Handheld Fiber Laser Welder for Fast, Clean Metal Welding

The Dato DT-HJ is a handheld fiber laser welding machine designed for fast, clean, and low-distortion metal welding. It can weld stainless steel, carbon steel, aluminum, copper, galvanized sheet, and other suitable metals depending on laser power and material thickness.

Compared with traditional TIG or MIG welding, handheld laser welding can reduce heat distortion, improve welding speed, produce cleaner weld seams, and reduce post-weld grinding for many metal fabrication applications.

Key Features

- 1000W / 1500W / 2000W / 3000W laser power options

- Suitable for stainless steel, carbon steel, aluminum, copper, and galvanized sheet

- Clean weld seam with less post-weld grinding

- Lower heat input and reduced deformation compared with traditional welding

- Supports continuous welding and modulation modes

- Lightweight handheld welding gun, about 0.8 kg if confirmed

- Easy operation for sheet metal, cabinets, doors, windows, hardware, and metal fabrication

DT-HJ Handheld Laser Welding Machine Advantages

Fast and Clean Laser Welding

The DT-HJ provides concentrated laser energy for fast welding with a clean weld seam. For many sheet metal applications, it can reduce heat distortion and post-weld grinding compared with traditional welding methods.

Adjustable Welding Parameters

Operators can adjust laser power, welding speed, wire feeding, wobble width, and welding mode according to material type, thickness, joint design, and welding quality requirements.

Handheld Fiber Laser Welder Core Benefits

6 Welding Modes

The DT-HJ supports multiple welding modes for different joint types and welding requirements, including spot welding, continuous welding, fillet welding, groove welding, surfacing welding, and other common applications.

Lightweight Welding Gun

The handheld welding gun is designed for comfortable operation during long working hours. If confirmed, the gun weight is about 0.8 kg.

Stable Machine Structure

The machine cabinet and internal components are designed for stable operation and daily industrial use. Dato can provide configuration details according to your selected model.

Low Noise Operation

The fiber laser welding process is generally quieter than many traditional mechanical welding and grinding workflows. Actual noise depends on auxiliary equipment, shielding gas, and workshop conditions.

Safety Protection

The DT-HJ includes safety features such as emergency stop, overheat protection, grounding protection, and operating status monitoring. Operators should always use proper laser safety glasses, protective gloves, and follow local safety requirements.

Intuitive User Interface

The touchscreen interface helps operators adjust welding parameters, select welding modes, and start production more quickly.

Cleaner Welding Process

Laser welding can reduce filler material use and post-weld grinding for many applications. Fume extraction and proper workshop ventilation are still recommended.

Handheld Laser Welding Safety

Handheld laser welding requires proper safety protection and operator training. Before using the DT-HJ, operators should wear laser safety glasses, protective gloves, and suitable work clothing. The work area should use proper grounding, shielding gas, fume extraction, and safety procedures.

Recommended safety items:

- Laser safety glasses matched to the laser wavelength

- Protective gloves and welding clothing

- Proper grounding and machine inspection before operation

- Fume extraction or workshop ventilation

- Operator training before production use

- Emergency stop and safety interlock checks

DT-HJ Handheld Laser Welding Machine Video

Watch how to set up and operate the DT-HJ handheld laser welding machine. The video can help new operators understand machine connection, parameter setup, welding gun operation, safety checks, and basic welding practice.

Operator training is still recommended before production use.
