3000W Handheld Laser Welding Machine

Suntop laser 3000W hand-held laser welding machine, equipped with dual wire feeders, can use two different diameters or types of welding wire at a time to improve production efficiency. The weld seam has high quality and no porosity, which can reduce and optimize the impurities in the base metal, and can refine the structure after welding. The welding speed is fast, and the weld seam is smooth and beautiful.
Product Model: ST-FW1500H/ST-FW2000H/ST-FW3000H
Laser power: 1500W/2000W/3000W
Single maximum welding thickness: 0.5-8mm

Features of 3000W handheld laser welding machine

1. The operation is flexible and simple, which can realize welding at any position and any angle.

2. Equipped with 10m original optical cable, it is very flexible and convenient for outdoor welding and long-distance welding.

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

4. It has a variety of security alarm functions. The trigger switch is only activated when the soldering copper tip touches the metal, and the safety clip clamps the metal plate. After the welding copper nozzle removes the workpiece, it will automatically lock the lamp. The safety of the machine is very high, which ensures the absolute safety of the operator when working.

5. The system can store a variety of different process parameters, which can be switched at any time through the touch screen according to processing requirements, reducing the time for parameter debugging.

6. Visual instrument and water injection port can be observed at any time during use. At the same time, the touch screen control panel is used to modify the process parameters, which is more intuitive and convenient.

Details of 3000W handheld laser welding machine

1. Laser welding head

Light weight only 0.8KG, flexible and convenient to weld any shape of metal parts, adjustable welding seam width, can be 10 meters long distance welding. Equipped with safety temperature monitoring system.

2. Operation interface

Multi-language intelligent control panel, flexible adjustment of welding parameters, multi-group welding parameter library, light output cumulative timing, etc.

3. Dual wire feeder system

Quickly switch between wire sizes or types by using two different wire diameters or types at once. Automatic wire feeding, more powerful wire feeding, no wire jamming.

4. Laser Source

We use customized minimum 20um core diameter fiber for deeper penetration, laser life up to 100,000 hours, maintenance-free, with Bluetooth capability.

5. Water Chiller

Double cycle water cooling makes the laser source and welding head cooling better, temperature control sensor adopts imported brand.

6. Welding connection fiber optic

10 meters long fiber optic cable with built-in design effectively avoids damage to the fiber and problems caused by moisture, which greatly increases the service life of the laser components.

Advantages of 3000W handheld laser welding machine

1. The welding speed is fast and the efficiency is high, which is 5-10 times that of traditional argon arc welding, which saves labor and reduces the processing cost by about 30%.

2. Concentrated energy, small heat-affected area, no deformation, no blackening, large welding depth, firm welding, fine and beautiful welds without bubbles, no need for grinding.

3. Interactive human-machine interface, easy to operate, no need for professional welders, ordinary people can easily master it in half an hour.

4. It has the advantages of high anti-reflection ability, high efficiency of thin plate welding, deep penetration of thick plate without spatter, maintenance-free, wide operation and frequency modulation range, etc.

5. Emphasis on safety, non-direct radiation, low radiation, no harm to the body, only need protective glasses to filter strong light.

6. It is convenient and flexible to use, the station can be adjusted at any time, no fixed station is required, it is free and flexible, and is suitable for welding in various working environment scenarios.

Single side weld thickness

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times

Dual wire feeder system

3000W handheld laser welding machine dual wire feeder system-Suntop

Use two different diameters or types of wire at once without having to change spools and possibly wire drive related parts. This allows the welding machine to quickly switch between wire sizes or types. This type of wire feeder typically eliminates or greatly reduces the amount of time that changeovers spend on the assembly line, greatly increasing the productivity of the line.

● Our wire feeder with touch capacitive screen, high precision wire feeder.

● 220V drive, more powerful wire feeding, no wire jamming.
