300W Laser Rust Removal Machines | Handheld Laser Rust Removers

Display of Operating Interface

HANTENCNC’s pulse laser rust removal machines have 9 cleaning modes and can show a live-time status. You can adjust the settings for various cleaning needs.

Our pulse handheld laser rust removers will provide error message notifications, making it easy to control and manage the laser rust removal machines.

Portable and Lightweight

Engineered for demanding applications, the HANTENCNC 300W laser cleaning gun combines robust power output with a user-friendly control system.

This configuration delivers precise, efficient cleaning performance, meeting the requirements of diverse industrial maintenance and surface preparation tasks.

The 300W laser cleaning gun weighs less than 1.25kg, so you can use it for a long time effortlessly.

Faster scan speed – 25% improvement

We bumped the max scan speed from 30,000 to 40,000.
Maximum scan speed is now 40,000, which is a 25% increase.
Most other laser cleaning machines in China are still at 30,000.
At 40,000, job time is noticeably shorter.
Same cleaning result. Less time waiting.

Anti-interference Design

The 300W laser cleaning gun’s anti-interference ability is improved through measures such as signal reinforcement, signal shielding layer, galvanometer encapsulation, and metal shielding shell design.

Alarm Records for Troubleshooting

HANTENCNC’s laser cleaning system stores alarm records. Users can check historical alarm data at any time.

• Distance alarm – triggers when the laser distance sensor detects the head is too close or too far from the workpiece.

• Chiller alarm – high temperature, low flow, compressor not starting, etc.

• X-axis / Y-axis motor alarm – these two alarm types help HANTENCNC support technicians determine whether the issue is with the motor or the control system, speeding up fault resolution.

Power-on Time Tracking and Reset for Rental Use

The device automatically tracks and displays total power-on time.
This is designed for customers who rent out laser cleaning machines, often charging by the hour or day.
The power-on time serves as a billing reference.

Before renting the machine to the next customer, the user can enter a password to reset the timer to zero.
This makes it easy to track usage for different renters.

Our laser cleaning head features a dust-sealing design for the external optical path and a ring air nozzle that creates an air curtain at the front end of the field lens.

That effectively prevents dust and impurities generated during the cleaning process from entering the laser cleaning head, reduces equipment downtime caused by impurity interference, and thus enables continuous, efficient cleaning.

Laser Distance Sensor and Focus Display

HANTENCNC’s laser cleaning head includes a built-in laser distance sensor. It constantly measures the distance to the workpiece.
If the distance is too close or too far, the screen shows “8888”. This indicates the distance is invalid for laser firing.
In this state, the laser will not emit — even if the trigger is pulled.
This prevents accidental firing when the head is not at the correct working distance.
The screen also displays the real-time distance to the focal point within the valid range, helping the operator quickly find the correct position.

Screen lock – No More Accidental taps

Tapping the lock icon on the screen darkens and locks the display.
No operations are possible while locked.
This prevents accidental parameter changes or machine operation caused by unintended screen contact during work.

Automatic Laser Shut-off Timer

When the laser fires continuously for a set time (e.g., 30 seconds), the system automatically cuts the laser output.
This happens even if the trigger is still pressed.
This reduces equipment wear and safety risks from prolonged continuous output.

Emergency Stop Button

HANTENCNC’s 300W laser cleaning gun equips an emergency stop button, which is a safety lock that stops the machine instantly in an emergency to protect people and equipment.

When pressed, it immediately cuts power, forcibly terminating laser output and all operations.
