FIELD: electric engineering.
SUBSTANCE: invention relates to electric engineering. The transformer is comprised of two double-window magnetic cores (1), primary (2) and secondary (3) windings, and hollow rod (4) with wounded choke (5) winding. The said hollow rod is filled with magnetic liquid (6) and connected to tank (11) with magnetic liquid (6) by means of pipeline (7) through reverse switch (9), operated hydraulic pump (8). The above-mentioned switch is installed in electrode (10) holder handle. There is hole (12) in rod wall (4) whereby inner cavity of rod (4) communicates with atmosphere.
EFFECT: smooth remote control of welding current and improved reliability of operation.
