7 [m] Max. length of optical fiber of welding gun

Productivity benefits

With precise laser beam control, high speed operation, and air cooling, the machine is capable of welding carbon steel, stainless steel, aluminum alloys, and other metals anywhere, anytime—thanks to its portable design.

1. Multiple increase in cutting speed

Approximately 3–10 times faster than traditional methods.

2. High-quality welding

Low thermal load is usually accompanied by minimal deformations, high weld strength and a good appearance of the joint.

3. Easy to operate

The weight of the welding gun is ≤ 0.7 kg, even beginners can easily get started.

3. Savings on overall costs

Saves at least 2 welders, significantly reduces labor and maintenance costs due to the absence of consumables.

Mechanical advantages

The modular machine consists of a bed base, spindle assembly, vertical rack, cross beam, protective metal panels, etc.

1. Completely new design

  • Compact 1.5-2mm thick aluminum alloy body, takes up less than 0.23m² of floor space
  • Small size and easy to transport, net weight: 45-55 kg - about 75% less than other water-cooled models
  • Monoblock type manual welding gun - dust and leak resistant
  • 4 universal casters allow an adult to easily lift the machine

2. Air cooling

Cooling with a fan and air - no need to regularly replace distilled or purified water, no additional devices such as a tank or pump.

3. Adaptation to different working conditions

Extremely low failure rate even at temperatures of -10~40℃ and humidity ≤70% - thanks to the use of CE certified electronic components from international brands.

Advantages of the control system

The control system we developed is multi-functional and equipped with dual controls for quick adjustment of laser power and spot width. This user-friendly interface makes it easier for operators on site.

1. One device — four functions

Flexible switching between welding, cleaning, seam cleaning and cutting

2. Security protection

Protection with temperature/low voltage alarms and more for increased safety

3. 24 interface languages

Chinese, English, Korean, Russian, Japanese, German, French, Italian, etc.

1. 1. Intelligent connection

The I/O auto-start interface is reserved for connecting to the welding robot with just one button press. We aim to make it smarter and more automated. This will bring you a welding experience you never had before.
What is a laser cutter and how does it work?

A laser welding machine is a device used to weld materials. It has a high power density and rapid energy release, making it much more efficient than traditional welding methods. There is no need for secondary processing, even when welding dissimilar materials. The emergence of such machines has been a real breakthrough in welding technology.

Laser welding involves the use of a highly efficient laser beam to locally heat small areas of material. The energy of the laser radiation is quickly transferred into the material by thermal conduction, as a result of which the material melts and forms a weld pool of the required shape.

Today, SENFENG offers more than 10 different models of welding machines for customers around the world.

Depending on the level of automation, manual and robotic models are available.
By type of cooling - air-cooled and water-cooled devices.
Regarding the heat source, laser and arc welding are available.

Customers can choose a standard solution or order custom manufacturing according to their needs.

The main types of welding include: butt welding, surfacing, spot welding, stud welding, T-welding, internal and external fillet welding, and hermetic welding.

Among the advantages of laser welding are deep penetration, narrow weld zone, small heat affected zone, minimal deformation, and high welding speed.

Laser welding uses a laser beam as a heat source. The main welding objects are thin-walled materials and precision parts such as stainless steel, carbon steel, tool steel, copper, aluminum, gold and silver. It can also be used to eliminate defects such as wear, pores, sinks, cracks, scratches, deformation and hardness reduction in workpieces.

The full warranty for the equipment is 1 year. Major components and consumables are replaced according to their actual service life. We also provide original spare parts for users worldwide - with a quotation within 24 hours and delivery within 3-7 business days. Priority in replacing such parts is given to our subsidiaries or local service centers.
