Abstract: 444,297. Control systems for welding arcs. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 15, 1935, No. 28471. Convention date, Oct. 16, 1934. [Class 38 (iv)] [See also Group XXXVIII] In a system for controlling the voltage across a load circuit, more particularly the circuit of a welding arc from the position at which the load is located, the supply voltage may be raised or lowered through the intermediary of a polarized relay which is operated in one direction or the other by an auxiliary A.C. supply applied through a rectifier arranged in the load circuit. As shown, the supply voltage is generated by a generator 10, preferably of the type described in Specification 159,374, [Class 35], and having series and shunt fields 23, 21, the former of which is tapped by a switch 25 and the latter is connected through a regulator 22. The regulating equipment is operated by a motor 27, the switch being driven through Geneva mechanism 28. The motor is controlled for rotation in one or other direction by a polarized relay 29 which is operated from an auxiliary source of supply 34 over a circuit including the welding electrode 15, the work 16 and a portable rectifier 33 which may be placed between the electrode and the work so as to pass either positive or negative half-waves of the alternating current. When satisfactory regulation of the supply voltage is accomplished, the rectifier is removed and the electrode 15 is placed in contact with the work to produce sufficient current to operate relay 41 which pulls up locking relay 36 to connect the supply voltage to the load and disconnect the auxiliary A.C. source. The generator is provided with brushes 19, 20, 18, the brushes 19, 20 producing substantially constant voltage while the voltage between the brushes 20, 18 varies according to the condition of the arc. In a modification, instead of providing a third brush, a tapped potentiometer connected across a pair of brushes may be employed.
