Abstract (en)

[origin: CN112530684A] The invention relates to a welding transformer, a method for producing a module for a welding transformer and a method for producing a welding transformer. The welding transformer comprises a magneticcore, at least one primary winding wound around the core such that the at least one primary winding can be connected with a power supply to supply a primary voltage to the at least one primary winding, and at least two modules, wherein each module of the at least two modules is formed as one component which comprises at least one secondary winding wound around the core such that the at least onesecondary winding can transform the primary voltage into a secondary voltage used for supplying a welding current to the welding tool, and a mounting unit for mounting to the welding transformer a rectifier for rectifying the secondary voltage to supply a direct current as the welding current to the welding tool.
