WELDING TOOL COUPLING HAVING AT LEAST ONE MAGNETIC SYSTEM AND AT LEAST ONE SHORT-CIRCUIT DEVICE, WELDING TOOL AND WELDING DEVICE Russian patent published in 2018 - IPC F23D14/40 

FIELD: technological processes.

SUBSTANCE: invention relates to welding tools, in particular to the connection of the coupling, and to the welding device with such a coupling. Invention describes a coupling device for a hose bag or a welding torch handle for connecting a welding tool (3), in particular a welding torch neck, to a supply line of a welding device, comprising a coupling device (2) for detachably coupling the welding tool (3) by means of a magnetic retaining force. It is contemplated that the connection device (2) comprises at least one magnetic system (10) and at least one short-circuiting device (100) which can be moved in relation to each other between a switch-on position and a switch-off position in such a way that the magnetic flux generated by magnet system (10) exits from coupling device (2) in the switch-on position in such a way that the magnetic retaining force is generated and in the off-position by means of short-circuit device (100) at least partially short-circuited in connection device (2), stopping the magnetic retaining force.

EFFECT: invention is intended to simplify the connection of the coupling to the welding tool.
