Step 1: Draw the Circle According to the Shape and Size of the Coin

The initial step in utilizing our Commarker B4 Laser Engraver for rust removal involves accurately drawing the circle on the affected area, aligning it with the specific shape and size of the coin. This precision ensures that the laser targets the rusted portions with accuracy, facilitating efficient removal.

Step 2: Set the Parameters

Once the circle is defined, configuring the engraving parameters becomes crucial. The Commarker B4 offers a user-friendly interface to set parameters such as power, frequency, and speed. These parameters can be adjusted based on the extent of rust and the metal type, ensuring a tailored approach to each rust removal task.

Step 3: Check the Size and Position Through the Preview

Prior to initiating the engraving process, it is imperative to preview the proposed engraving area. This step allows operators to verify the size and position of the circle, ensuring that the laser is precisely targeted to the rusted region. The preview feature provides a visual confirmation, minimizing the chances of errors and enhancing overall accuracy.

Step 4: Start the Engraving

With the parameters set and the preview validated, the Commarker B4 Laser Engraver is ready to commence the rust removal process. The laser’s focused energy works meticulously within the predefined circle, dislodging rust particles and restoring the metal surface to its original state.

Step 5: Check the Effect and Repeat the Process if Necessary

Following the completion of the engraving process, a thorough examination of the results is essential. If any traces of rust persist, operators have the flexibility to repeat the process. This iterative approach ensures that even stubborn rust is effectively addressed, guaranteeing a comprehensive and high-quality restoration.


In conclusion, the ComMarker B4 Laser Engraver stands out as a pivotal tool in streamlining the rust removal process. Its systematic approach, marked by precision, adaptability, and user-friendly features, ensures a seamless and efficient experience for users. The machine’s ability to navigate the complexities of rust removal with accuracy is a testament to its advanced technology.
