Transform the way you weld.

nexAir is proud to offer LightWELD, an innovative tool that enables dramatically faster welding. Compared to MIG or TIG, LightWELD is easier to learn and operate and provides consistent, higher-quality results across a wider range of materials and thicknesses.

What’s more, LightWELD leads to minimal distortion, undercut, or burn-through. LightWELD minimizes the heat-affected zone dramatically and reduces the need for traditional post-processing grinding. Cut down the time you spend polishing, create fewer scraps, and lower your total cost per part with LightWELD.

Discover how LightWELD is revolutionizing the welding industry.


Simple Installation and Operation

220V Power
Workpiece Clamp
Standard Gas

Clearly labeled rear connections make getting started fast and easy. Laser delivery, gas, and gun control are pre-wired in a 5m (optional 10m) cable. Just plug in the power cord and gas connection, attach the clamp to your work surface and you are ready to go. An ethernet computer connection provides access to advanced parameter settings to fine-tune and save process parameters.

Advantages and Capabilities

TIG welding can generate extreme heat that deforms thin materials, and produces poor visual finishes. Welding copper is difficult and welding metals of dissimilar thicknesses is limited.

MIG welding requires consumable wire, material pre-cleaning and beveled joints for full penetration of thick metals. Travel and work angles are limited and vertical positions are extremely challenging

Unlike traditional methods, welding fixtures are simpler or not needed with LightWELD. Metals do not need to be pre-brushed or ground completely clean, and even novices can reliably weld materials with dissimilar thicknesses and high/low electrical conductivity.

LightWELD welds dissimilar metals of different thicknesses with ease and creates aesthetic high-strength joints with minimal or no consumable wire.

Nothing shows the power of the LightWELD like seeing it in action.

Witness the power of LightWELD for yourself.


LightWELD makes welding simpler than ever. With 74 stored preset and user-defined process parameters, even novice welders can be trained and welding in a matter of hours.

The LightWELD is easily adjusted thanks to intuitive controls that give users the power to quickly dial in weld settings to their optimal level for various materials and thicknesses.

Select stored modes provide up to 2500 W of high peak power for even greater welding capability.

LightWELD Process Automation & Programmability

  • Enjoy predefined welding parameters for high-quality, consistent welds.
  • Reduce training and production costs as even novice welders are trained and welding in a matter of hours.
  • Maximize efficiency with simple controls and 74 stored modes and user-defined process parameters.
  • Save and recall user modes as needed, including customizations for laser power, wobble width and frequency.
  • Switch rapidly between simple modes to tackle different material-thickness combinations.
  • Store parameters so that novice welders can achieve the same high-quality, consistent welds as seasoned operators.

Compact Handheld Welding Gun
Why waste time with unwieldy tools? The LightWELD’s handheld welding gun is compact and ergonomic. It’s proven to be the most comfortable, well-balanced and easy-to-use gun on the market. Thanks to its light weight and built-in wobble functionalities, operators can produce high-quality welds consistently and safely throughout the day with its 2-step trigger.

Built-in Wobble Welding for Increased Productivity

  • Select the correct frequencies for simple, on-the-fly control of up to 5 mm of additional weld width.
  • Create highly aesthetic seams and welding of parts with poor fit-up.
  • Preprogram and save wobble parameters and recall settings on demand as needed.
  • Create wider & highly attractive seams up to 5mm with wobble welding.

Optional Wire Feeding Package

  • Extend laser welding applications to poorly fit-up parts with wire welding capabilities.
  • Use for low carbon steel, stainless steel, aluminum, non-ferrous metals and alloys.


LightWELD XR delivers a higher-brightness beam for welding an extended range of materials and thicknesses up to 0.250” (6.35 mm), including reflective materials. Welding and cleaning materials such as titanium and copper are easy with LightWELD XR.


LightWELD XC provides additional functionality of pre- and post-weld cleaning with the same high-quality welding capabilities of the LightWELD 1500 system.

LightWELD 1500

The most cost-effective solution for laser welding steel, stainless steel, and aluminum up to .160” (4mm) thick. LightWELD 1500 can be paired with a wire feeder, but does not have any cleaning capability.
