In actual operation, all of the apparatuscan be removed so quickly from the track that a trainservice, comprising twenty-five to thirty limiteds be-sides locals and freights, can be carried on without stopsand with comparatively few slow-downs. The portabil-ity of the apparatus makes it possible to carry on thework in the day time at the most difficult locations in-stead of going to the expense of night labor. These portable welders are extremely simple. Eachis made up of a small larry on which the rheostat andthe supplies are carried and a welding furnace whichcontains an electrode and the graphite plate in connec-tion therewith. On the Cleveland, Southwestern job,the helper is used by the welder mainly for opening and DAILY REPORT BONDING SHEET. Malcfml Needed FORM FOR DAILY REPORT OF BONDING closing the rheostat switch and for removing this out-fit from the track. The welder can open the switchhimself by pulling a string if he so desires. The helperis also used in laying out bonds, preparing graphiteplates and the like. A number of time studies made of welding by thismethod showed that the average time of applying anErico E. T. No. 0000 5%-in. bond, from the time ofclamping the welding furnace to the rail to its removalfrom the rail, varies from two to two and one-half min-utes depending upon such factors as the experience ofthe welder and the newness of the graphite plates. Theolder the plates the quicker the weld. As the bondingplaces are scattered, maximum output is not , the two gangs have installed a total of 175 to200 bonds in a ten-hour day, of which period only eighthours were devoted to actual welding operations. Onthis basis the labor cost per bond averages 10
