Can a Plasma Cutter Run with a Small Compressor? ft. Vevor CUT50P

Introduction

In this article, we’ll explore the capabilities of the Vevor CUT50P plasma cutter when paired with a small 3-gallon air compressor. The experiment will cover both a small compressor and a larger model, analyzing the performance and effectiveness of the plasma cutter across various voltages and materials.

Experiment Overview

The journey starts with acquiring a larger compressor from Harbor Freight. This unit comes with a robust 5.1 CFM rating, a 27-gallon tank, and can achieve a maximum pressure of 200 PSI. Given its specifications, this big compressor is expected to provide sufficient power to run the Vevor plasma cutter seamlessly.

Once the larger compressor is ready, we’ll set up the Vevor CUT50P plasma cutter. This model is a 50-amp non-touch plasma cutter, allowing users to initiate the arc without direct contact with the material. After an initial setup that involved a few fittings adjustments, we connected the plasma cutter to the small 3-gallon air compressor to see how it performs.

Performance Analysis

Small Air Compressor Testing

Setting Up: The initial settings required the small compressor to be set at around 65-70 PSI, while the plasma cutter’s regulator was fine-tuned to approximately 6-7 MPa. With these settings in place, the small compressor successfully managed to operate the plasma cutter without any immediate issues.
Cutting Session: During a cutting session using 1/4 inch mild steel, we found that the small compressor held up well. The plasma cutter was engaged for 5 to 7 minutes without any trouble, with only minor fluctuations toward the end of the operation. Interestingly, the compressor maintained adequate pressure throughout the cutting, showcasing its ability to handle continuous operation.

Transition to 240 Volts

Switching to 240 volts, the plasma cutter delivered better performance. However, cutting through half-inch steel proved challenging when operating at 120 volts due to lower amperage, requiring slower cuts and additional time. This reaffirms the notion that for thicker material, the plasma cutter's optimal performance is achieved at 240 volts.

Final Cut Tests

While primarily designed for metallic materials, we put the Vevor CUT50P to the test on various unusual objects. The plasma cutter managed to slice through items like rusty metals, a Coke can, and surprisingly, even thin plywood. However, the results varied when it came to soft or non-metallic materials, indicating plasma cutters' limitations with such items.

Conclusion

Through this experiment, it is evident that the Vevor CUT50P plasma cutter can effectively run on a small air compressor for light to medium material cutting. While a larger compressor provides more robust performance, the small compressor stands up well for specific applications, making it a viable option for users with limited space or budget.
