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°
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.
