Flex Lase™ Handheld Laser Systems

Fast. Easy. Precise.

The easy-to-use Flex Lase™ handheld laser welding system puts power, speed and precision at your fingertips. With 2kW of laser output power and a robust package, operators can tackle high-precision welding applications with faster travel speeds, helping to improve productivity without sacrificing quality.

Fast Travel Speeds

Boost productivity with travel speeds up to four times faster than a typical TIG welding process.

Easy Onboarding

Reduce training time and have new operators executing production-quality welds sooner than traditional welding processes.

High-Precision Welding

Reduce material distortion, minimize spatter, and improve process quality with a focused heat input and smaller heat-affected zone. Achieve larger welds using Lincoln Electric’s HyperFill® twin-wire process.

Industry-Driven Design

Have confidence in equipment built to withstand industry demands.

Class 4 Laser Safety Considerations

The Flex Lase™ power source is a class 4 laser instrument that requires careful attention to safety procedures. Read and follow all labels and the Operator's Manual before operating, installing or servicing.

Each organization shall have a qualified Laser Safety Officer (LSO) who is responsible for the safety of operators
Wear proper Personal Protective Equipment (PPE) to avoid eye or skin exposures to laser radiation
Class 4 lasers shall only be operated inside of a Laser Controlled Area (LCA)
Never position yourself or flammable material in the anticipated path of reflection. The proper torch angle is between 30° and 70°

Maintaining safety with handheld laser operations can seem daunting. The requirements are rigorous because the potential hazards are significant, but that shouldn’t scare users from reaping the benefits of the technology. Get informed, get an LSO, and get trained. Read our featured article on handheld laser safety.

If you’re not able to accommodate all of the safety and compliance requirements of handheld laser systems, the Flex Lase cobot embeds them into their design, along with other collaborative robotics and laser benefits. See below for more information!

For further laser welding safety information, see American Welding Society Safety and Health Fact Sheet No. 46 on Handheld Laser Welding Safety, ANSI Z136.1, ANSI Z136.9, IEC 60825-1, and ISO 11553-1.

From Handheld to Automation

Flex Lase Cobot Cart

Flex Lase cobots merge the capabilities of Flex Lase laser systems with collaborative robotics to support high‑mix manufacturing. We’ve evolved handheld laser–based cobotic welding into a fully automation‑ready solution. The laser power source and the cobot arm are controlled via the teach pendant, rather than with separate controls as seen in other systems. The result is a smooth, programming‑ready, highly efficient laser‑welding platform designed for real‑world production environments. Built on a mobile cart, the system can be brought directly to the work area and features an integrated laser enclosure that delivers Class 1–safe operation.

Automation Needs Fume Control Too!

Prism® X-Tractor® systems are specifically designed to remove fumes generated in robotic welding environments. Lincoln Electric can help you meet your fume filtration goals; whether that is to meet OSHA or insurance requirements, retain workers, or simply to have a filtered welding environment.
