Technical Field
[0001] The utility model relates to the technical field related to arc welding, in particular to a wire take-up device for an arc welding machine. Background Art
[0002] Arc welding refers to the use of electric arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into heat and mechanical energy required for welding, thereby achieving the purpose of connecting metals. In the arc welding process, an arc welder is usually required. Arc welding machines are divided into different forms of arc welding machines according to different uses. According to the welding method, they are divided into stick arc welding machines, submerged arc welding machines and gas shielded arc welding machines. According to the type of electrode, they can be divided into two categories: consumable electrode and non-consumable electrode. According to the operation method, they can be divided into manual arc welding machines, semi-automatic and automatic welding machines. According to the arc welding power supply, they can be divided into AC arc welding machines, DC arc welding machines, pulse arc welding machines and inverter arc welding machines. However After most arc welding machines are operated, the operators simply wind the welding wire around the welding machine body, which makes subsequent use more cumbersome and the winding increases safety hazards. For example, certain switches may be triggered during the winding process, resulting in danger during the subsequent plugging process. The operators' welding wires are all opened and scattered on the ground. The welding wires pulled on the ground not only bring risks to the operating environment, but also cause the welding wires to be stepped on. The welding wires are easily damaged if they are stepped on for a long time, which shortens the use time of the welding wires and also brings safety hazards. In this regard, the utility model provides a wire taking-up device for an arc welding machine. Utility Model Content
