As laser technology continues to evolve, customers are no longer satisfied with machines that can only perform a single task. Today, manufacturers want faster production, cleaner welding results, lower labor costs, and more flexible processing solutions.
This is exactly why the new Relfar 5-in-1 laser welding gun has quickly become one of the hottest topics in the laser industry.
One Welding Gun, Multiple Functions
The Relfar 5-in-1 laser welding gun combines multiple processing functions into one intelligent handheld system.
One machine can complete:
- Laser welding
- Weld seam cleaning
- Surface cleaning
- Handheld cutting
- Pulse spot welding / lithium battery welding

Compared with traditional welding equipment, users no longer need to switch between multiple machines.
This greatly improves production efficiency while saving factory space and investment costs.Dual Swing Technology for Better Welding Results


One of the biggest highlights of the Relfar 5-in-1 welding gun is its advanced dual swing technology. The system supports:
- 7 welding swing patterns
- 8 energy-storage welding patterns
- 10 cleaning swing modes
Different swing patterns create different welding effects, penetration depth, and fish-scale weld appearances.
Operators can easily adjust the welding style according to different materials and applications.
Whether for thin sheet welding, thick plate welding, or precision spot welding, the system delivers stable and beautiful results.
Intelligent Design for Modern Factories
The Relfar welding gun is designed not only for performance, but also for long-term industrial use.
Key features include:
- Intelligent temperature monitoring system
- Lens abnormality alarm within 20ms
- Quick-change drawer-type optical lenses
- Double protective lenses
- Multi-language operating system
The system continuously monitors the status of protective lenses, focusing lenses, reflective lenses, collimation lenses, laser source, chiller, gas pressure, and external safety signals.
This helps users reduce downtime and improve production safety.
Powerful Welding and Cleaning Performance
The Relfar 5-in-1 system supports multiple industrial applications.
Welding Capability
- Carbon steel welding up to 14mm
- Aluminum welding up to 10mm
- Maximum weld width: 12mm
The four-wire feeder system provides fuller weld seams and higher welding efficiency.
It supports single-wire, dual-wire, and four-wire feeding solutions.
Cleaning Capability
The system can efficiently remove:
- Rust
- Oxide layers
- Paint
- Oil contamination
Maximum cleaning width can reach 100mm or more depending on configuration.
The cleaning effect is uniform, efficient, and environmentally friendly.
Ideal for Lithium Battery Welding
The Relfar 5-in-1 laser welding gun is also widely used in lithium battery applications.
It is suitable for:
- EV battery repair
- Battery pack assembly
- Reinforcement rib welding
- Copper-aluminum composite tabs
Compared with traditional welding methods, laser welding offers:
- Faster welding speed
- Better welding consistency
- Stronger weld strength
- Easier operation
Safer and More Reliable
Safety is another major advantage of the Relfar system.
The welding gun includes multiple safety protections:
- Safety lock switch
- Dual-click trigger protection
- Magnetic induction safety switch
- Lens detection alarm system
- External equipment monitoring
These intelligent protections help reduce operational risks and protect both operators and equipment.
The Future of Handheld Laser Processing
Modern manufacturing is moving toward intelligent, multi-functional, and highly efficient equipment.
The Relfar 5-in-1 laser welding gun is not simply a welding tool — it is a complete metal processing solution.
For customers looking to improve productivity, reduce costs, and expand processing capabilities, the Relfar 5-in-1 system offers a powerful competitive advantage.
As global demand for laser processing continues to grow, multi-functional laser welding technology is becoming the new industry standard.
