At the same time, the dust cover 17 will automatically play a dustproof effect to reduce the impurities after welding from entering the rotating groove 12 For the purpose of welding, first insert the welding rod into the welding gun 22, and then start the power supply of the welding gun 22. Then, when it is necessary to change the welding height, first start the power supply of the second motor 21. At this time, the second motor 21 will drive the welding gun 22 to start rotating, so as to achieve the purpose of changing the welding height. When the welding gun 22 reaches the desired position, the power supply of the second motor 21 can be stopped. If it is necessary to change the welding position again, just repeat the above steps. When it is necessary to dissipate the heat of the material to be welded, first connect the pre-prepared water source to the water inlet 36. At this time, the water flow will flow into the first water storage tank 32 and the second water storage tank 34 through the water inlet 36, and then the water flow will flow into the water spray component through the water outlet 35, and then the purpose of cooling the material can be achieved.

When the water flows into the corrugated hose 4 through the water outlet 35, the corrugated hose 4 will play a guiding role by itself. When the cooling position needs to be adjusted, the nozzle 41 is first pulled to put it into the second fixing block 44, and then the cooling position is changed by adjusting the second fixing block 44. At this time, the second fixing block 44 will drive the second rotating shaft 43 to start rotating. When the second fixing block 44 is adjusted to the required position, the pin 46 is inserted into the required slot 45 to fix the second fixing block 44, so as to achieve the purpose of changing the cooling position. At the same time, because the third fixing frame 42 and the dust cover 17 are fixedly connected, when the first gear 13 When the dust cover 17 and the first fixed block 11 are driven to rotate, the third fixed frame 42 will also rotate at the same time. When it is necessary to further cool the material, the power supply of the third motor 52 can be started first. At this time, the third motor 52 will drive the fan blades 54 to start rotating through the third rotating shaft 53, and then the fan blades 54 will drive the air to blow downward to achieve a better heat dissipation effect. When the nozzle 41 is cooling down, the first drain outlet 6 will automatically discharge the waste water, and the waste water tank 7 will automatically collect the waste water falling from the first drain outlet 6.
