Plasma cutting is the fastest cutting process. Plasma cutters can cut most types of metal and thicknesses depending on the machine that is used across a wide variety of applications. These work by sending an arc of electric current through a high-speed stream of inert gas usually compressed air. Plasma cutters use voltage to heat compressed air and create a plasma arc. Cutters will cut conducting metals including steel, stainless steel, aluminium, copper and brass.
Are you in the market for a plasma-cutting machine? Well, you might need to think about the following features that could create a great investment rather than a machine that doesn't cut.
What material is been cut?
This is important due to the thickness of metal that a plasma cutter can cut. Ensure your plasma cutter can cut the materials you need it to. At Truflame we have a wide range of plasma cutters with different cutting capacities to suit your needs including a new range of Thermacut plasma cutters. The output of the machine is also important to ensure cut capacity, cut quality and sturdiness of a plasma cutter as of course cuts are all that matter for a plasma cutter machine.
How you want to use your cutter greatly impacts which model would better suit your use. Longer use throughout the day, as well as longer slow cutting, means selecting a higher-duty cycle would be able to handle continuous cutting without overheating. Cutting speed as IPM (inches per minute) often determines what they need.
Power Requirements: Plasma cutters have specific power requirements including voltage, amperage, and phase ratings for your outlets. Smaller models commonly use 120 or 240 volts on a single-phase power system, while larger models operate on 3 phase power and may require a breaker rated for 40 amps.
Duty Cycle: Look at the duty cycle (percentage of time the plasma cutter can operate within a 10-minute cycle). A higher duty cycle is better for extended cutting. For example, the Duty cycle indicates the proportion of time a machine can run without overheating within a set duration. For instance, in a 10-minute cycle, a 60% duty cycle allows the machine to run smoothly for 6 minutes, which is 60% of the total time. Factors such as output power and material thickness impact this operational duration. Machines with a duty cycle below 100% need intermittent breaks within 10 minutes, essential for plasma cutters and other electrical tools to prevent overheating.
Portability: Consider the weight, size, and portability of the plasma cutter, especially if you plan to move it around job sites. Smaller, more compact models are easier to manoeuvre. Larger and heavier plasma cutters, while powerful, are typically less convenient to move around and are better suited for stationary or more industrial applications where mobility isn’t a primary concern.
Selecting the right plasma cutter is essential for achieving clean, precise, and efficient cuts across a wide range of materials. At Truflame Welding Equipment, we understand that every welder's needs are unique, which is why it's important to consider factors like material thickness, power requirements, cutting speed, and portability when making your decision on the best plasma cutter. Whether you're a DIY enthusiast or a professional fabricator, investing in a high-quality plasma cutter will not only enhance your productivity but also save you time and money in the long run. With the right knowledge and tools, you'll be equipped to tackle any cutting project with confidence.
