What Sets a Welding Robot Manufacturer Apart?
Some companies selling collaborative welding arms do not manufacture the arm itself. They integrate a third-party robot platform with a welding torch, which can create support gaps between the arm, controller, and welding process.
CBOXTEC has designed and manufactured complete robot arms in-house since 2021. Harmonic drive joints, EtherCAT controllers, welding-specific kinematics, and application software are developed in Foshan, Guangdong. Factory area: 4,000 m².

Why CBOXTEC Welding Robots
In-House Arm Design & Manufacturing
Every joint module, harmonic drive, servo motor, and EtherCAT controller is designed and assembled in our 4,000 m² factory in Foshan.
Welding-Specific Kinematics
CTC-HJ arms are designed for welding from day one: joint ranges optimized for torch orientation, internal cable routing through hollow wrists, IP65 protection at every joint.
Hand-Guide Teaching
No programming required. A welder grabs the arm, moves it to teach weld points, and saves the program. Job changeover in under 15 minutes for most applications.
Two Ways to Buy
Buy the arm alone and integrate with your equipment. Or get a complete welding cart: arm plus power source, wire feeder, gas cylinder, and mobile trolley — pre-tested before shipping.
Welding Process Support
Application engineers understand welding metallurgy, parameter optimization, and torch selection — not just robot motion planning. GMAW, GTAW, laser, and spot welding support included.

Yes. The CBOXTEC welding cart includes a CTC-HJ arm, welding power source, wire feeder, gas cylinder, mobile trolley, controller, and teach pendant — all pre-wired and factory-tested.
Most simple weld paths can be taught in 15–30 minutes using hand-guide teaching. Complex multi-pass welds may take longer depending on part geometry and quality requirements.
CTC-HJ arms operate on 220V single-phase power. The CTR008-HJ1450 industrial robot typically requires a 3-phase industrial supply due to its 4550 W power consumption.
