Buying Guide
Air Compressor Buying Guide for Plasma Cutting
Choosing the right air compressor is crucial for your plasma cutters performance. Heres what to consider:
CFM Rating
CFM (cubic feet per minute) is the most critical factor. Your plasma cutter will specify its CFM requirement at a certain PSI (pounds per square inch). Ensure your compressor delivers AT LEAST this CFM at the required PSI. For example, a cutter requiring 6 CFM at 90 PSI needs a compressor that can provide that level of airflow.
Tank Size
A larger tank allows for longer cutting times before the compressor needs to cycle on. This reduces wear and tear and maintains more consistent air pressure. Consider the tank size based on your typical cutting duration; a 20-gallon tank is good for light-duty, while a 60-gallon tank suits more frequent or longer cuts.
PSI Capability
Verify that the compressor can reach the PSI specified by your plasma cutter. Most plasma cutters operate around 60-90 PSI. You also want to make sure the compressor includes a regulator to control output PSI.
Frequently Asked Questions
What size air compressor do I need for my plasma cutter?
The required air compressor size depends on your plasma cutters specifications, usually measured in CFM (cubic feet per minute) at a specific PSI (pounds per square inch). Check your plasma cutters manual for its CFM and PSI requirements to select a compressor that meets or exceeds those values to ensure optimal cutting performance.
What PSI and CFM should I set my air compressor for plasma cutting?
Always refer to your plasma cutters manual for the recommended PSI and CFM settings. These settings are crucial for achieving clean and efficient cuts. Using the incorrect settings can lead to poor cut quality, premature wear on consumables, and potential damage to the plasma cutter.
Do I need an air dryer and filter for my plasma cutter?
Yes, an air dryer and filter are highly recommended. Moisture and contaminants in the air can severely impact cut quality and damage your plasma cutter. An air dryer removes moisture, and a filter removes particles, ensuring clean, dry air reaches your plasma cutter.
What is the difference between a single-stage and two-stage air compressor for plasma cutting?
Two-stage air compressors generally deliver higher CFM at higher PSI compared to single-stage compressors. This makes them better suited for plasma cutters that require a lot of air. They also run cooler, leading to longer lifespans, especially with frequent use.
How often should I drain the water from my air compressor tank when plasma cutting?
You should drain the water from your air compressor tank frequently, especially during periods of high humidity. Drain the tank after each use, or at least daily, to prevent moisture from entering your plasma cutter. This helps protect the internal components and maintains the quality of your cuts.
Final Thoughts
In conclusion, choosing the right air compressor for your plasma cutter depends heavily on your specific requirements. We examined several models, highlighting their strengths in terms of air delivery, tank size, and portability.
The compact and lightweight model is ideal for smaller projects and occasional use. Conversely, a larger compressor with a substantial tank is better suited for continuous, heavy-duty cutting. Consider the amperage of your plasma cutter, the materials youll be working with like steel or aluminum, and your workspace limitations.
Ultimately, select the air compressor that best balances power, capacity, and your budget. Take the plunge and get your air compressor today!
