A Guide to Choosing the Right Plasma Cutter

Choosing the best plasma cutter can be challenging if you've never used one before. However, they can help you achieve better results and work more efficiently on assignments.

Here at ArcCaptain, we've broken down all the information you need to choose the best plasma cutter into a guide that includes several important considerations.

Types of Materials Suitable for Plasma Cutting

When considering the use of a plasma cutter, it's essential to understand the type of material you intend to cut and its thickness. Plasma cutters are versatile tools capable of slicing through a variety of materials, provided they conduct electricity. This includes a range of metals, each with its unique properties and applications.

  1. Steel: A common material in construction and manufacturing, steel can be effectively cut with a plasma cutter. It's used in building structures, automotive components, and machinery.

  2. Stainless Steel: Known for its resistance to corrosion and staining, stainless steel is often used in kitchenware, medical instruments, and architectural elements. Plasma cutters can neatly slice through this material.

  3. Copper: Widely used in electrical wiring and plumbing due to its excellent conductivity and malleability. Plasma cutting is a suitable method for shaping and cutting copper for various applications.

  4. Aluminum: Lightweight yet strong, aluminum is used in a variety of applications from aircraft manufacturing to kitchen utensils. A plasma cutter can easily handle aluminum, making it ideal for both industrial and domestic projects.

  5. Brass: An alloy of copper and zinc, brass is commonly used in decorative items, musical instruments, and fittings. Plasma cutting can be an effective method for working with brass, especially in custom and decorative work.

It's important to note that the thickness of the material will also dictate the capability of the plasma cutter needed. Different models of plasma cutters have varying power levels, designed to handle materials of different thicknesses. Understanding these specifications is crucial for achieving precise and efficient cuts.

Plasma Cutting Output Considerations

You should consider the potential output of each potential plasma cutter you are considering. This can be achieved by comparing the cutting speed to the thickness of the material to ascertain the efficiency and speed of a particular cutter. On some machines, this data is shown as Inches Per Minute, or IMP.

This will assist you in estimating the amount of productivity you can achieve with that option and how soon a cutter can finish the task at hand.

ArcCaptain Plasma Cutter Buying Guide

Amperage Output And Maximum Cutting Thickness

When choosing a plasma cutter, it's crucial to consider the amperage output and maximum cutting thickness. Higher amperage provides a higher clean cut thickness, allowing for faster cutting. ArcCaptain offers a range of amperage options to suit different cutting needs.

Input Voltage

Considering the input voltage is essential, especially if you plan to use the plasma cutter on-site where 220V may not be available. ArcCaptain's plasma cutters provide dual voltage input, offering versatility for various working environments.

Duty Cycle

The duty cycle indicates how long the plasma cutter can continuously cut at a rated amperage output. ArcCaptain's plasma cutters are designed with exceptional duty cycle ratings, ensuring uninterrupted cutting for longer periods.

High-Frequency Start Or Blowback Start?

ArcCaptain's plasma cutters offer both high-frequency start and blowback start options. High-frequency start provides a rapid and efficient arc initiation, while blowback start is safer for sensitive electronics and devices.

Frequently Asked Questions

What to Consider When Selecting a Portable Plasma Cutter?

When selecting a portable plasma cutter, there are several factors to consider. First, you need to determine the thickness of the material you will be cutting. This will help you choose the right power output for your plasma cutter. You also need to consider the duty cycle, cutting speed, and portability of the plasma cutter. Additionally, you should look for a plasma cutter that is easy to use and maintain.

How Does a Built-in Air Compressor Benefit a Plasma Cutter?

A built-in air compressor is a valuable feature in a plasma cutter because it eliminates the need for an external air compressor. This makes the plasma cutter more portable and easier to use. With a built-in air compressor, you can start cutting right away without having to worry about connecting an external air compressor.
