Figure 5 As shown, the end cap 1 needs to be welded with two copper tubes 2. Since the end cap is made of iron and the copper tube is made of copper, the two cannot reach the welding temperature at the same time during welding heating. Therefore, the copper tube needs to be preheated first, and then the copper tube is pressed down and welding wire is added to complete the connection between the end cap 1 and the two copper tubes 2. The existing welding tube holder only has a material supporting function and cannot automatically unload after welding is completed. Therefore, a tube holder adjustment mechanism for an automatic welding machine is proposed. Utility Model Content
