The STR-MASTER SERIES Advantage The next generation in productivity leadership
High Power Laser Source Integration Technology
Open Smart Ecosystem
Multiple interfaces and protocols, 5G + AI cloud upgrade ready, seamlessly compatible with industrial robots for flexible automation.
Industrial-Grade Quality
IP53 protection, vibration- and drop-resistant, shielded against high-frequency and metal dust, built to endure harsh industrial environments.
Smart Process Expert
Proprietary “MASTER” intelligent welding software, integrating AI-driven welding expertise to meet diverse customization needs.
Designed for industrial welding
The Master X Series Laser Welder uses 25 μm small-core laser technology, achieving up to 10 mm weld depth and 8 mm weld width. Compact, lightweight, and built for efficient mobile industrial welding.
laser cleaning for rust removal
The integrated cleaning function ensures a smoother and safer process: no zebra patterns remain after cleaning, delivering a cleaner surface; non-contact laser cleaning avoids grinding, chemical use, or liquid waste, ensuring zero secondary pollution while protecting both the surface and the substrate. It effectively removes oxide layers, paint, oil, and rust from metal surfaces with precision and efficiency.
Beyond Welding, Precision Cutting
Effortlessly cutting materials from 0.5 mm to 15 mm thick, the Master Series is the ideal choice for handling metals of all types and thicknesses. Designed for precision and speed, it delivers clean, consistent, and professional welding and cutting results—whether for simple tasks or complex projects.
Boost Productivity with Automated Welding
The automation welding function maximizes productivity by using high-precision laser welding technology to handle repetitive tasks with consistency and efficiency. It frees skilled welders to focus on more complex applications, while its flexible system design enables easy operation without requiring robotics or programming experience.
Applications
The STR-MASTER Series Laser Welder delivers reliable performance across automotive, construction, machinery, and metal fabrication industries, combining user-friendly operation with enhanced thick-plate welding capability.
Frequently Asked Questions
master-series-handheld-laser-welding
What are the differences between the Master Series, Lite S Series, and STR-HW Series?
The Master Series delivers flagship performance with high power and stability for heavy-duty, thick plate welding. The Lite S Series offers lightweight, zero-barrier operation and portable design, making welding simple anytime, anywhere. The STR-HW Series is our classic, reliable line with balanced performance and broad applications, the trusted choice for general manufacturing and sheet metal processing.
How do I choose the right model for me?
We generally recommend selecting a LITE-S Series model based on the material and thickness you need to weld:
- Aluminum: 1–2 mm → LITE S30 | 2–3 mm → LITE S40
- Stainless Steel: 1–3 mm → LITE S30 | 3–4 mm → LITE S40
- Galvanized Steel: 1–2 mm → LITE S30 | 2–3 mm → LITE S40
- Carbon Steel: 1–3 mm → LITE S30 | 3–4 mm → LITE S40
