Motors and Controllers The Lincoln Electric Company 13036 Coit Road, Cleveland, Ohio Largest Manufacturers of Arc Welding Equipment in the World Branch Offices and Distributors In AH Principal Cities Manual and Automatic Arc Welding Equipment, Electrodes and Supplies; A.C. Motors in Standard Types 34 to 200 H.P. Shielded Arc Welding Welding Electrodes Welds made by the shielded arc with Lincoln equipment have a tensile strength of 65,000 to 75,000 pounds per square inch, ductility and`density equal to 'mild rolled steel and greater resistance to impact, fatifue and corrosion.-; Shielded'arc welding is used in the fabrication of'pipe systems, steam, water, oil and gas transmission lines, also in the fabrication of ducts and other sheet'metal products, also in the con struction ' of fan and blower housings, boilers, furnaces, tanks and pressure vessels. Shielded arc welding under the proper procedure satisfies all the require-' ments of the A.S.M.E. Boiler Code and insurance regulations. "Fleetweld"--For shielded arc welding of pipe, plate and shapes. Welding speed 150 to 300 per cent faster than ordinary welding. "Lightweld"--For shielded arc weld ing of 16-24 gauge metal. "Stainweld A"--For welding 18-8 stainless steel. "Aluminweld"--For welding alumi num. "Ferroweld"--The electrode that solves cast-iron welding problems. "Hardweld"--A high carbon rod for hard surfacing. "Manganweld"--For welding high maganese steel. ``Stable-Arc''--A non-splashing rod for general welding purposes. The Lincoln "Shield-Arc" Welder Lincoln "Shield-Arc" welders have many exclusive patented features which make possible the following 3-way guarantee of welding with "Shield-Arc" welders: 1. More weld metal deposit per K.W.H. 2. Faster welding.per K.W.H. 3. Lower cost per unit of welding--the unit being per lineal foot of weld, or per pound of weld metal, or per hour of welding. Lincoln welders, A.C. and D.C. motor driven, are built in 100 to 400 ampere sizes; belt and gasoline driven types in 100 to 600 ampere sizes. Lincoln "Line-Weld" Motors Known as the motors which de liver extra horse power without sacrifice of power factor or efficiency. Arc-welded rolled steel" frames pro vide structural. The Motor with the Extra Horse strength without power, Lincoln "Linc-Wdd" bulk. This permits Type D larger openings for greater venti lation, resulting in cooler opera tion of motors. Built in all stand ard types of poly phase induction motors for pump, , ,1 fan and blower Malar "f** Lmc-W.di Type -B, Totally. Bnjdotei, Fan Coded service, also for other general and special purposes. Use of the stainless steel motor, the "Line-Weld," Type E (totally enclosed, fan cooled), is recommended wherever there is dust, dirt, moisture or fumes in suf ficient quantities to clog an open type motor or to abrade and corrode windings and bearings. Though completely sealed, the "Line-Weld" Type E stainless steel motor operates continuously at full load well within the N. E. M. A. allowable tem perature rise of 55 degrees Centigrade. 722 Motors and Controllers Westinghouse Electric & Manufacturing Go. East Pittsburgh Pennsylvania Research, Application and Design Engineers will cooperate and solve any electrical problem for heating and ventilating systems. Sales Offices and-Service Shops in all Principal Cities Quiet Operating Motors The Westinghouse Company has long recognized the need for quiet operating machinery and has devoted a vast amount of research work to the development of special instruments to measure noise ac curately. The human element, which gives variable results, is eliminated in all testing procedure. Westinghouse Quiet Operating Motors are specially designed and individually For fan drives, the new Westinghouse Type O-l Controller offers unusual ad vantages. This unit assembly includes the equipment ordinarily housed in three separate cabinets. Primary Linestarter, A Type CW Variable Speed, Quiet Operating Motor Driving Pan tested under loaded and unloaded con ditions in a sound-proof room. A special nameplate is your assurance of their high standard of quiet operation. Lasting quietness is assured by rigid, unit cast motor frames which contribute to the permanence of bearing alignment and air gap. Rotors are given a special dynamic balance, practically eliminating noises due to vibration. Motor Control speed regulator and Nofuze breaker for circuit disconnect and protection are all mounted and wired in a neat cabinet for wall or floor mounting. Installation .is greatly simplified and its appearance is improved. Arc Welding FlczArc A-c. Welder for Simplified Fabrication Linestarter for A-c. Drives A Close lt-016 Speed Regulating Rheostat for use with Pan Drives Starters, speed regulators, thermostats, switches and Nofuze circuit breakers are available for every requirement. For the fabrication of thin-gauge ma terials such as ducts, Westinghouse'offers the FlexArc A-C. welder. Its operation is extremely simple and it uses less than 15 cents worth of power an hour. One man can wheel it easily from place to place. It operates from the ordinary single-phase power circuit. 723 /
