摘要
The invention relates to a welding tool coupling, in particular a hose-assembly interface 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 that can be switched on and off. According to the invention the coupling device (2) has at least one magnet system (10) and at least one short-circuit device, 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 the magnet system (10) exits from the coupling device (2) in the switch-on position in such a way that the magnetic retaining force is generated and is at least partially short-circuited in the coupling device (2) by means of the short-circuit device in the switch-off position in such a way that the magnetic retaining force disappears. The invention further relates to a welding tool (3) for coupling to such a welding tool coupling, and a welding device having such a welding tool coupling.
