To cut 12 mm mild steel cleanly, you typically need around 3 kW. Here is the full wattage-to-thickness master table across six materials, plus the three buying mistakes most first-time fiber laser owners make.

For most metal shops, fiber wins on speed, electricity, and maintenance — but CO2 still owns acrylic and wood. Head-to-head over 5-year TCO + when a fiber+CO2 hybrid pays back faster.

If you&#82…

A practical guide to choosing a handheld fiber laser welding machine by power, cooling, source, controls, safety, supplier support, and cost.

Compare air-cooled and water-cooled laser welding machines by power, portability, duty cycle, maintenance, cost, and ideal applications.

Handheld welders shine for repair, low-volume, and access-constrained work. Robotic cells dominate production. Here is the framework to pick the right one for your throughput and skill mix.

How many watts you actually need depends on material thickness, edge quality goals, and throughput — not the marketing brochure. A practical buyer guide for sign shops and makers.

The laser source is half the machine. Compare lifespan, warranty terms, beam quality (M²), after-sales support — and learn which source brands are worth the premium for which use cases.

A 6 kW fiber typically pays back in 14-22 months for a single-shift shop. TCO breakdown, payback table at four utilization levels, and 30+ vendor questions.
