#CMT# #/CMT# The gas-shielded welding device (1) comprises a gas supply (2), a control unit (3), a handheld device, gas feed lines (6, 7), which connect the gas supply, the control unit and the handheld device, and a gas-drying device (12) arranged in an area of the gas feed line between the gas supply and the control unit and/or the gas feed line between the control unit and handheld device. The gas-drying device is detachably connected with the gas feed line, the control unit and/or the handheld device, is arranged in a part of the gas feed line connected to the handheld device and comprises a heater. #CMT# : #/CMT# The gas-shielded welding device (1) comprises a gas supply (2), a control unit (3), a handheld device, gas feed lines (6, 7), which connect the gas supply, the control unit and the handheld device, and a gas-drying device (12) arranged in an area of the gas feed line between the gas supply and the control unit and/or the gas feed line between the control unit and the handheld device. The gas-drying device is detachably connected with the gas feed line, the control unit and/or the handheld device, is arranged in a part of the gas feed line connected to the handheld device and comprises a heater, a replaceable drying cartridge with a drying agent such as silicagel and/or molecular sieve and a cooling case e.g. a heat exchanger flowed through by a cooling agent. #CMT#USE : #/CMT# Device for gas-shielded welding. #CMT#ADVANTAGE : #/CMT# The gas-shielded welding device prevents the entry of moisture in the welding area of the welding wire, and reduces the occurrence of hydrogen-porosity or prevents the presence of gaseous hydrogen in the area of the welding point. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic representation of a welding device. 1 : Device 2 : Gas supply 3 : Control unit 6, 7 : Gas feed lines 12 : Gas-drying device.
