SUP27S Vs SUP37S Welding Head: Key Differences Explained

Understanding the SUP27S and SUP37S Energy Storage Welding Heads

For manufacturers evaluating laser welding tools for new energy applications, two product lines from Wuxi Super Laser Technology Co., Ltd. frequently come under comparison: the Handheld Energy Storage Welding Head SUP27S and the Five in One Biaxial Swing welding head SUP37S. Both carry a 3000W power class and share certain ergonomic design philosophies, yet they are engineered for distinctly different operational contexts. This review breaks down the functional architecture, technical specifications, and application scenarios of each head to help industrial buyers identify which configuration aligns with their production requirements.

Core Functional Differences

SUP27S: A Purpose-Built Energy Storage Welding Solution

The SUP27S was developed specifically for welding in the new energy field. Its design is optimized for thin plate materials, producing smooth and aesthetically pleasing weld seams—an important consideration for battery and energy storage component fabrication where visual and structural weld quality directly affects product reliability.

At the heart of the SUP27S is a two-axis swing mechanism driven by a galvanometer motor that moves the X and Y axis lens in a variety of swing modes, allowing the head to meet various weld seam requirements. The unit also includes an independent process switching button, enabling convenient switching between 3 preset processes for different welding scenarios.

Safety is addressed through an independent safety switch, which adopts a trigger-safety switch linkage triggering design. This mechanism effectively enhances the safety protection level during use, a feature specifically called out for this model.

Ergonomically, the SUP27S incorporates a support structure design that ensures a more comfortable grip with both hands, allowing the welding process to be effortless and stress-free—particularly valuable during extended energy-storage production runs.

SUP37S: The Five-in-One Multi-Process Integration

In contrast, the Five in One Biaxial Swing welding head SUP37S is built around process versatility rather than single-application optimization. As its name indicates, it combines five distinct functions in one head: welding, energy storage welding, platform welding, cleaning, and pass cleaning. These modes can be switched with just one click, consolidating what would otherwise require multiple dedicated tools into a single handheld unit.

The SUP37S is equipped with the version 2.0 Digital Drive Solution, a new-generation digital drive system that increases oscillation frequency by 30% and improves motor positioning accuracy. This digital backbone supports consistent performance across all five operating modes rather than being tuned narrowly for one welding type.

Like the SUP27S, the SUP37S includes an independent process switching button for toggling among 3 preset processes, paired with an operating status indicator light that provides real-time feedback on the system’s operating status. Its multi-functional cable has also been upgraded to shielded twisted pair, delivering stronger anti-interference performance—a detail not mentioned for the SUP27S.

The appearance of the SUP37S has been comprehensively upgraded with an ergonomic support structure design ensuring a comfortable two-handed grip, mirroring the comfort-oriented approach seen in the SUP27S but applied across a broader set of welding and cleaning tasks.

Technical Parameter Comparison

While both heads share a 3000W power class, water cooling, and a recommended air flow rate of 10–15 L/min, several specifications diverge:

• Protective Lens: SUP27S uses a D303mm protective lens, while the SUP37S uses a smaller D182mm lens.
• Focusing Lens: SUP27S is fitted with a D30 F200mm focusing lens; SUP37S uses a D20 F200mm focusing lens.
• Applicable Wavelength: SUP27S operates at 1070±10nm, whereas SUP37S is rated for a slightly broader 1080±20nm range.
• Maximum Spot: The SUP27S specifies a maximum spot size of 15mm, The SUP37S specifies a maximum spot size of 20mm
• Scope of Application: The SUP37S explicitly lists a scope of application of ≤3000W.
• Weight: The SUP27S weighs approximately 1.1kg, slightly heavier than the SUP37S at approximately 1.0kg.
• Collimating Lens and Vertical Focusing Range: Both products share identical specifications here—a D16 F60mm collimating lens and a ±10mm vertical focusing range.

These parameter differences reflect each head’s design priority: the SUP27S’s larger protective and focusing lens components support its thin-plate energy storage welding focus, while the SUP37S’s configuration is tuned to accommodate multiple process modes within one optical housing.

Application Scenario Differences

The SUP27S is positioned for operations centered on new energy component welding, specifically where thin plate materials and weld seam aesthetics are priorities. Its galvanometer-driven swing modes and dedicated safety switch make it suited to repetitive, high-consistency welding tasks within battery or energy storage manufacturing lines.

The SUP37S, by comparison, is designed for environments where operators need to move fluidly between different process types without changing tools. Because it integrates welding, energy storage welding, platform welding, cleaning, and pass cleaning into one head, it serves workflows that combine fabrication and surface preparation steps—reducing the need for separate dedicated equipment. This versatility was demonstrated when Super Laser showcased the SUP37S Five in One Biaxial Swing welding head at the 29th Beijing Essen Welding & Cutting Fair 2026, where it was presented in the context of custom automated turn-key project collaboration with integrators, including on-booth sample welding tests and technical verification.

Choosing Between the Two

For teams whose production is concentrated on new energy thin-plate welding with an emphasis on consistent, visually clean seams, the SUP27S’s specialized two-axis swing and dedicated safety switch offer a focused tool for that specific task. For operations requiring flexibility across welding, cleaning, and platform-based processes—particularly those exploring automated or integrator-driven production setups—the SUP37S’s five-in-one architecture and digital drive enhancements provide broader process coverage from a single gun body.

Conclusion

Both the SUP27S and SUP37S originate from Wuxi Super Laser Technology Co., Ltd.’s broader handheld and automation welding portfolio, which also includes digital drive systems, shielded cabling, and ergonomic housing design as recurring engineering themes across product lines. As the company stated in connection with its appearance at the Beijing Essen Welding & Cutting Fair 2026, Super Laser will keep developing core laser welding products, delivering upgraded handheld welders, platform welding systems, wire feeders, and control systems with enhanced performance, stability, and intelligence, striving to facilitate the efficient, smart, and green transformation of Chinese manufacturing. Understanding the specific functional emphasis and lens/wavelength specifications of the SUP27S versus the SUP37S allows fabrication teams to match the correct tool to their energy storage, platform welding, or multi-process cleaning requirements.
