Plasma Cutting Gas

We supply a full range of plasma cutting gases for industrial fabrication and metalworking. The choice of plasma gas depends on the material being cut and the specification of your plasma machine. Our rent-free cylinders are available in 9.4L, 10L, 20L and 50L sizes with next-day delivery across the UK.

Which Gas Do You Need for Plasma Cutting?

Plasma cutting uses an electrically conductive gas to transfer energy from a power source to the material being cut. The gas you need depends on what you are cutting:

  • Compressed Air — The most versatile and cost-effective option. Suitable for cutting mild steel, stainless steel and aluminium up to 25mm. Ideal for general fabrication work.
  • Nitrogen — Produces cleaner cuts on stainless steel and aluminium with minimal oxidation. The preferred choice when cut quality and edge finish are critical.
  • Oxygen — Best for mild steel and carbon steel. The exothermic reaction increases cutting speed significantly, especially on thicker materials. Produces a smooth, dross-free edge.

Rent-Free Plasma Cutting Gas Cylinders

All our plasma cutting gas cylinders are supplied on a rent-free deposit basis — no ongoing rental charges. Available in sizes from 9.4L up to 50L to suit workshops of all sizes. For high-volume users, ask about our manifold packs.

You should always follow your plasma system manufacturers instructions when selecting gases. For advice, call us on 0800 195 4445.
