• Large-diameter pipe welding
• Structural steel fabrication
Features of Welding Rotator
- The rollers’ distance automatically adjusts to accommodate different barrel diameters.
Speed is adjustable via a frequency control system, enhancing operational reliability.
3.Easy operation is ensured with a manual control box.
4.Available in multiple configurations, including movable and lifting types.
5.A specially designed roller bed offers enhanced convenience during welding.
6.Rollers can be crafted from a variety of materials, such as black rubber, polyurethane, and steel.
Maintenance of Welding Rotator
1. This welding rotator needs cleaning before putting into use. And to avoid aging, the rubber rollers should stay away from oils and high temperature. If possible, there should be a specific person to operate and maintain this device.
2. Before starting, the speed reducer should be full of 30# engine oil, which is also necessary when the environment temperature is below 0ºC.
3. The oil inside the speed reducer should be completely replaced after the use of first month, and later, the engine oil can be changed every six months.
4. The roller bed can not be used as the welding ground so that bearings can be prevented from damaging.
