewise be selected and controlled. Such parameters as pilot arc current, pilot arc cycles, main welding current, main welding current cycles, total energy, welding terminal voltage and error occurrence are displayed visually by means of lights and/or written printout.

    Abstract: In the stud welding apparatus disclosed a battery or bank of capacitors in the main welding line stores welding energy. A current supply unit charges the bank of capacitors. An electronic switch applies the energy from the bank of capacitors to welding electrodes. A control device, which can be turned on and off, renders the electronic switch conductive when it is turned on. A safety circuit reduces the output voltage of the current supply unit when the electronic switch happens to turn on while the control device is turned off. The safety circuit also reduces the voltage across the bank of capacitors.
