The SISMA LM-D Series has been developed for professionals who require precise, repeatable manual laser welding with exceptional operator comfort. Built around SISMA’s proven Nd:YAG laser technology, both systems provide stable pulse performance, ergonomic working positions and a spacious welding chamber suitable for everything from jewellery repair to precision component manufacturing.
The LM-D Series is available in two distinct models, allowing you to choose the solution that best fits your workflow and production requirements.
The LM-D is the flagship model, offering advanced features including Smart Spot technology, USB and Ethernet connectivity, recipe management, remote diagnostics and compatibility with multiple viewing systems such as Microscope, Vision and Lynx configurations. It is the ideal choice for manufacturers and workshops that require maximum flexibility, repeatability and production control.
The LM-D Ready delivers the same high-quality laser welding performance in a simplified, user-friendly configuration. Designed for ease of operation, it features an accessible working chamber and intuitive controls, making it an excellent choice for workshops looking for a dependable professional laser welder without the advanced software and connectivity features of the flagship LM-D.

The SISMA LM-D Series is designed for precision manual laser welding where accuracy, control and repeatability are essential. Both models are widely used for jewellery manufacture and repair, dental laboratories, watchmaking, medical devices and precision engineering, producing strong, clean welds while minimising heat transfer to surrounding material.
Typical applications include ring sizing, chain repair, claw rebuilding, jewellery manufacture, dental prosthetics, orthodontic appliances, precision component repair and prototype development. The advanced LM-D is best suited to higher-volume production environments requiring software integration and process repeatability, while the LM-D Ready provides the same welding quality in a streamlined package for everyday workshop use.
