Description
1. Overview of welding robot QJAR QJR6-2000H
The welding robot QJAR QJR6-2000H is an intelligent arc welding robot with a 6kg payload capacity. Featuring an innovative hollow arm and wrist structure, it allows the entire welding cable bundle to be neatly routed inside the robot body. This smart design not only protects the cables from physical wear and damage but also enables the robot to easily maneuver into confined spaces and blind spots that are difficult for human welders to reach.
With a compact chassis weight of 230kg and flexible mounting options—including floor, wall, or ceiling installation—the robot QJAR QJR6-2000H seamlessly integrates into any workshop layout.

- General fabrication & consumer goods: Welding furniture, steel cabinets, rolling doors, and more, delivering a flawless aesthetic finish for commercial products.
4. Key features of welding robot QJAR QJR6-2000H
It is no coincidence that the robot QJAR QJR6-1400H is highly regarded by industry experts. The system packs a powerful punch with premium specs and features:
- Ultra-precise welding: Installed with smart Touch Sensors and Arc Sensors (seam tracking), the robot automatically calibrates the weld path in real-time. This results in flat, uniform, and consistent weld beads that are completely free of porosity and slag spatter, helping businesses save significant time and post-weld cleanup costs.
- Blazing-fast operation: Exceptionally high joint speeds (reaching up to 974°/s on the J6 axis) optimize cycle times and accelerate order delivery schedules.
- Built for harsh environments: Fitted with a specialized protective enclosure, the robot QJAR QJR6-1400H operates with rock-solid stability in the dusty and damp environments typical of fabrication shops.
- Unlimited integration: The system effortlessly syncs with the world’s leading welding power sources and supports plug-and-play expansion with external positioners or linear tracks to easily extend the robot’s working space.
