PENTA 30kW End User: 16 m/min on 8mm Carbon Steel with Mixed Gas
Verified cutting parameters from an on-site installation in Taiwan — a PENTA 30kW fiber laser producing clean, burr-free cuts across multiple thicknesses.
The Challenge
A precision metal fabrication shop in Taiwan operates a PENTA 30kW fiber laser, cutting carbon steel plates from 8mm to 20mm thickness. Their customers demand welder-ready edges — no oxidation, no grinding, no secondary processing.
- Laser: PENTA 30kW fiber laser
- Material: Carbon steel (8mm–20mm)
- Quality requirement: Zero burrs, weld-ready edges
- Previous gas: Pure oxygen — slow speeds with heavy edge oxidation
The Solution: LISHI Mixed Gas — Single Station
LISHI LASER installed one mixed gas station feeding the PENTA 30kW laser. The system delivers a precise N₂/O₂ blend that enables high-temperature oxidation at the cutting front — combining oxygen's reactivity with nitrogen's cooling and edge protection.
The result: clean silver-white edges that go straight to welding, at speeds 3-5x faster than pure oxygen.
Verified Cutting Parameters
On-site test data from the PENTA 30kW end user in Taiwan. Cuts verified burr-free across all tested thicknesses.
| Thickness | Mixed Gas Speed | Test Location | Result |
|---|---|---|---|
| 8mm | 16 m/min | Taiwan site | Extremely clean cut |
| 10mm | ~12 m/min | Field test | Burr-free |
| 12mm | 9.3 m/min | Taiwan site | No burrs confirmed |
| 16mm | ~8 m/min | Taiwan site | Clean edge |
| 20mm | 5.6 m/min | Taiwan site | PENTA end user — burr-free |
| 25mm | ~3.5 m/min | Field test | Good edge quality |
Key Takeaways
3-5x O₂ Speed
Mixed gas consistently delivers 3-5x the cutting speed of pure oxygen on the same machine. The 30kW laser performs like a much larger system on pure O₂.
Weld-Ready Edges
All thicknesses produced silver-white edges with zero oxidation. Parts go directly from the laser bed to welding — no grinding station needed.
PENTA Compatible
Plug-and-play with PENTA laser systems. No modifications to the laser — connects directly to existing gas inlets. One mixing station can feed two PENTA lasers simultaneously.
