JH620-1800-H Heavy-Duty Welding Robot: 20 kg Payload, 1,800 mm Reach, IP67 Arm

JH620-1800-H is the highest-payload model in HCNC Group's JH series. This heavy-duty welding robot carries 20 kg with a 1,800 mm working radius and ±0.05 mm repeat positioning accuracy, giving production welding cells the capacity for heavy torches, wire feed equipment and demanding duty cycles.

Key Features of the JH620-1800-H

• 20 kg payload, the highest in the JH series.
• 1,800 mm working radius, balancing reach and rigidity.
• Robot arm rated IP67; robot body and controller IP54.
• Standard welding power source, torch and accessories with EtherCAT bus control.
• Supports synchronized robot-positioner welding for production lines.

Why Choose the JH620-1800-H for Robotic Welding

At 20 kg, the JH620 has the most capacity in the series for water-cooled torches, anti-collision devices and wire feeding equipment, so tooling choices are not limited by the robot.

An 1,800 mm working radius covers most medium to large workpieces, while the series is designed for rigidity, speed and motion responsiveness. It is a balanced option when long reach is not the first priority but load capacity is.

The JH series supports synchronized robot-positioner welding, flying arc ignition for faster cycles, arbitrary jump and step-back check for easier debugging, and batch parameter editing for faster programming.

The system checks weld commands intelligently and offers multiple safety modes to reduce collisions. An intuitive icon-based interface supports quick teaching and programming, with tools for versatile parameter editing and debugging.

• Production-line MIG/MAG welding with positioners
• Heavy torch and water-cooled torch welding applications
• High-duty-cycle robotic welding cells

1. Easy to use: 

Operation with icons, high efficiency in teaching welding points and debugging, and realizing blind operation for the operator without robotic operation knowledge.

2. Intelligent instruction check

Automatically check whether the user program welding instructions are correct or not. 

3. Digital communication

The robot and welding machine realize high-speed full-digital communication control, which can make a beautiful welding appearance and easy operation.

4. Intelligent autonomous swing plane selecttion

It supports the dual functions of automatic determination and user-independent designation of the swing plane, expanding the application range of weaving welding.

5. External axis coordination

Support the robot-external axis coordination function of up to 3 axes to improve welding quality and efficiency.

6. Production statistics

Develop special production statistics instructions to support data collection and production statistics functions to save costs.

What is the payload of the JH620-1800-H welding robot?

The payload is 20 kg, the highest in the JH series, with a working radius of 1,800 mm and ±0.05 mm repeat positioning accuracy.

When should I choose the JH620 over the JH615?

Choose the JH620-1800-H when payload capacity matters most, for example with heavy torches and feed equipment. Choose the JH615-2000-H when you need the longest reach (2,000 mm).

Does the JH620 support welding with a positioner?

Yes. Synchronized robot-positioner welding is supported, which suits production-line welding.

A welding power source (analog and EtherCAT bus control), a welding torch (air-cooled, water-cooled or anti-collision), welding accessories and an external button box are standard equipment.
