This watt-hour meter can also be readily transferred to the otherboards if desired. The total energy supplied for all weld-ing work is recorded by means of an integrating wattmeterin. the feeder circuit, and a regular charge is made at therate of 1 cent per kw-hr. to each job for the energy used. Current for each set is taken through two circuit-break-ers, one on each leg of the line, the negative side passingdirectly through a flexible cable to the burner or torch,while the positive is applied to the work after being ledthrough the proper combination of resistances. All work isplaced on an insulated table, and the men stand on fiber. Third Avenue Welding—No. 57 Motor with Original Frame mats. The operators torch consists of a pipe 5/2 in. in diam-eter and about 2 ft. long. The outer end of this torchcarries a carbon pencil while the inner end is attached tothe negative lead. The back of the pipe is well insulated Table I.—Record of Welding Done During Week Ended Jan. 25, 1913 Unit Total Cost Cost Work Done New NewWelding axle lugs on seven Westinghouse-56 motors (half shell without fittings) $ $ Welding one K-8 broken controller frame Welding five pony axles around button Welding Westinghouse-3 ] 0 armature shafts, one broken and two with worn keyway and pinion fit (shaft) Total $ Cost of labor $ Cost of material Cost of current at 1 cent per kw-hr Total Saving $ to permit its use as a handle, and a round fiber shield isalso applied at the middle of the pipe to protect the handof the operator from the arc.
