Third Avenue Welding—Resistances and Control Apparatusin Basement an axle cap. The man who welded the motor shells alsorepaired the controller frame and eleven axle caps and thiswork required ten out of the sixty hours which constitutea weeks work in the shops. His wages for the week were 1104 $18. Of the charge of $10 for electrical energy, $8 was dueto repairs on the motors. Consequently the cost of repair-ing seven motor shells was $15 for labor and $8 for current,or about $ per shell. This compares with $18 and$ charged by outside contractors for similar For the week ended Feb. 3, 1913, the record of the threeoperators was as shown in Table II on the next page. The data presented are sufficient to demonstrate the low;cost of electric welding, but it should be added that thewelded equipment has proved good in service as well. r
