300W Metal and Nonmetal Laser Cutting Machine for Sale

What "Mixed Laser" Actually Means

The STJ1325M is a hybrid CO2 laser cutter, not a fiber machine. The 300W beam-combined laser tube (Yongli or RECI) merges output from two CO2 sources into one optical path, giving enough peak power for thin sheet metal while keeping the long wavelength suited to acrylic, MDF, and plywood.

Because the CO2 wavelength (10.6 μm) is partially reflected by polished metals, the practical metal limit is roughly 2mm stainless and 3–4mm carbon steel with assist gas. For thicker metal, the broader hybrid laser cutting system category lists higher-power options, while pure metal jobs are better matched by a dedicated fiber laser cutting machine.

Mixed vs. Fiber vs. CO2: Which Buyer Is This For?

The mixed laser sits between two specialist categories. Buyers cutting only metal will get more capacity from a dedicated metal laser cutting machine, while pure non-metal shops are better served by a standard CO2 cutter.

Operating Costs and Consumables

The 300W beam-combined CO2 tube has a typical service life around 10,000 hours, after which it can be replaced from the CNC laser parts and accessories catalog. Mirrors and focal lenses need cleaning every few weeks and replacement every 6–18 months. Oxygen for metal and compressed air for acrylic are the two main running costs alongside electricity and chiller water.

Practical Applications Beyond the Materials List

✓ Sign and advertising shops cutting stainless letterforms with acrylic backers

✓ Architectural decor producers making mixed-material wall panels and screens

✓ Prototyping studios cycling between thin sheet metal brackets and acrylic enclosures

FAQ

What is the maximum metal thickness this 300W mixed laser can actually cut?

The STJ1325M reliably handles stainless steel up to 2mm, and carbon steel up to 3–4mm with oxygen assist gas. Pushing beyond those limits produces dross, slow speeds, and inconsistent edges. For sheet metal above 4mm, a fiber laser is the correct choice.

Can this machine replace a separate CO2 cutter and a fiber cutter?

Only for shops working with thin sheet metal alongside nonmetals. Mixed lasers excel at sub-2mm metal plus full-thickness acrylic, wood, and MDF, but cannot replace a fiber laser for production sheet metal fabrication or a high-power CO2 for thick acrylic-only volume work.

What software runs the included RD6332M control system?

The RD6332M ships with RDWorks as standard control software and is also compatible with LightBurn, which most operators upgrade to for better workflow and design import. File formats accepted include BMP, JPEG, GIF, TIFF, PCS, TGA, and HPGL plot files.

How long does the 300W beam-combined laser tube last?

Yongli and RECI 300W CO2 tubes are rated for around 10,000 hours under normal duty cycles. Maintaining chiller water between 18 and 25 degrees Celsius and avoiding sustained 100% power runs significantly extends actual service life.

Why does the cutting chart specify oxygen for metal but air for acrylic?

Oxygen reacts exothermically with steel during cutting, adding energy and producing cleaner edges on stainless and carbon steel. Air assist on acrylic prevents flame-up and keeps the edge optically clear. Using the wrong gas damages cut quality and can scorch nonmetals.
