Buying Guide
Plasma Cutter Gas Buying Guide
Choosing the right gas for your plasma cutter is crucial for optimal cutting performance and quality. Several factors should influence your purchase decision.
Gas Type
The most common gases used are compressed air, argon, and nitrogen. Compressed air is the most versatile and economical choice for general-purpose cutting of mild steel and other common metals. Argon is often preferred for cutting non-ferrous metals like aluminum and stainless steel, while nitrogen is often used with stainless steel for cleaner cuts.
Purity Levels
Ensure the gas you purchase has the appropriate purity level. Impurities can negatively impact the cut quality and may damage your plasma cutter. For most applications, industrial-grade gases will suffice, but consult your plasma cutters manual for specific purity recommendations.
Cylinder Size and Pressure
Consider your cutting frequency and the size of your projects. Larger cylinders contain more gas, extending the time between refills, which reduces downtime. Always check the cylinders pressure rating and ensure it’s compatible with your plasma cutter’s requirements.
Frequently Asked Questions
What type of gas is best for plasma cutting?
The most common and versatile gas for plasma cutting is compressed air. Its readily available, cost-effective, and produces a clean cut on many materials. However, other gases like nitrogen or argon can be used for specific materials and better cut quality.
Can I use a standard air compressor for my plasma cutter?
Yes, but make sure your air compressor can provide sufficient air pressure and CFM (cubic feet per minute) as specified by your plasma cutters requirements. An undersized compressor will lead to poor cut quality and potentially damage the cutter. Consider a dedicated air compressor with a large tank for optimal performance.
How important is the air filter and dryer for plasma cutting?
Extremely important. The air filter removes moisture and contaminants from the compressed air, preventing them from entering the plasma cutter. Using a dryer is especially important to remove the moisture because it will affect the quality of the cut and the life of the consumables.
What happens if I use the wrong gas or gas pressure?
Using the wrong gas can result in a poor-quality cut, increased dross, and accelerated wear on your consumables. Incorrect gas pressure can also damage the torch and negatively impact cut quality. Always consult your plasma cutters manual for recommended gas and pressure settings.
How do I know when my gas is running low?
Most plasma cutters have a built-in pressure gauge that indicates the gas pressure. Regularly monitor this gauge to ensure the pressure is within the specified range. If youre using a gas cylinder, keep an eye on the cylinders pressure gauge to avoid running out of gas mid-cut.
Final Thoughts
In conclusion, choosing the right gas for your plasma cutter significantly impacts cut quality and overall performance. Argon offers clean, precise cuts on thin materials like stainless steel, while nitrogen is an economical option for mild steel, producing good edge quality.
For thicker materials and enhanced cutting speeds, consider a blend of argon and hydrogen. Oxygen-rich gases, though powerful, may cause oxidation that impacts the final result. Consider the metal youll be working with most often and the desired outcome.
Ultimately, the best choice depends on your specific needs and the projects youll be tackling. Explore the options and select the gas that aligns with your cutting requirements for optimal results. Happy cutting!
