ELECTRIC-ARC WELDING EQUIPMENT OF TANK REPAIR SHOP Russian patent published in 2000 - IPC

FIELD: military engineering. SUBSTANCE: equipment may be used for perfection and development of perspective shops for maintenance and repair of armored equipment. To maintain stable welding current selected in compliance with welding condition, at moment electrode is closed onto metal to be welded, welding current is corrected by rotation of handle of remote-control rheostat. In case of metal cutting as well as faulty frequency regulator of electric power plant, shop driver must be in cabin to execute welder's commands for changing rotational speed of electric power plant. Welding current is adjusted by means of potentiometer which changes conductance (resistance) of thyristor in circuit of generator excitation winding. Potentiometer is mounted in electrode holder handle. EFFECT: enlarged functional capabilities. 1 dwg
