Description
The DN - WELD series air-cooled handheld laser welding machine has a compact and small overall design, with a lightweight body, making it easy to carry and use, and can easily adapt to various working scenarios. The welding gun head highlights the advantages of being light and flexible, making it easy to operate. The welding machine is also equipped with an advanced and efficient control system, realizing the centralized control of the welding gun and wire feeder. Different welding processes can be easily retrieved with one key. At the same time, it supports one-key language switching function, which can support up to 19 languages, meeting the diverse user needs.
1. Laser Source: Utilizes a high-performance fiber laser which power can be adjusted flexibly within the range of 10% - 100%, and it can realize continuous light emission and stable laser output with a power stability of ±2%. The built-in air-cooling system eliminates the need for additional cooling equipment, ensuring the portability.
2.Air-Cooled Welding Gun: The pipe-free design allows for greater flexibility in angle adjustment. Weighing only 700 grams, it is 50% lighter than traditional water-cooled welding guns, enabling easy one-handed operation and significantly enhancing productivity in continuous welding tasks.
3.Wire Feeder: Synchronized with the welding gun for simplified operation, it supports "one-touch wire feeding" and "one-touch wire retraction" functions, and also supports dual-channel wire feeding, which can meet different welding needs and further improve the flexibility and efficiency of the welding work.
Applications
Laser Welding is widely used in various industries, such as Shipbuilding, Metal external processing, Auto mobile industry, House hold appliances, Orbital welding, Hardware accessories, Manufacture, Medical equipment, etc

Advantages
Simple Operation, Easy to Learn and Use
•Equipped with a dedicated control system, featuring a user-friendly interface and comprehensive functionality.
•Visualized operation interface with flexible parameter adjustments and simplified operation.
•Supports multi-group process parameter storage; process names can be freely modified, and different processes can be recalled with one-touch access.
Clear Printing, High Efficiency
•Adjustable focus, scanning width, and spot center for enhanced flexibility and convenience.
•Gradual and delay control at the start and end points of the laser ensures consistency in welding initiation and termination.
•Wire synchronization and wire breakage can be adjusted by software, ensuring consistency and seamless connection at the start and end points of welding, as well as automatic wire breakage at the end, significantly saving welding and post-processing time.
Stable Performance, Powerful Functionality
•Real-time monitoring of operational data: Includes safety lock indicators, laser alarm indicators, chiller alarm indicators, gas shortage alarm indicators, and welding head temperature indicators, facilitating status judgment and early warning.
•Professional laser welding gun, weighing only 0.7 kg, lightweight and durable.
•Easy-to-disassemble gun design for convenient maintenance.
Maintenance-Free, Economical and Environmentally Friendly
•Optimized optical, water-cooling, and gas path designs enable the laser welding head to operate stably at 3000W for extended periods.
•Spot diameter adjustment range of 0-8mm, capable of meeting weld width adjustments from 0.83mm to 8mm.
•Wire feeder supports 0.6-2.0mm welding wire, with easy wire breakage functionality and a maximum supported motor cable length of 30 meters.
- 1. Easy to Operate and Maintenance-Free: Simply select the welding material, plate thickness, and lap joint method, and choose whether to use wire feeding. The system will automatically match the optimal parameters. While water-cooled lasers are still waiting to reach their set operating temperature, the air-cooled laser can start welding immediately.
- 2. Cost-Effective and Energy-Efficient: Taking a 1500W laser welding machine as an example, the air-cooled system consumes 1 kW less power compared to water-cooled systems, resulting in significant annual electricity savings. Additionally, there is no need to regularly add purified water or antifreeze, reducing maintenance costs.
- 3.Compact and Portable: The air-cooled laser is small in size and easy to move, making it ideal for multi-position welding on large non-standard equipment. Its portability enhances flexibility in various industrial applications.
