Our nitrogen oxygen mixing device uses микрокислородная технология лазерной резки to produce a precisely calibrated N₂/O₂ mixed gas — eliminating burrs on carbon steel while delivering 3× faster cutting speed than traditional oxygen cutting. Designed for high power laser machines from 3kW to 60kW.
Raw materials stored in tanks, pressure 20–25 bar
Converts liquid gases to gaseous form
Stable pressure + proportional mixing → N₂ 95% / O₂ 5%
Output: 12–16 bar, flow rate up to 200m³/h
Input: N₂ + O₂ at 20–25 bar. Output: N₂ purity ~95%, pressure 12–16 bar, max flow 200m³/h. Compact gas tank (capacity >3m³).
800mm × 350mm × 1100mm, weight 90kg. One device supports up to three laser machines simultaneously (One-to-Three configuration).
High cutting speed + zero burrs. After installation, adjust ratio between N₂ 95% and O₂ 5% for different board thicknesses. Built-in program analyzes usage ratio and records gas purity requirements.
Works with all major brands: HAN'S, DNE, PENTA, LEAD, HSG, and more. Compatible with BODOR, JIATAI, HG LASER, XUNLEI, and other global brands.
Burr-free edges, 3× faster cutting speed, and near-zero electricity cost. Our maintenance-free gas supply system is compatible with Han.s laser, DNE, PENTA, LEAD, HSG, BODOR and other major brands.
Increase laser cutting speed up to 3× compared to oxygen cutting. Example: 8mm carbon steel at 16m/min with mixed gas vs only 2–3m/min with O₂.
Unlike nitrogen cutting which produces burrs on plates ≥8mm (3kW) or ≥10mm (20kW), mixed gas cutting produces clean, burr-free surfaces on carbon steel — no secondary grinding needed.
Only 2 kWh per 24 hours — near-zero electricity cost. The device has no moving parts and requires no maintenance. Compare this to air compressors that draw 15–30 kW continuously and need regular filter/oil changes.
Power consumption: only 2 kWh / 24 hours. Unlike air compressors requiring filter/oil changes every 3,000 hours, our industrial laser gas equipment is maintenance-free.
The only manufacturer with stable one-to-three mixed gas equipment. One industrial gas mixing station powers up to three laser machines of different power levels simultaneously.
Air compressors risk oil/water contamination burning laser head lenses ($5,000–$50,000 loss). Our pure liquid gas source keeps your optical system 100% safe.

A mixed gas device precisely blends liquid nitrogen (N₂) and liquid oxygen (O₂) into a calibrated N₂/O₂ gas mixture (typically 95%/5%). This micro-oxygen mixture is used as the auxiliary gas in high-power laser cutting, delivering 3× faster cutting speed on carbon steel compared to pure oxygen, while eliminating burrs entirely.
Yes. The LISHI LASER Устройство смешанного газа works with all major laser brands including HAN'S, DNE, PENTA, LEAD, HSG, BODOR, JIATAI, HG LASER, and XUNLEI. It supports machines from 3kW to 60kW. If your machine uses standard auxiliary gas connections, it is compatible.
Cutting range depends on laser power: 3kW handles up to 16mm carbon steel, 20kW up to 25mm, 30kW up to 30mm, and 60kW up to 40mm. It also cuts stainless steel and aluminum with excellent results.
The mixed gas device is designed for speed and cut quality — not gas savings. It consumes only 2 kWh per 24 hours (near-zero electricity cost). The primary value is 3× faster cutting and burr-free edges, which eliminate manual deburring labor. Gas costs may be similar or higher than pure N₂, but the throughput and quality gains far outweigh the difference for professional shops.
No. Unlike air compressors that need filter/oil changes every 500–3,000 hours, the LISHI Устройство смешанного газа is maintenance-free. It uses pure liquid gas sources with no moving parts that wear out. Power consumption is just 2 kWh/24h.
Yes. LISHI LASER is the only manufacturer offering a stable One-to-Three configuration. One mixing station can simultaneously supply up to three laser machines of different power levels (e.g., one 3kW and one 20kW).
Air cutting produces oxidized, rough edges and risks oil/water contamination that can burn expensive laser head lenses ($5,000–$50,000). Mixed gas delivers smooth, burr-free, silver-white cut surfaces with zero contamination risk — and cutting speeds 30% faster than air.
Installation is straightforward and typically completed within one day. The device connects to your existing liquid gas supply and laser machine. We provide detailed installation guides and remote technical support for all customers.
