Electric& Manufacturing Company, Garwood. X. J. The equipment is ex-tremely flexible for welding and repair work in ship yards, ma-chine shops, locomotive shops and foundries. The motor cir-cuit may be connected to any available part of the shop or yardcircuit. The equipment, consisting of dynamotor. control apparatus andswitchboard, is supported on a base of I-beams and mounted ona heavy iron truck. The welding current is generated by a 110-volt dynamotor, the generator end having a capacity of 200amperes at 70 volts. The motor shaft is extended to receive apulley for belt drive, when in usi on barges, in shop yards orwhere electric current is not available. As illustrated, the start-ing box and field control rheostat are mounted on the framestructure supporting the The switchboard carries. Complete Portable Equipment for Electric Welding the main line switch and circuit breaker for the motor, andautomatic control relays for two individual welding circuits. Aset of 400 amperes will provide for one graphite electrode or twometallic electrodes for welding. The graphite electrode gives atemperature of about deg. C, and is used forcutting, pre-dicating and welding with an auxiliary bar. The metaUic weld-ing electrode furnishes the welding metal directly and can be 542 RAILWAY AGE GAZETTE, MECHANICAL EDITION Vol. 88, No. 10 used on vertical or overhead work. The automatic relays ineach welding circuit insert and cut out small steadying resistancesor drawing the arc, and thereby prevent burning of the devices also prevent interference between ammeter in the welding circuit permits the accurate adjust-ment of tlie current to the work.
