Composition Of Welding Gun

Welding guns exporters introduce you to welding gun knowledge. The welding gun is made up of a contact tip, a nozzle, a nozzle joint, a gas screen and a wire feed hose. Contact tip The contact tip is a component that directly transmits current to the wire. The inner hole of the contact tip is in contact with the wire to conduct electricity, and a shielding gas flows between the outer surface of the contact tip and the inner wall of the nozzle. Nozzle, nozzle joint and air screen The contact tip and the nozzle should maintain a good insulation state. The gas screen can make the distribution of the protective gas more uniform and the protection effect is better, and the insulation distance between the contact tip and the nozzle can be increased. Wire feed hose The wire feeding hose is wound by 65Mn steel wire, which is responsible for conveying the welding wire from the wire feeder to the welding gun. As a channel for the wire running, it has a great influence on achieving stable and uniform wire feeding and ensuring the stability of the welding arc. Precautions: 1.Check that the wire feeder is used in conjunction with the specified welding power source and welding gun. 2.Check that the connection between the wire feeder and the welding power source, welding torch and air supply system must be tight and sealed, otherwise the wire feeder may be damaged or the welding process may be unstable. 3.During welding, metal spatter should be avoided from falling on the wire feeder, and the wire feeding wheel and SUS guide cap should be cleaned in time. Serious wear or damage should be replaced in time. 4.The welding gun must be used in conjunction with the specified wire feeder and welding power source. 5.Consumable parts and parts to be replaced should be made of pure parts. 6.Pay attention to the rated load duration of the welding gun when welding. 7.The welding gun must be protected from squeezing, bumping, and strong pulling. It should be placed in a saf....
