WELDING TRANSFORMER, METHOD FOR PRODUCING A MODULE FOR A WELDING TRANSFORMER AND METHOD FOR PRODUCING A WELDING TRANSFORMER

摘要

There is provided a welding transformer (30), a method for producing a module (34; 3401; 3402) for a welding transformer (30) and a method for producing a welding transformer (30). The welding transformer (30) comprises a magnetic core (33), at least one primary winding (31) wound around the core (33) such that the at least one primary winding (31) can be connected with a power supply (25) to supply a primary voltage to the at least one primary winding (31), and at least two modules (3401, 3402), wherein each module (3401, 3402) of the at least two modules (3401, 3402) is formed as one component which comprises at least one secondary winding (32; 341) wound around the core (33) such that the at least one secondary winding (32; 341) can transform the primary voltage into a secondary voltage (U21, U22) used for supplying a welding current (I2) to the welding tool (10), and a mounting unit (342) for mounting to the welding transformer (30) a rectifier (40) for rectifying the secondary voltage (U21, U22) to supply a direct current as the welding current (I2) to the welding tool (10).
