[0002] During welding, wire feeders often have problems with poor wire feeding and uneven wire feeding, which will bring difficulties to welding and directly affect the welding quality. The wire feeder's clamping wheel should be matched with the welding wire when in use, and the pressure should be adjusted according to the use requirements. It should not be too loose or too tight. If the wire feed wheel pressure is too small, the friction between the wire feed wheel and the welding wire will be too small. Although the prior art has relevant technical means to solve the problem of poor wire feeding by adjusting the wire feed wheel pressure, it is inconvenient to operate and the stability still needs to be improved.
