The third contact device is movable relative to the first and second contact devices. The first contact device has an elongated form, is fixedly arranged in the housing, and extends from a first end, which is arranged between first and second ends of the housing, to a second end. The second contact device has an elongated form, is suspended spring-loaded to the housing, and extends from a first end, which is arranged between the first and second ends of the housing, to a second end.
Claims25
Contact fitting for feeding current to at least a first welding wire and a second welding wire and arranged for a welding apparatus, which contact fitting comprises a length axis, a housing, with a first end and a second end, which is arranged to allow the welding wires to run parallelly with the length axis from the first end of the housing to the second end of the housing, a first contact device which is arranged to be in contact with only the first welding wire, a second contact device which is arranged to be in contact with only the second welding wire and a third contact device which is arranged between the first contact device and the second contact device, which is movable in relation to both the first contact device and the second contact device and arranged to be in con tact with both the first welding wire and the second welding wire, characterized in that
- the first contact device has an elongated form, is arranged fixed to the housing and extends from a first end, which is arranged between the first end of the housing and the second end of the housing, essentially parallelly with the length axis to a second end, and
- the second contact device has an elongated form, is suspended spring-loaded in the housing and extends from a first end, which is arranged between the first end of the housing and the second end of the housing, essentially parallelly to the first contact device to a second end.
