1. Key Features
- The specially designed saddle shaped Curvilinear motion mechanism is easy to adjust and reliable.
- The saddle drop can be adjusted from 0 to the corresponding range, and the machine head can be used for flat rotation welding and saddle welding (under preheating conditions of the workpiece).
- Rotating components are with stepless adjustable rotation speed.
- The horizontal and vertical positions of the welding torch are manually adjusted (non-automatic adjustment), ensuring reliable control.
- It can achieve multi-layer and multi-pass continuous welding.
- The equipment is equipped with a rotating conductive current collection device, and the wires are not entangled during multi-layer and multi-pass continuous welding.
- The rotating conductive device adopts a dual wire and dual brush structure to ensure good conductivity.
- To prevent excessive number of conductive rings, the control system is installed on the equipment body and rotates with the equipment.
- It can work for a long time under the condition of workpiece preheating ≤ 200 ºC.
