Longitudinal seam welding machineLongitudinal seam welding machine is mainly used for semi-automatic welding for 1.0 to 2.0 mm thickness electrical water heater tank. The action mode is tank fixed and welding torch moves. The process uses TIG welding and is equipped with an automatic wire filling mechanism. The equipment is suitable for welding such as carbon steel and stainless steel raw metals. The welding power source adopts Miller Maxstar400, the welding length is adjustable from 0-800mm, suitable for the Ф 340 diameter electrical water heater tank.
Water pipe&Sewage discharging pipe welding machine1. The water pipe welding machine is a special equipment for realizing the automatic welding of the tank body and water pipe; mainly completed by the rotation of the welding torch. Adopt MAG welding method, air-cooled welding torch, power supply adopts OTC400 2. Automatic welding of different size structures can be satisfied by adjusting the positioning fixture. 3 The welding station is designed with a lifting bracket, which separates the tank from the conveyor chain during welding.4. The height of the wire feeder should be as low as possible to facilitate the loading of the wire spool. The torch cable passes directly from the center of the shaft of the rotary head, and the direction of rotation is always in one direction.
