As laser welding evolves toward higher power and greater intelligence, a long-overlooked truth is emerging: no matter how powerful the laser source is, it cannot counteract even a slight hand tremor from the operator.Traditionally, dual-oscillation laser welding torches suffered from poor heat dissipation, rapid component aging, and bulky bodies that caused wrist discomfort during extended operation.

To overcome the long-standing industrial dilemma — dual oscillation inevitably means heavy weight, and light weight compromises stability — Qilin Laser established a dedicated R&D team. After two years of in-depth research and development, we achieved a breakthrough through disruptive innovation.

At the Shanghai Laser Optics Expo on March 18, we will officially launch the world’s benchmark lightweight single/dual-oscillation handheld laser welding torches: DWS20 (0.3kg) and BWS20 (0.4kg).Integrated with a brand-new intelligent control system for free mode switching, they truly embody the concept:Light as the palm, intelligence at your fingertips.

——Industry pain points: Heavy torches cause operator fatigue and complicated operation.

DWS20:Ultra-lightweight at only 0.3 kg (equivalent to a can of cola), specially designed for high-frequency splicing and thin-sheet welding.

BWS20: Ultra-light dual oscillation welding torch, weighing only 0.4 kg. Delivers uniform 0.2 mm fish-scale weld beads with porosity rate ＜ 0.3%.

No more complicated menus!

DWS20/BWS20 supports quick switching among six welding modes: pulse, continuous, fish-scale, segment, spot, and energy storage.

Simply tap on the screen icons to instantly adjust power, frequency and wire feeding speed, with all parameters clearly displayed at a glance.

Built-in memory function automatically stores frequently-used welding programs.

Daily operation: Built-in air cooling enabled, no external water chiller required, 60% power saving, desktop-ready deployment.

Heavy-duty continuous welding: Connect to external water cooling to ensure stable equipment operation, enabling worry-free 24/7 nonstop working.

Plug-and-play operation: Equipped with standard Mini QBH interface, compatible with mainstream lasers for instant connection. Zero modification cost, ready to weld right out of the box, truly realizing lightweight operation yet heavy-duty performance.

——Behind the Technology: Lightweight and Intelligence, Derived from System-level Innovation.

All models feature a high-strength aluminum alloy body, achieving an optimal balance of lightweight construction and industrial-grade durability.

Forward center-of-gravity design reduces holding torque by 50%, delivering natural handling akin to holding a pen.

Excellent thermal conductivity effectively suppresses temperature rise and extends the service life of core components.

——Industry Significance: From "machine-centric" to "people-centric"

The launch of DWS20 and BWS20 marks that handheld laser welding has entered a new "intelligent manufacturing" stage:

Lowering the skill threshold: Newcomers can get started in 10 minutes, alleviating the "labor shortage" in the manufacturing industry;

Improving flexible efficiency: One torch with multiple functions, adapting to the rapid switching of multiple materials and multiple processes;
