Title: Improvements relating to electric switching apparatus
IPC: B23K11/24
Filed: 1949-08-22
Abstract: 691,680. Switching systems. HIRST ELECTRONIC DEVELOPMENT, Ltd., and COLLINS, F. Aug. 14, 1950 [Aug. 22, 1949], No. 21707/49. Class 38 (iv). A control system for a spot-welding contactor C which provides for precise adjustment of the points in the A.C. supply voltage wave at which the contactor opens or closes, comprises cold-cathode discharge tubes A, B, relays G, H, timing circuits L, K, synchronizing circuits N-N4 and a transformer F by which the control apparatus is powered. Assuming a switch D set to the seam, or " continuous spot," welding position D1, closure of a starting switch E applies D.C. to the anodes of the two tubes from condenser F5 which is maintained on charge over rectifier F4 from transformer winding F1. Condenser K associated with the grid of tube A commences to charge over its adjustable timing resistor L (and contact H1 of relay H) and the tube eventually fires, under the control of a triggering pulse supplied by the relevant synchronizing circuit. This circuit is energized by transformer winding F2, which is shunted by condenser N1 and variable resistor N forming an adjustable phase-shift network by which the firing-point of tube A in relation to the voltage supply wave to transformer F may be accurately adjusted. Relay G picks up when tube A fires, its contacts G3 completing an energizing circuit for the coil of the welding contactor, thereby initiating flow of current in the welding circuit. Change-over contacts G1, G2 also operate and connect the other condenser K (which had previously been discharged by a resistor M) for charging over its associated timing resistor L. The grid voltage of tube B progressively rises and eventually the tube is fired by a triggering pulse from its associated synchronizing circuit, which also includes an adjustable phase-shift circuit for controlling the firing-point. Relay H responds upon conduction of tube B and de-energizes tube A and relay G by opening contacts H3. The contactor C consequently opens to terminate flow of welding current. Contacts G1, G2, H1, H2 change over to discharge condensers K and after a delay imposed by a circuit Q, Q1, relay H drops out (due to open contacts H3) and restores initial conditions. The cycle repeats until switch E is opened. The synchronizing circuits are preferably so adjusted that the contactor opens and closes at zero current points in the welding circuit. To effect a single spot weld, switch D is moved to position D2, thereby preventing de-energization of tube B when contacts H3 open; consequently a second weld can only be effected by first opening and then closing switch E.
