It can enhance the overall sense of technology of the welding equipment.

[0068] It should be understood that the light strip 207 is also connected to the integrated circuit in the adjustment knob 10, and the brightness of the light strip 207 can be adjusted by rotating the adjustment knob. That is, as the value displayed in the numerical value display area 201 increases, the brightness of the light strip 207 also increases; that is, as the value displayed in the numerical value display area 201 decreases, the brightness of the light strip 207 also decreases;

[0069] Further, the adjustment knob 10 can be a cylindrical structure, and vertical stripes for increasing friction are arranged on the side surface of the cylindrical structure.

[0070] In this embodiment, the numerical values of the welding equipment are displayed in the numerical value display area 201 provided in the display module 20, the unit display area 202 displays the units corresponding to the numerical values, and the first function display area 203 and the second function display area 204 display the current working functions of the welding equipment. At the same time, an abnormal indication area 205 is provided to prompt that the welding equipment is currently in an abnormal working state, and an electric shock prevention indication area 206 is provided to prompt the welding equipment to turn on or off the electric shock prevention function. By providing vertical stripes on the side of the adjustment knob 10, the friction is increased to facilitate rotation and adjustment. Through the light strip 207, the brightness of the light emission can be changed as the adjustment knob rotates, enhancing the visual atmosphere effect and improving the technological sense of the overall welding equipment. The above functions are integrated in the display module 20 and then integrated with the adjustment knob 10 to reduce the area of the control panel. This solves the problem in the prior art that the continuously increasing area of the control panel makes it difficult to arrange civilian welders and affects the design.

[0071] In addition, an embodiment of the present invention further provides a welding equipment, which includes the above digital screen knob. Refer to Figure 3 , Figure 3 which is a schematic structural diagram of the welding equipment of the present invention.
