Assist Gas Flow Calculator
Calculate gas consumption rates and monthly operating costs for laser cutting operations
Cutting Parameters
Most common for stainless steel and aluminum
Flow Rate
20.92 m³/hour
Gas Consumption
Based on standard 50L cylinder at 200 bar (≈10m³ usable gas)
Cost Analysis
Gas price: $0.25/m³ (regional pricing may vary)
Gas Selection Guide
Best for stainless steel, aluminum. Prevents oxidation. Pressure: 12-20 bar.
Optimal for carbon steel. Exothermic reaction increases cut speed. Pressure: 0.3-2 bar.
Budget option for mild steel. Some edge oxidation. Pressure: 8-12 bar.
Titanium and reactive metals. Premium cost justified for critical applications.
Cost Optimization Tips
• Minimize pressure: Use lowest pressure that maintains cut quality (saves 10-20%)
• Optimize pierce time: Excessive pierce delay wastes gas
• Check for leaks: Even small leaks cost $500-2000/year
• Consider bulk supply: Liquid nitrogen tanks reduce costs by 30-50% vs cylinders
• Nozzle maintenance: Worn nozzles require higher pressure, increasing consumption
Note: Flow rate calculations are approximations based on nozzle diameter and pressure. Actual consumption varies with nozzle design, gas temperature, line pressure losses, and cutting duty cycle. Gas prices shown are typical industrial rates and vary by region, supplier, and contract terms. For precise measurements, install a flow meter on your gas supply line.
