What is the CTC020-HJ2027?
The CTC020-HJ2027 is the largest model in the CTC-HJ collaborative welding arm series. It offers a 20 kg payload and 2027 mm reach for heavy tooling, large fixtures, and long seams.
Key Features
- 20 kg Payload: handles large MIG/MAG torches, heavy sensors, and multi-axis positioner integration
- 2027 mm Reach: covers large weldments and reduces the number of robot repositions per part
- Multi-Process Ready: GMAW, GTAW, spot, and laser welding configurations are available on the same platform
- Rigid Arm Construction: 68 kg self-weight and reinforced joints provide stability for high-deposition welding
Typical Applications
This system is widely used in the following industries and scenarios:
- Large Frame Welding: construction equipment, agricultural machinery, and truck body frames
- Heavy Fabrication: thick-wall steel and multi-pass welding in structural shops
- Long-Reach Assembly Welding: parts up to 2 meters in size where robot repositioning is costly

Frequently Asked Questions
Payload is 20 kg and reach is 2027 mm.
Yes, it includes hand-guide teaching and collision detection. However, risk assessment is especially important due to the larger reach and mass.
Power consumption is 1500 W. A standard 220V single-phase supply is sufficient.
Yes, the CTC020-HJ2027 can be integrated into a mobile welding cart for large-part job-shop work.
