TRANSFORMER FOR THE ARC CUTTING AND WELDING Russian patent published in 1995 - IPC

FIELD: welding engineering. SUBSTANCE: transformer for the arc cutting and welding has a magnetic circuit on whose rod the sectional primary and secondary windings with alternating sections and an additional winding are disposed. The alternating sections of the windings are made in the form of axial and radial rows concentric on the symmetry axis of the magnetic circuit rod. In each odd axial row the extreme sections of the primary winding are equipped with those of the additional winding wound on them. In each oven axial row the extreme sections of the secondary winding are wound on those of the additional winding. The middle section of the primaey winding of the even axial row is wound on that of each odd axial row of the secondary winding. The missle section of the additional winding is wound on that of the primary winding of the even axial row. EFFECT: facilitated manufacture. 6 dwg
