What is the CTC007-HJ1077?
The CTC007-HJ1077 is a 6-axis collaborative welding robot arm with a 7 kg payload and 1077 mm reach. It uses harmonic drive joints, an EtherCAT bus controller, and hand-guide teaching. The compact footprint makes it suitable for small welding cells and bench-mounted jigs.
Key Features
- Hand-Guide Programming: operators manually guide the torch to teach points; programs can be saved and recalled
- IP65-Rated Joints: all six joints are sealed, allowing use in workshops with weld spatter, dust, and coolant mist
- Internal Cable Routing: welding cables and gas hoses pass through the hollow wrist, reducing snagging
- Collision Detection: built-in torque sensing stops the arm on contact, supporting collaborative operation
Typical Applications
This system is widely used in the following industries and scenarios:
- Small Part TIG Welding: stainless steel brackets, frames, and housings under 7 kg
- Job-Shop Batch Work: repeated short runs where programming time must stay under 15 minutes
- Assembly Welding: MIG/MAG joining of thin-gauge steel and aluminum components

Frequently Asked Questions
Payload is 7 kg and reach is 1077 mm. These specifications suit small-to-medium weldments and compact jigs.
No. The arm is sold as a standalone unit. It can be paired with a customer-supplied power source or ordered as part of a welding cart package.
GMAW (MIG/MAG), GTAW (TIG), and laser welding are supported depending on the end effector and power source selected.
Hand-guide teaching is the primary method. Operators move the arm to the desired positions and save the path.
