The Air-Cooled Handheld Laser Welding Machine is specifically designed for medium and thin metal sheets. It requires no external water cooling, is compact, highly mobile, and easy to operate. It is widely used in kitchen and bathroom hardware processing, outdoor signage installation, home appliance sheet metal welding, metal door and window railing manufacturing, small hardware parts production, automotive parts processing, warehouse racking construction, and other small to medium batch welding scenarios.
From the streamlined contours of the integrated chassis to the ergonomic grip of the handheld welding torch, and the precision internal layout of the enclosure, we spare no detail in our commitment to setting the benchmark for air-cooled laser welding quality.
The air-cooled integrated laser welding machine utilizes a semiconductor laser to generate a laser beam. This beam is transmitted and focused through an optical system to form a high-precision, small spot size. Leveraging the laser’s high energy density, it rapidly melts metal materials to create a molten pool, completing the weld as the beam moves. This process features low heat input and high welding speed, resulting in a minimal heat-affected zone, minimal workpiece deformation, and excellent weld quality.
The equipment breaks away from traditional split-type architectures to achieve integrated design, offering advantages of high efficiency, stability, intelligence, and ease of maintenance. Its built-in intelligent air-cooling system utilizes powerful fans to generate high-speed airflow, continuously dissipating heat generated by the laser head during operation to extend equipment lifespan.
Below is an introduction to the key component advantages:
1. High-Performance Chip Laser
Utilizes high-power semiconductor laser chips for stable output and rapid response, ensuring welding quality while reducing energy consumption.
2. Multi-Rotation Anti-Splatter Black Gold Laser Gun
Features a repeatable rotating protective lens system that effectively minimizes welding spatter, extends lens lifespan, and significantly lowers consumable costs.
3. Intelligent Air-Cooling System
Integrated high-efficiency fan with smart temperature control delivers continuous air cooling without manual maintenance, enabling sustained stable laser operation.
4. Stepper Wire Feeder
Features a worm gear four-wheel-drive stepper mechanism for precise, stable wire feeding with built-in straightening capability, suitable for diverse welding requirements.
5. Schneider Electric Intelligent Control System (France)
Equipped with Schneider’s high-performance control system, supporting multi-scenario parameter adaptation and intelligent operations to enhance overall equipment control precision and reliability.
Kempson Multi-Spin Anti-Splatter Black Gold Welding Torch features dual protection through reusable protective lenses and specialized anti-splatter nozzles with high-temperature alerts. This significantly reduces consumable replacement frequency and costs. Compared to competitors’ fragile configurations, it saves over 150 yuan monthly in consumables and minimizes downtime losses.
Kempson Air-Cooled Integrated Laser Welding Machine features a compact, integrated design with overall dimensions of 0.4 × 0.66 × 0.8 meters. Its small footprint allows flexible integration into various workspaces, significantly reducing workshop layout costs. The built-in intelligent air-cooling system eliminates the need for external water cooling or air supply, enabling plug-and-play operation for efficient and convenient use.
