Abstract
In order to reduce the accumulation of moisture on a welding wire (″) arranged in a welding wire cartridge () or to remove existing moisture in a simple and reliable manner, it is provided that a flow (D) of purging air supplied to the welding wire cartridge () is adjusted by a flow control unit (), the purging air is supplied to the flow control unit () at a first pressure (p) and is discharged at a purging air discharge () of the welding wire cartridge () at a third pressure (p), and at a purging air feed () of the welding wire cartridge () a second pressure (p) at the purging air feed () that is lower than the first pressure (p) results from the adjusted flow (D), the third flow (p) and a flow resistance between the purging air feed () and the purging air discharge (), the relative humidity (rF) of the purging air being reduced by the relief of pressure from the first pressure (p) to the second pressure (p).
