Features of handheld laser welding gun

1. Use infrared positioning for calibrating and verifying the welding position in the welding process. This will result in more accurate welding positions and more beautiful weld seams.

2. The machine is equipped with a high precision wire feeder that has a touch capacitive screen, a 220V drive, automatic wire feed, stronger wire feed, and no wire jam.

3. The handheld welding head is self-developed and is light and delicate, making it easy to operate and allowing for welding at any angle.

4. The machine is equipped with a 10m imported optical fiber, which overcomes the limitation of workbench space. This allows for flexible and convenient outdoor and long-distance welding.

5. The machine has multiple safety alarm functions. The welding copper nozzle is only effective when it touches the metal, and the safety clip clamps the metal plate when the trigger switch is effective. Additionally, the welding copper nozzle will automatically lock the light after moving away from the workpiece. This ensures high safety for the machine and guarantees the absolute safety of the operator during work.

6. The machine has a double protection function for the water and gas circuit (patented technology). This effectively prevents damage to the laser lens or optical components due to operator misoperation, reducing the failure rate of the machine and extending the life of consumables.

Details of handheld laser welding gun

1. Laser cleaning head

Light weight only 0.8KG, flexible and convenient to weld any shape of metal parts, adjustable welding seam width, can carry out 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. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, supporting stainless steel and aluminum wire of 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm diameter.

4. Laser Source

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

5. Water Cooler

Double circulation water cooling makes the laser source and weld head cooler, temperature control sensor adopts imported brand.

6. Welding connection fiber

10 meters long fiber optic cable built-in design, effectively avoid damage to the fiber and the problems caused by moisture, greatly improving the service life of the laser device.

Advantages of handheld laser welding gun

1. The integrated structure design of the entire machine allows for a small equipment footprint and is equipped with large universal casters, making it easy to transport.

2. The welding speed is fast, resulting in high efficiency that is 5-10 times greater than traditional argon arc welding. This saves labor and reduces processing costs by approximately 30%.

3. The interactive human-machine interface makes operation easy, eliminating the need for professional welders. Ordinary individuals can easily master it within half an hour.

4. It possesses several advantages, including high anti-reflection ability, efficient welding of thin plates, deep penetration of thick plates without splatter, maintenance-free operation, wide operational range, and frequency modulation capabilities.

5. Safety is emphasized, as it does not emit direct radiation and has low radiation levels that do not harm the body. Protective glasses are the only requirement to filter out strong light.

6. The energy is concentrated, resulting in a small heat-affected area, no deformation, no blackening, a large welding depth, strong and aesthetically pleasing welds without bubbles, eliminating the need for grinding.

Other optional functions of handheld laser welding gun

Cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, effectively removing rust spots, oxide layers, oil stains, etc. on the material surface without damaging the surface characteristics. It is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.

Cutting function

Simple cutting is possible, 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 bead cleaning function

It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.
