Abstract
728,370. Automatic arc control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 16, 1953 [Sept. 17, 1952], No. 23307/52. Class 38 (4). [Also in Group XXII] In a stud welding apparatus a solenoid is connected in series with the arc and when energized from a constant voltage source moves the stud from the work against a counter force to strike an arc, the length of which is self-adjusting until the counter force and the solenoid force are in equilibrium. A stud chuck 1 is mounted on an armature 2 slidable against a spring 7 into the core of a solenoid 6 in the gun body. An insulating shield 8 is fitted to protect the solenoid from welding heat. A tripod 15 is adjustably mounted on the body to allow correct positioning of the stud. The welding current supply lead is connected to the metal bobbin of the solenoid which in turn is connected by a flexible connector 19 to the armature 2. One lead of a three-core control cable is connected to one end of the solenoid coil, the other end of which is connected to the bobbin. The two other leads are connected to a press switch 18. In the control circuit, Fig. 6, with all relays de-energized, the timing condenser C1 is charged from the D.C. constant supply source. On pressing bush-button PB, one coil of relay A is energized from the D.C. source through contacts B1 to close its contacts A1, A2. Closing of contacts A2 energizes relays B, D, relay B changing its contacts to B2 and B4 and relay D closing contacts D1 to energize coil S which closes the welding current supply circuit switch S 1 and the switch K to allow energization of solenoid T. The stud is thus lifted from the work and an arc is drawn. Meanwhile, closing of contacts B2, B4 disconnects relay A from one side of the D.C. source, but condenser C1 then discharges through the coils of relay A for a time dependent on the setting of resistor R1 through which the condenser also discharges. When C1 is discharged, relay A de-energizes, contacts Al, A2 open, thus releasing relay D which de-energizes coil S to break the welding current and de-energizes coil T to allow the spring to pash the stud towards the work. Upon release of button PB relay B de-energizes and the apparatus returns to the original position.
