Abstract
142,521. Holslag, C. J. Jan. 14, 1918, [Convention date]. Transformers.-A transformer for use in alternating-current welding-apparatus has a primary 3 wound on the leg 2 of the core, a main secondary 7 with its turns mingled with those of the primary, and an auxiliary secondary 5 on the core leg 6. The two secondary windings are in series, and tappings are provided on primary and secondaries. A flux-diverter 15 of laminated bars may be moved across the yokes 21 and its position regulated by the screw 19 and handle 20. Specification 120,886 is referred to.
