20L Nitrogen for Plasma Cutting
- 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

FAQs
As a trusted supplier of gas, we frequently get asked questions about gas safety, the difference between butane and propane, as well as the best uses for our gas products. In this blog, we’ll be answering our most common FAQs.
You can place orders online through the Adams Gas shop, by contacting the team by phone or email, or by locating a nearby stockist via their stockist finder. For refills, Adams Gas offers a professional gas cylinder filling service, including collection and re-delivery of customer-owned bottles where required.
Adams Gas supplies a wide range of bottled gases across the UK, including propane, butane, CO₂ (carbon dioxide), helium, argon, nitrogen and welding gases such as MIG and TIG mixtures. They also offer additional services like gas cylinder filling, new cylinders, cylinder testing, third-party storage and transport of dangerous goods.
Yes, nitrogen is widely used for pressure testing and purging because it is inert and does not introduce moisture or oxygen into systems. This makes it suitable for testing pipework, HVAC systems, and other sealed environments. Adams Gas supplies nitrogen bottles commonly used for these professional applications.
Disposable gas cylinders are most practical for short duration tasks, site work, mobile jobs, or low volume usage where portability and convenience are priorities. They are commonly chosen when returning or storing refillable cylinders is not efficient. Adams Gas supplies disposable gas cylinders suited to these use cases.
Disposable gas cylinders are typically used for light welding, brazing, soldering, heating, and maintenance tasks. They are often ed for repair work, installation jobs, and situations where compact equipment is required. Adams Gas provides disposable gas cylinders suitable for professional and trade applications.
Disposable cylinders offer convenience and portability, while refillable cylinders are generally more cost effective for regular or high volume use. Disposable options are best suited to occasional or mobile work where efficiency and ease of use outweigh long term running costs. Adams Gas offers both disposable and refillable options so users can choose the most efficient solution.
Nitrogen bottles are commonly ed for applications that require an inert, dry, and stable gas supply. These include pressure testing, purging, leak detection support, tyre inflation, laboratory use, and certain industrial processes. Adams Gas supplies nitrogen bottles suitable for professional and trade applications where consistency and reliability are essential.
Choosing the correct nitrogen bottle size depends on usage volume, flow requirements, and whether mobility or reduced changeovers is the priority. Smaller bottles suit site work and intermittent use, while larger cylinders are more efficient for workshops and continuous applications. Adams Gas offers nitrogen bottles in multiple sizes to support different working environments.
