Arc Welding Robots


All Nachi/OTC Daihen welding solutions are seamlessly integrated with plug-and-play CAN-bus interface and easy to use menu driven welding parameter setup directly through the robots’ teach pendant. All welding components are OTC, which makes it easy to select the correct equipment for the job to ensure component compatibility and interface quality. Nachi FD series robots, equipped with OTC welding technology, can perform GMAW, FCAW, GTAW and PAC processes on a wide variety of materials. FD Series manipulators are extremely fast, accurate and hold exceptional path linearity, designed from the ground up with welding process efficiency in mind.

Nachi Robotics offers complete turn-key welding solutions.

Nachi offers the most advanced welding technology available.


The WelBee Series power sources feature the welding industry’s first Nanotechnology components. OTC has developed the proprietary LSI Nanotechnology chip providing the fastest arc monitoring feedback of any welding power source on the market today. Ultra-fast arc monitoring and feedback drastically reduces spatter, improves arc stability and increases welding travel speeds. Welbee power sources also offer a completely sealed design to eliminate dust intrusion into electrical components, minimizing maintenance requirements and drastically improving reliability in harsh production environments.

Using an optional Android tablet app, the tablet can remotely control welding machine settings, monitor critical process variables, troubleshoot, backup, as well as maintain a welding condition database. The optional weld data monitoring system allows the user to remotely monitor and document all essential variables of the welding process to aid in quality control and product traceability. Built in the USB port on the front of the welding machine, allows the operator to easily copy welding procedures from one machine to another without additional programming.

WelBee power sources also offer several helpful features to manage and control welding processes.


Improved Productivity

Variety of Sensing Solutions

These sensing solutions, which allow the user to locate and track weld joints on complicated or unrepeatable components, include: touch, high voltage touch, through-arc seam tracking, laser search, high speed laser search and laser seam tracking. Combine sensing solutions with synchronized motionmulti-unit control or slider units to maximize application flexibility.

Enhanced Flexibility

Flexible Power Supplies

Nachi robots are not solely limited to OTC Daihen power supplies. If you already own your welding equipment, or would prefer to use another brand, Nachi robots can be integrated with any robotic grade power source on the market.

Improved Weld Quality

Accommodates Production Welding Needs

NRS offers 14 models of OTC Daihen welding power supplies, each having it’s own unique benefits. The D-Series welding power sources include the DM350, DM500, DP400, DP400R, DP500, DL350, DW300, DA300P and D12000.
