Which Fiber Laser Should You Buy?

The SP404 is a compact 4x4 ft single-pallet laser offering big-shop cutting power in a small footprint. The SP510 steps up to a 5x10 ft pallet for full sheet processing. The Flex Series spans 5'x10' to 8'x20' beds with power up to 20kW for high-volume, large-format cutting operations.

Piranha offers 3kW and 6kW options on the SP404 and SP510, and 3kW, 6kW, 12kW, or 20kW on the Flex Series. Higher kW ratings cut thicker plate faster; if you regularly process heavy-gauge steel or plate, a 12kW or 20kW Flex Series machine will deliver better throughput than a 3kW unit.

Yes. All Piranha fiber lasers are engineered with an automation-ready design for material loading and unloading, whether you need it now or plan to add it later. This lets shops scale production without replacing the machine, protecting your capital investment as demand grows.

Starting prices vary by model and power: the SP404 begins at $134,900 (3kW) or $159,900 (6kW), the SP510 starts at $173,900 (3kW) or $195,900 (6kW), and the Flex Series starts at $282,000. Use Piranha's 'Build and Price Your Perfect Shop' tool for a configuration-specific quote.

Piranha provides U.S.-based technical support, installation services, and user training, plus real-world application and cutting advice from fabrication experts. Support is domestic, so you speak directly with knowledgeable staff rather than navigating overseas support queues, and same-day parts shipping is available from Belvidere, IL.

Plasma cutters are typically better suited for cutting super-thick materials at lower cost per machine, while fiber lasers deliver superior cut quality, speed, and precision on thinner-to-mid-gauge metals. Piranha's engineers can assess your material thickness, production volume, and budget to recommend the right thermal cutting technology.
