    • The invention relates to electrotechnical engineering, in particular to devices for electric arc welding and to a method for producing the magnetic core of said devices. In order to reduce the mass of the device and improve the technical and economic characteristics thereof, in one variant, the inventive device for electric arc welding comprises an electric transformer and a choke whose primary windings are series connected for connecting to a variable voltage network and forming a common winding which is arranged on the first part of the magnetic core thereof. A secondary winding of the transformer is arranged on the second part of the magnetic core and embodied in such a way that the XX cross-section thereof saturates the magnetic core. Said secondary winding is used for connecting to electrode and earthing terminals. An additional winding of the choke coil is arranged on the third part of the magnetic core in such a way that it is possible to carry out a connection in daisy chain in order to regulate the arc current according to the common winding.

    • The invention relates to a transformer including a first (1), a second (2) and a third (3) leg which are aligned in parallel and are magnetically connected, having at least a first primary winding (4) and at least two secondary windings (5, 6). Each of the windings are carried by a different leg, whereby the legs are arranged in a sequence and one of the secondary windings is located between the other two legs. The two legs are connected with a capacity (7) and thus form a resonance circuit. The magnetic connection between the two secondary windings differs from the magnetic connections between the primary and each of the secondary connections. The flux excited by the first secondary winding is anti-parallel to the flux excited by produced by the second secondary winding. A supply voltage can be supplied at the primary winding and the transformer provides a current and a voltage at the secondary windings.

    • The invention relates to a mid-frequency high power transformer (10) which is specially used as a welding transformer in resistance welding, comprising a primary winding penetrated by the limb of a transformer core (24) and a secondary winding which are configured as concentrically overlapping cylindrical windings. The windings of the primary winding(s) (36; 38) are formed by a plurality of spirally wound layers of a relatively thin electrically conductive metal strip material, and the windings of the secondary winding (4) are formed by an appropriate number of spirally wound layers of a thicker electrically conductive metal strip material chosen according to the desired reduction ratio between the primary and the secondary windings. The width of the winding layers of the metal strip materials measured perpendicularly in relation to the longitudinal direction is substantially identical to or only slightly smaller than the length of the limb (26) of the transformer core (24) penetrating the windings, and the connection lines (44, 46) on the secondary winding are connected to the front face edges of the windings of the strip material of the secondary coil (40).
