Introduction to Welbee The Short Arc 500

Daihen Corporation has unveiled its latest innovation in welding technology with the introduction of the "Welbee The Short Arc 500". This advanced welding machine is specifically designed to address the challenges faced by the construction steel and shipbuilding industries, providing solutions for improving quality, tackling labor shortages, and fostering environmental consciousness.

Background of Development

The demand for high-quality welding in construction and shipbuilding is on the rise. These industries, which play a crucial role in supporting social infrastructure, are facing persistent problems such as labor shortages and the aging workforce. The transition of skills to the next generation is a pressing issue that needs immediate attention. In this context, it has become vital to enhance quality and productivity, generating a significant need for welding machines that can deliver high-quality, efficient results with ease.

In the current market for thick plate welding machines, various models are available tailored to different operational environments and applications. These include machines suited for continuous operation in automated factory settings, those designed for repair of welding defects, and models that endure outdoor conditions with dust and water resistance. However, the complexity of selecting the appropriate machine from over 25 options has necessitated the reduction to just two versatile models with the culmination of essential features. Thus, the Welbee The Short Arc 500 was born as the definitive welding machine.

Product Features

1. Unmatched Welding Quality
- The Welbee The Short Arc 500 features a new welding mode known as "P-GMA." This allows for exceptional deep penetration on the initial layers of multi-layer welding, ensuring strength across all joints.



2. Durability and Maintenance
- Utilizing an innovative side flow structure, this machine separates precision components from cooling areas to prevent dust from entering, protecting circuit boards from damage.
- It supports long-duration welding by seamlessly integrating with existing automation setups and comes equipped with an advanced water-cooled wire feeding unit and new welding torch (optional).
- Daily cleaning and maintenance can be performed easily through the front air inlet using compressed air, ensuring reliability and reduced breakdowns.
- A 3-year warranty is included for added peace of mind.

3. User-Friendly Assistance Functions
- The machine is fitted with an intuitive LCD panel that supports four languages—Japanese, English, Vietnamese, and Indonesian.
- The built-in "Welding Guide" automatically sets optimal conditions based on the chosen plate thickness and joint shape, simplifying the user experience for anyone.
- For troubleshooting and information, the "Welding Advisor" function provides real-time Q&A support to propose optimal methods directly from the machine.

4. Energy Efficiency
- Users can expect a reduction of up to 20% in CO2 emissions and electricity consumption compared to previous models, enhancing both cost efficiencies and commitment to decarbonization.

5. Multi-Functionality
- The Welbee The Short Arc 500 is versatile, capable of performing four welding modes: DC welding, DC gouging, manual welding, and self-shielded welding, contributing to a reduction in both space and investment requirements.

Outdoor Model - Welbee The Short Arc 500 -Field Edition-

Daihen also offers a specialized outdoor version called the "Welbee The Short Arc 500 -Field Edition-" which features an IP23S waterproof rating and a highly durable structure resistant to salt damage.

• - Its compact and lightweight design enhances portability for outdoor operations, reducing size and weight by roughly 50% and 60%, respectively, compared to previous models.
• - Automatic voltage drop compensation makes it capable of maintaining consistent welding performance over distances of up to 100 meters.
