Automated Welding with the Panasonic TAWERS G4 System – A SYN-TIG Case Study

Greater flexibility, precision and productivity in medical equipment manufacturing

At SYN-TIG, our goal is to provide our partners with welding and automation solutions that not only meet today’s production requirements but also create a reliable and flexible foundation for long-term manufacturing operations.

In one of our recent projects, we upgraded the welding process at a Romanian manufacturing facility specialising in medical equipment. The project focused on increasing productivity, improving manufacturing flexibility and ensuring consistently high welding quality.

The solution was built around the Panasonic TAWERS G4 Welding Robot System.

A partnership spanning more than 15 years

What makes this project particularly interesting is that it was not about building an entirely new automation process from scratch.

We installed the first Panasonic robot cells at our partner’s facility back in 2009, followed by another major upgrade in 2014. As production requirements evolved and automation technology continued to advance, the time had come to take the system to the next level.

For this latest project, we upgraded the production line using Panasonic’s latest TAWERS G4 technology.

Our objective was to develop a system capable of handling the production of multiple medical bed frame variants, while ensuring that changeovers between different products could be carried out as quickly as possible and with minimal manual intervention.

Automatic detection for faster changeovers

Flexibility was one of the key requirements of the automated production process.

Before production begins, the system automatically detects the required components and then launches the appropriate manufacturing and welding program for the specific product.

As a result, four different medical bed frame variants can be manufactured on the same production line.

Changeovers between different products can be completed quickly, while the TAWERS G4 delivers the required welding speed, precision and repeatable quality.

This is particularly important in manufacturing environments where multiple product variants need to be handled efficiently without compromising on quality requirements.

Why Panasonic TAWERS G4?

One of the key advantages of the TAWERS G4 is the integration of the welding process and robot control within a single system.

Increased control and processing speeds, combined with optimised communication between the controller and the robot, enable fast, high-quality arc welding.

Compared with previous generations, the G4 features a more compact design while maintaining a high level of reliability. In practice, this means a smaller footprint and more cost-effective system integration.

Another important consideration during the upgrade was making the system easier for operators and engineers to use in their day-to-day work.

Easier programming, less downtime

The TAWERS G4’s touchscreen teach pendant makes robot programming and operation faster and more straightforward.

Another advantage of the system is the potentially longer service life of certain consumables, such as contact tips, compared with previous solutions. This can reduce the number of spare parts that need to be kept in stock and help minimise maintenance-related downtime.

The G4’s offline programming capabilities provide an additional level of flexibility.

Engineers can digitally access production and system data and work on programming individual parts of the welding process while the robot continues to operate.

This is a significant advantage, as programming and optimisation tasks do not necessarily require the entire production process to be stopped.

The result: more flexible and efficient production

As a result of the project, we implemented an automated welding system that supports:

• flexible production of multiple product variants,
• automatic component detection and program selection,
• fast product changeovers,
• high and repeatable welding quality,
• shorter changeover times,
• easier programming,
• and reduced production downtime.

For us, this project is a strong example of the approach we follow at SYN-TIG: we do not simply supply a robot or welding equipment – we build automation solutions tailored to the specific manufacturing process and designed to deliver reliable performance over the long term.

By combining Panasonic technology with our decades of experience in welding technology, robotics and system integration, we can develop solutions that deliver tangible benefits not only in production speed, but also in quality, flexibility and operational reliability.

SYN-TIG – welding technology and automation from a single source

SYN-TIG supports manufacturing companies with the design, integration and support of complete welding technology and robotic automation solutions.

As Panasonic’s long-standing technology partner, our goal is not simply to provide our customers with technology, but to deliver reliable, future-ready systems optimised for their specific manufacturing requirements.
