It is suitable for welding applications across multiple industries, including hardware, kitchenware, sheet metal, and precision hardware.

The equipment offers strong compatibility; in addition to stainless steel, it can meet the welding needs of various metal materials such as aluminum, iron, and alloys, making it a versatile and cost-effective solution. With a low failure rate and convenient maintenance—requiring no complex upkeep procedures—it can reliably handle high-frequency industrial production conditions over the long term.

True 5-in-1 Function

● Welding

Laser welding has fast speed, small weld width and depth, small thermal shock area, small deformation, smooth and beautiful weld, high welding quality, no pores, accurate control, stable welding quality, no need for treatment or simple treatment after welding.

It can realize welding at any angle, suitable for welding of planes, straight lines, arcs and any shapes, and can complete welding well in various complex environments. It has high production efficiency and has more obvious advantages than traditional argon arc welding, electric welding and other processes.

● Cleaning

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, and the rust, oxide layer, oil stains, etc. on the surface of the material can be effectively removed without destroying the surface characteristics. It has the characteristics of non-contact, does not require cleaning fluid, and can replace professional cleaning equipment.

● Cutting

Simple cutting can be performed, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.

It can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheets, with a maximum cutting thickness of about 2mm.

● Weld cleaning

It can effectively remove impurities such as oxides, welding slag, oil, dust, etc. generated during welding, making the weld surface clean. This not only helps to improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning has high precision and controllability, and can thoroughly clean the weld surface without damaging the parent material.

● Energy Storage Welding

It can effectively handle welding tasks with high energy demands, ensuring welding quality and consistency. Because it can release a large amount of energy in a short time, energy storage welding is suitable for processing various metal materials, especially in applications requiring high-strength and precision welding.

Product Technical Features

1. One machine with four functions: rapid switching between four modes: Energy storage welding, cleaning, welding, cutting and weld cleaning.

2. The handheld welding gun replaces the previous fixed light path, which is more flexible and convenient, enables long-distance laser welding, and overcomes the limitations of the workbench travel space.

3. The handheld welding head is light and flexible, easy to operate, and can meet welding at various angles and positions.

4. Use infrared positioning for welding head position calibration and position verification during welding to ensure a more beautiful weld.

5. It has the dual protection function of water path and air path (patented technology), which effectively avoids damage to the laser lens or optical components due to operator misoperation, thus greatly reducing the machine failure rate and effectively extending the service life of the machine. The life of consumables.

6. Use infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the welding seam is smooth and beautiful, and it is easy to grind and polish. No post-welding treatment is required or only simple processing is required.

7. Suntop Laser Cleaning Machine is subjected to strict tests and continuous 24-hour laser beam output before leaving our factory to ensure 100% machine stability.
