  • High‑purity nitrogen for smoother, cleaner plasma cuts
  • 20L capacity for extended operation and fewer changeovers
  • Stable pressure output supporting consistent arc performance
  • Reduces oxidation on sensitive metals and improves edge quality
  • Non‑flammable, inert gas for safe workshop use
  • Compatible with most plasma cutting systems using nitrogen as a primary or secondary gas
  • Reliable performance for light‑to‑medium industrial workloads

Nitrogen is commonly used in plasma cutting as a primary cutting gas or shield gas, depending on the torch and material. It helps maintain a stable arc, reduces oxidation and improves cut quality on a variety of metals.

Typical applications include:

  • General fabrication and sheet‑metal work
  • Automotive repair, brackets and custom parts
  • Agricultural and machinery components
  • HVAC ducting and installation work
  • Mobile engineering and on‑site cutting
  • Prototyping and small‑batch manufacturing

Metal Performance Notes
Stainless Steel Smooth, clean edges with reduced oxidation
Mild Steel Stable arc performance on thin‑to‑medium gauges
Aluminium Good for thin sections; helps reduce porosity and roughness
Galvanised Steel Minimises burn‑back and helps preserve coating
Copper & Brass Suitable for thin materials with correct torch settings
