Introduction
Laser welding guns are an important part of handheld laser welding systems. Different types of laser welding guns have different structures, functions, and application ranges. The right welding gun affects welding operation, process performance, and production efficiency.
I will introduce the main types of laser welding guns, including standard welding guns, upgraded welding guns, and multifunction swing welding guns. At KEMPSON, we often help customers select suitable laser welding guns based on machine type, laser power, welding materials, and production requirements. This guide will explain the differences between each type and how to choose the right solution for your application.
What Is a Laser Welding Gun?
A Laser Welding Gun is the handheld part of a fiber laser welding machine. It sends the laser beam to the welding area and allows the operator to control the welding path and position. The gun is connected to the laser source, optical system, and wire feeder to complete the welding process.
The main parts of a laser welding gun include the laser output channel, protective lens, wire feeding connection, and welding mode control system. The gun design affects welding operation, lens protection, and process performance during production.
Laser welding guns are made for different machine types and welding conditions. Standard models are used for regular metal welding, while multifunction models are used for high-power welding, precision work, and special processes. KEMPSON laser welding guns support wire diameters from 0.8–2.0 mm for different welding applications.

How to Choose the Right Laser Welding Gun?
Choosing a laser welding gun depends on the welding machine type, laser power, material, and production requirements. The right welding gun affects welding quality, operation efficiency, and equipment performance.
Match the Welding Gun with Laser Power and Machine Type
The welding gun must match the laser source and machine configuration.
- Dual-gun laser welding machines
Use the KEMPSON Black Gold Generation 1 Welding Gun. It is designed for stable continuous welding and welding-cleaning integrated machines. - Standard single-gun laser welding machines
Use the KEMPSON Black Gold Generation 2 Welding Gun. It supports more convenient operation and is suitable for different materials and welding tasks. - 6000W high-power machines and special models
Use the KEMPSON Multifunction Swing Welding Gun. It is designed for high-power welding, ring beam systems, and liquid cooling machines.
Choose Based on Welding Application
Different welding tasks require different gun functions.
Standard Metal Welding
- Choose a basic laser welding gun.
- Suitable for stainless steel, carbon steel, and regular metal fabrication.
- Focuses on stable operation and long-term production.
Different Materials and Thicknesses
