[0028] Reference Figure 4-5 A second filter screen 21 is provided in a side wall of the collecting box 5 close to the fan 6 to prevent impurities from entering the fan 6 and reducing the service life of the fan 6.

[0029] The implementation principle of a welding device with a protective function in the embodiment of the present application is as follows: when in use, the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 drives the welding gun 12 to move downward to weld the workpiece, and at the same time the electric push rod 13 is started, and the electric push rod 13 drives the gas collecting hood 11 to adjust the height along the welding gun 12, so that the welding gun 12 is covered in the gas collecting hood 11, and the fan 6 is started, and the powder slag and toxic gas generated during welding are sucked into the collection box 5 through the suction hood, and the powder slag falls into the first filter screen 16 in the first installation frame 7 for filtration, and the toxic gas passes through the first filter screen 16 and the third filter screen, and is filtered through the activated carbon filter layer 15, and then the harmless gas after filtration is discharged through the outlet pipe 14. When the first filter screen 16 and the activated carbon need to be replaced, the second pull rope 10 is pulled, The second pull rope 10 drives the first pull rope 22 to move, and the first pull rope 22 drives the two blocks 17 to move into the fixed cylinder 18, thereby disengaging from the card slot 20 and releasing the lock on the first installation frame 7 and the second installation frame 8.
