RJH605 Arc and Spot Welding Robot Main Features

Stable speed, excellent accuracy

Arc welding robot HNC-RJH605 adopts HuazhongCNC’s new generation of the controller and teach pendant. With excellent motion control and large-scale space design, it achieves high reliability and excellent cost performance in welding applications.

Powerful and excellent performance

The hollow arm is adopted. The arm is light in weight and compact in structure, which effectively eliminates the interference of the welding gun cable with the workpiece and peripheral equipment when working in a narrow space, easier to ensure the best posture of the welding gun and improving the wire feeding stability.

Simple to use, easy to program

A humanized, efficient and concise welding process package is provided, as well as professional and customizable services, making novices without welding experience can easily get started, greatly improving efficiency and reducing labor costs

Quality service, efficient after-sales

Remote access monitoring is provided for the user to view the running status of the robot in real-time so that the fault can be solved; it has a professional welding team providing professional welding technical support; dozens of support points for 6 major companies distributed throughout the country, providing quality services 24 hours a day
