Are you ready to weld and clean at THE SPEED OF LIGHT?


LightWELD laser welding is dramatically FASTER, EASIER and MORE CONSISTENT across a wide range of materials. 

It uses a laser beam or light to join together metals or thermoplastics. This concentrated heat source enables high welding speeds across thin materials and narrow, deep welds between thicker square-edged parts. Some models convert to high-speed cleaning machines at the flip of switch.


  • LIGHTNING FAST: High-speed welding that is 4X faster than TIG, with simple material preparation and minimal post-finishing, plus wobble welding and wire feed options 
  • CONSISTENT QUALITY: High-quality welds regardless of user experience
  • QUICK LEARNING CURVE: Built-in factory presets for welding and cleaning speeds learning; new welders learn in hours and experienced welders realize an immediate increase in productivity
  • MORE MATERIAL FLEXIBILITY: Weld thick, thin, reflective and dissimilar metal welding, even those with different electrical conductivity. Built-in factory presets for all materials and thicknesses.
  • HEAT AFFECTED ZONE: Very minimal
  • WOBBLE WELDING CAPABLE: Up to 5 mm additional weld width
  • PRE- & POST-WELD CLEANING: Up to 15 mm cleaning path

NOTE: This is a Class IV Laser Device which requires special lighting containment to ensure safety.

Light Containment Requirements LightWELD is a Class IV Laser, which means special containment is needed for safety of those not directly involved with laser welding process and not wearing the required PPE, specifically infrared filter safety glasses.  Light containment uses non-light permeable material that will also absorb stray laser without igniting.  Options include: Class IV Curtains made of a heavy fabric that is rated for exposures of 300 WATTS at 1 inch for 90 seconds without igniting.  Curtains can be hung with frames or track mounted on the floor, wall or ceiling. Ceiling mounts can be direct or suspended to work around sprinkler systems or other structures. Prefabricated Enclosures are modular systems with metal components, usually black or gray in color.  Configurations vary based on physical layouts and  functional needs.
