[0002] A welding wire is a welding material in the form of a filler metal or also as a conductive metal wire. In gas welding and tungsten inert gas arc welding, the welding wire is used as a filler metal; in submerged arc welding, electroslag welding and other gas metal arc welding processes with a consumable electrode, the welding wire is both a filler metal and at the same time a conductive electrode. The surface of the welding wire is not coated with a flux for anti-oxidation. During the production process of the welding wire, the welding wire will be cleaned to remove impurities and cool down, and after the cleaning is completed, the welding wire needs to be dried.

The plurality of heating tubes are respectively installed inside the two mounting frames. An air suction fan with an air inlet end extending into the drying box is installed on the upper end surface of the drying box.

By starting the suction fan 17, the moisture inside the drying box 1 can be sucked out, so as to achieve the purpose of facilitating the pretreatment of the moisture on the surface of the welding wire, improving the drying effect, and avoiding incomplete drying.

[0038] Insert the two limit blocks 6 into the two limit grooves 9 respectively. Since they are a matching square structure, the two mounting blocks 7 can be prevented from deflecting. Then screw the two tightening blocks 11 onto the outer walls of the two screws 10 and press them against the two mounting plates 5 respectively, so as to fix the two water-absorbing sponges 8. When it is necessary to remove them, by unscrewing the two tightening blocks 11, the two mounting blocks 7 together with the two water-absorbing sponges 8 can be removed, so as to achieve the purpose of facilitating the replacement of the water-absorbing sponge 8.
