A laser welder’s power rating sets how thick a material it can weld in a single pass and how fast it runs — so choosing the right wattage is the key decision. Maker-backed, our handheld fiber welders span 800W to 3000W, water-cooled or air-cooled, for everything from thin sheet to heavy structural joints.
What Is “Laser Welder Power”?

Power (in watts) is the laser energy delivered to the joint. More power means greater single-pass penetration and higher welding speed, but also higher power-supply and cooling requirements. The goal is to match power to your thickest material and duty cycle — not simply to buy the highest number.
Key Specifications & Performance
| Power class | Cooling | Indicative max single-pass (SS) | Best for |
|---|---|---|---|
| 800–1000W | Air | ≤3.5 / ≤4.5 mm | Light sheet, portable |
| 1500W | Air or water | up to 6.5 mm (air) / 3 mm (water, continuous) | General fabrication |
| 2000W (single/double wire) | Water | 5 mm | Higher speed, continuous duty |
| 3000W | Water | 7 mm (8 mm with 4000W gun head) | Thickest joints, heavy duty |
Max single-pass, material-dependent; continuous-duty figures available on request. Water-cooled is rated for sustained operation; air-cooled prioritizes portability and wider ambient range.
Applications & Use Cases
Choose your power class: 1000W–1500W for general work · 2000W–3000W for thicker, heavier duty. Not sure? Read how to choose laser welder power.
