The heating wire 23 is started, and the heating wire 23 blows the gas entering the heating tube 24 into the The heated gas dries the welding wire 11 passing through the heating tube 24, which is beneficial to prevent the moisture attached to the welding wire 11 from decomposing under the action of the high-temperature arc to produce hydrogen that dissolves in the molten pool and precipitates during the cooling process to form hydrogen pores, resulting in reduced mechanical properties and fatigue resistance of the parts, affecting the production quality of the device. The valve 16 is opened and the pipeline is connected to discharge the air flow containing moisture out of the device.
