LM-D
Desktop version with a front opening to the working chamber and the 10-inch touchscreen HMI.
SISMA LM-D is a desktop manual laser welding system for high-precision metal processing and precious metals, with a 10-inch touchscreen, an optional Nano Spot and a FLEX version for jewelry and industrial work.

The SISMA LM-D series is a desktop manual laser welding system for high-precision processing of metals. It was developed from customer feedback, with attention to performance and ergonomics, and it is suitable for working precious metals.
Two models are available, LM-D 230 and LM-D 260, both with a Nd:YAG laser at 1064 nm, pulse durations from 0.55 to 25 ms and a pulse repetition rate up to 50 Hz. The LM-D 230 delivers 230 J maximum pulse energy and 9 kW peak power; the LM-D 260 reaches 260 J and 10.5 kW.
The 10-inch touchscreen HMI shows only what the operator needs. The optional Nano Spot reduces the spot size to 0.05 mm for micro-welding, and Velvet Spot on the LM-D 230 gives stable, constant pulses across the full power range from the first shot.
The machine has a small footprint with wide access to the working chamber, and it is also available in a FLEX version with fringes.
