Abstract
The invention relates to a method for cleaning a contact tube () of a welding torch (), via which contact tube a welding wire () is supplied with electrical energy, said welding wire being moved towards the welding torch () by a wire reel () or a welding drum via a wire feeder (), as well as to a welding plant () and a contact tube () for the welding torch () of such a welding plant (). In order to prolong the service life of a contact tube () of a welding torch (), the invention provides that the welding wire () is at least once moved backwards in the direction of the wire reel () or wire drum until the end () of the welding wire () lies at least within the length () of the contact tube (), and that the welding wire () will subsequently again be moved forwards, in particular moved backwards into its starting position.
