Check Whether Your Fiber Laser Can Use Mixed Gas Cutting

What We Need to Confirm

• Laser brand, model, and power level from 3kW to 60kW.
• Main material: carbon steel, stainless steel, aluminum, or mixed production.
• Typical thickness range and the thickness that causes the most production pressure.
• Current assist gas method: oxygen, nitrogen, compressed air, or an existing mixed gas setup.
• Available liquid nitrogen and oxygen supply, pressure range, and connection conditions.
• Main problem to solve: burrs, slow cutting speed, high nitrogen cost, unstable quality, or limited shift output.

Best-Fit Applications

The strongest fit is usually an end-user shop cutting carbon steel on medium to high power fiber lasers where oxygen is slow, nitrogen is costly, and air cutting quality is not acceptable.

• Factories that need cleaner carbon steel edges with less secondary deburring.
• Laser cutting shops trying to increase output without adding another machine.
• Plants with repeatable thickness ranges and stable gas supply conditions.
• Users who can evaluate results through test cuts and production data, not only catalog specifications.

When We Should Be Careful

Mixed gas may not be the first recommendation if the production problem is unrelated to assist gas, if the gas supply is unstable, or if the job mix is too irregular to measure ROI clearly.
