[0002] An automatic welding machine is a device used to perform welding operations. It can automatically perform the welding process, improve efficiency and accuracy, and reduce dependence on operators. Automatic welding machines can use different welding methods, including arc welding, laser welding, plasma welding, etc. The selected welding method usually depends on the specific application and requirements. Automatic welding machines are equipped with advanced automation systems, including control systems, sensors and actuators. These systems work together to ensure the accuracy and stability of welding. Automatic welding machines control the movement of welding guns or welding heads through actuators to ensure the consistency of welds during the welding process. Actuators usually use precision motors or hydraulic systems. To ensure the stability of the workpiece during welding, automatic welding machines are usually equipped with workpiece clamping systems, which help prevent the workpiece from moving or deforming during welding. Automatic welding machines are widely used in manufacturing, especially in mass production or fields with high requirements for welding quality. The use of automatic welding machines can improve production efficiency, reduce labor costs, and improve the consistency and quality of welding.

[0003] When using an automatic welding machine for welding, sparks and residues will fly, causing harm to the operator and the surrounding environment, and posing a safety hazard.
