Abstract

331,998. McLoughlin, H. F. May 27, 1929. Welding.-In an elec tric welding machine the electrodes are so arranged and connected to an A.C supply that current flows simultaneously trans versely to and paralle with length of pressure closed seam. Two pairs of electrodes c, c', d, d' are employed and are connected to a three-phase supply pipe e<1>, e<2>, e<3>. Pressure rollers f<1> - - f<6> are arranged as shown. The pairs of electrodes are adjustable vertically by means of screws j and are connected to the secondaries of the transformer h through mercury cups i and conductors A. B, C. The distance between the pairs may be varied by means of a screw k. The pressure exerted by the rollers f<1> - - f<6> may be varied by screws m.
