For fabricators and new energy manufacturers evaluating handheld tools for thin-plate joining, choosing between a dedicated energy storage welding head and a multi-process integrated head is a decision that directly affects weld quality, workflow efficiency, and operator comfort. Wuxi Super Laser Technology Co., Ltd., operating under the brand Suplaser, offers two distinct solutions in this category: the dedicated Handheld Energy Storage Welding Head SUP27S and the Five in One Biaxial Swing Welding Head SUP37S, which includes energy storage welding as one of its five integrated processes. This guide compares both units based on their documented features and parameters to help buyers align tool selection with production requirements.

Understanding Handheld Energy Storage Welding Heads

Energy storage welding is applied primarily in scenarios requiring precise control over thin plate materials, where weld seam aesthetics and consistency matter as much as joint strength. Suplaser designed both the SUP27S and SUP37S with this application in mind, but each takes a different approach: one is purpose-built exclusively for energy storage welding, while the other integrates it alongside four additional processes.

SUP27S: A Dedicated Energy Storage Welding Solution

The SUP27S was developed specifically for welding in the new energy field. It is optimized for thin plate materials and is engineered to produce smooth and aesthetically pleasing weld seams, addressing a core requirement in energy storage applications.

Product Features

The head operates within a power class of 3000W and uses two axis swing technology, in which a galvanometer motor drives the X and Y axis lens to swing across a variety of swing modes, allowing it to meet various weld seam requirements. An independent process switching button enables convenient switching between three preset processes, reducing setup time between jobs. The design also follows ergonomic support structure principles, ensuring a comfortable grip with both hands so the welding process remains effortless and stress-free during extended use. Safety is addressed through an independent safety switch at the trigger position, using a trigger-safety switch linkage triggering design that enhances the safety protection level during operation.

Technical Parameters

The SUP27S is built with a Collimating Lens of D16 F60mm, a Protective Lens of D30*3mm, and a Focusing Lens of D30 F200mm. It operates at an applicable wavelength of 1070±10nm, with a Vertical Focusing Range of ±10mm and a maximum spot size of 15mm. The recommended air flow rate is 10-15L/min, cooling is achieved through a water cooling system, and the unit weighs approximately 1.1kg.

SUP37S: Five-in-One Biaxial Swing Head with Energy Storage Function

For buyers who require flexibility across multiple welding and cleaning tasks without switching tools, the SUP37S offers a broader process range. Its functions include Welding, Energy Storage Welding, Platform Welding, Cleaning, and Pass Cleaning, all accessible from a single head.

Product Features

The SUP37S also operates at a power class of 3000W and incorporates a version 2.0 Digital Drive Solution. This new generation digital drive solution increases oscillation frequency by 30% and delivers high motor positioning accuracy. The exterior design has been comprehensively upgraded with an ergonomic support structure that ensures a comfortable grip with both hands, keeping the welding process effortless and stress-free. Like the SUP27S, it includes an independent process switching button for convenient switching among three preset processes, complemented by an operating status indicator light that provides real-time feedback on the system’s operating status.

The defining feature of this unit is its innovative Five-in-One mode, which integrates the functions of platform welding, energy storage welding, handheld welding, cleaning, and weld path cleaning, all switchable with a single click. Additionally, the multi-functional cable has been upgraded to a shielded twisted pair configuration, providing stronger anti-interference performance in demanding industrial environments.

Technical Parameters

The SUP37S has a scope of application up to ≤3000W, with a Collimating Lens of D16 F60mm, a Protective Lens of D18*2mm, and a Focusing Lens of D20 F200mm. It operates at an applicable wavelength of 1080±20nm, with a Vertical Focusing Range of ±10mm. The recommended air flow rate is 10-15L/min, cooling is water-based, and the unit weighs approximately 0.97kg.

Comparing the Two Options

Both heads share a 3000W power class, water cooling, and an independent process switching button supporting three preset processes, along with an ergonomic two-handed grip design suited for prolonged operation. The key distinction lies in process scope and lens configuration. The SUP27S is a single-purpose tool concentrated entirely on energy storage welding for thin plates, supported by a dedicated two-axis swing system and an independent safety switch linked to the trigger. The SUP37S, by contrast, broadens the workflow by combining energy storage welding with platform welding, handheld welding, cleaning, and weld path cleaning in one unit, backed by the version 2.0 Digital Drive Solution and shielded twisted pair cabling for interference resistance.

For operations centered exclusively on new energy component welding with thin plates, the SUP27S’s dedicated design and lens specifications (D30*3mm protective lens, D30 F200mm focusing lens, 15mm maximum spot) are tailored to that specific task. For workshops handling varied production lines that require switching between welding, cleaning, and platform welding without changing tools, the SUP37S’s Five-in-One integration offers broader process coverage from a single head.

Market Validation and Industry Recognition

The SUP37S has been demonstrated in a real-world industry setting: Suplaser showcased and deployed the SUP37S Five in One Biaxial Swing welding head at the 29th Beijing Essen Welding & Cutting Fair 2026, where the company conducted on-booth sample welding tests and technical verification as part of custom automated turn-key project collaboration with integrators. Following the event, Super Laser stated its intent to continue developing core laser welding products, delivering upgraded handheld welders, platform welding systems, wire feeders, and control systems with enhanced performance, stability, and intelligence, aiming to facilitate the efficient, smart, and green transformation of Chinese manufacturing.

This market presence is supported by the company’s broader technical foundation. Wuxi Super Laser Technology Co., Ltd. maintains a portfolio of 86 total patents, including 29 invention patents, 36 utility model patents, and 21 design patents, covering optical design and mechanical structures. The company has also been recognized with the “Best Laser Device Technology Innovation Award” at the 2025 China Laser Star Awards and holds status as a “Specialized, Refined, Unique and Innovative SME” and “Gazelle Enterprise.”

Choosing the Right Head for Your Application

Buyers evaluating handheld energy storage welding heads should weigh whether their production environment calls for a focused, single-process tool or a multi-function unit capable of handling several workflows. The SUP27S delivers a purpose-built energy storage welding experience with dedicated safety and swing systems, while the SUP37S extends that same energy storage capability into a five-process platform suited to more varied manufacturing needs. Both units, developed by Wuxi Super Laser Technology Co., Ltd. under the Suplaser brand, reflect the company’s stated positioning of making industrial manufacturing simple and efficient through optical innovation, backed by documented technical parameters and demonstrated deployment at industry exhibitions such as the Beijing Essen Welding & Cutting Fair 2026.
