Welding automation is no longer just for large-scale operations. Today, small manufacturers and job shops have more options than ever — from compact collaborative welding robots (cobots) to high-performance industrial welding robots. With an ongoing shortage of skilled welders, automating welding processes is not just an advantage — it’s becoming a necessity.

OTC DAIHEN makes the transition to automation seamless with a lineup of welding robots and cobots that all operate on the same easy-to-use teach pendant, simplifying programming and integration. Whether you’re looking to supplement your workforce, improve efficiency, or enhance weld quality, our solutions are designed to fit your operation — big or small.

Automating Welding in a Small Shop: Cobots vs. Industrial Robots

For small manufacturers, the challenge is twofold: maintaining quality and efficiency while working within space and budget constraints. That’s where OTC DAIHEN’s automation solutions shine.

Welding cobots are an excellent entry point into automation, providing flexibility and ease of use, while industrial robots offer unmatched speed and precision. No matter which you choose, OTC DAIHEN ensures a smooth transition with a unified teach pendant that makes programming intuitive and a free training for life program for your team.

Why Welding Cobots?

For small shops looking to automate without a major production overhaul, cobots provide the flexibility, reliability, and consistency needed to enhance efficiency while maintaining high-quality welds. These cobots are designed for mobility, making it easy to move them between workstations. Their versatility makes them ideal for small shops handling low-volume, high-mix production or shops looking for a scalable entry point into welding automation.

When to Consider an Industrial Welding Robot

If your shop requires higher-volume production, faster cycle times, or more complex welds, an industrial robot may be the better fit. OTC DAIHEN’s FD Series industrial robots offer superior speed and precision, ensuring consistently high-quality welds at faster rates. With advanced capabilities to handle thicker materials, longer welds, and challenging positions, these robots provide the power and efficiency needed for demanding applications.

The Benefits of Both Cobots & Industrial Robots

Regardless of whether you choose a cobot or an industrial robot, OTC DAIHEN solutions provide:

• Seamless Integration – Both operate on the same teach pendant, making it easy to transition between them.
• Enhanced Productivity – Automating repetitive welding tasks overcomes workforce challenges due to skilled worker shortages and allows your skilled welders to focus on more complex aspects of production.
• Cost-Effective Automation – While the initial investment may be significant, both cobots and robots quickly pay for themselves through increased productivity, improved weld quality, and reduced labor costs.

Choosing the Right Welding Automation Solution

Before integrating robotic welding, it’s essential to define your goals. Ask yourself:

• What problem are you solving? Is it a welder shortage, inconsistent quality, or the need for faster production?
• How will automation fit into your workflow? Consider where the robot will be positioned and how it will interact with existing equipment.
• What training will your team need? With OTC DAIHEN’s Free Programming for Life, your staff can get up to speed quickly.

Need help choosing the right solution? OTC DAIHEN offers a wide range of industrial robots and cobots, and our team of welding and automation experts is ready to assist. Let’s explore the options:

OTC DAIHEN 6-Axis & 7-Axis Arc Welding Robots

6-Axis Robots

With nine models available, our 6-axis robots provide speed, precision, and flexibility for various applications, from welding and cutting to material handling.

• The FD-H5 Compact is ideal for restricted space applications.
• V-Series models feature conventional wrist designs.
• B-Series models offer a hollow through-arm wrist for advanced torch cable management, reducing interference and increasing efficiency.

OTC DAIHEN Cobots: FD-VC4 & FD-VC4L

Both OTC DAIHEN cobot models, the FD-VC4 and the FD-VC4L, make welding easier with plug-and-play setup, intuitive operation, and built-in support features designed for maximum efficiency.

In addition, OTC DAIHEN welding cobots learn through lead-through teaching, which allows operators to manually guide the robotic arm through the desired welding path for precise automation. This intuitive programming method makes it easier for welders to quickly set up and adjust welds.

Here is a breakdown of the key differences between these two cobots:

FD-VC4 Collaborative Robot

• Compact and lightweight, ideal for tight production spaces
• Designed for small-to-medium components
• Working Range: 954mm

FD-VC4L Collaborative Robot

• Extended reach for larger components and more flexibility
• Perfect for environments requiring a wider operating range
• Working Range: 1317mm
