| abstract | 907,473. Control systems for stud welding. WESTINGHOUSE ELECTRIC CORPORATION. May 20, 1960 [May 29, 1959], No. 17813/60. Drawings to Specification. Class 38 (4). An arc welding system, for example a stud welding system, employing semiconducting rectifiers such as silicon diodes is provided with two timing mechanisms, one of which operates to remove the supply after current having a normal welding value has been supplied for a normal welding time, the other of which operates to remove the supply if a short-circuit current tends to flow for a longer time than the system can sustain such a short-circuit current, the time during which the short-circuit current is allowed to flow being substantially shorter than the normal welding time. A third timing mechanism is also provided whereby the supply is removed should the normal welding current tend to flow for a time longer than the normal welding time. The normal welding time may be adjusted from a few cycles up to 1 second, whilst the time an overload current is permitted to flow is limited to 6 cycles or less, that is 0.05 seconds or less. |
