How to Buy the Best Inexpensive Plasma Cutter

5 Tips to Help You Find the Right One

During our testing, we’ve found that some inexpensive plasma cutter can perform better than several pricey options.

And the top cheap plasma cutters available today have already been listed out for you. But how to find the one that will be the right fit for your needs?

Well, we’re going to represent here some simple but useful tips. These will help you select the cheapest plasma cutter and get more bang for your buck!

Tips 1: Keep Your Amps Low

The plasma cutters with higher amps typically come with a high price tag. Choosing a model with low amps is a simple way to narrow your search down of the best budget plasma cutter.

So, what does the amps associated with a plasma cutter actually refer to?

Well, the number of amp basically means the amount of power that it can pierce producing the plasma arc, with higher rating associating to better performance under more demanding conditions.

Hence, by limiting your range to those with lower amp output, you can focus on more affordable unit.

Plasma cutter featuring 30-amp is an affordable option to start. This amp is sufficient enough to work on a good variety of metals with a good range of thickness.

So, you won’t need to sacrifice much useful functionalities to lower the price point.

Tips 2: Look for a model with a lower duty cycle

The duty cycle of a plasma cutter refers to the period that means how many times you can operate the torch continuously within 10 minutes without causing the system to overheat.

Plasma cutter with high duty cycles is perfect for longer periods of use, which is essential to meet product quotas or speed.

Plasma cutters with high duty cycles tend to come with higher price-tag. So, if speed is not a priority for your project, it’s wise to opt for a model with a lower duty cycle. 

40% duty cycle of a plasma cutter is adequate to offer a reasonable amount of productivity for home use.

Tips 3: Aim for lower thresholds

The severance and cut thickness- these two values refer to the maximum thickness of a metal that you can cut through. For clean and smooth lines, you should focus on cut thickness.

You can consider these two factors for lower values to enhance your savings.

First, take into consideration the thickness you need to cut for your project most frequently. Then, choose a model with a maximum as close to it as possible.

As the higher value of these two factors means more powerful and more expensive plasma cutter, you don’t need to go over that maximum value.

Tips 4: Look for the accessories that come with the unit

Many plasma cutting machines come with additional components and various accessories. Before choosing a model, pay attention to what the unit includes, such as connections, filters, regulators, etc. and consumable.

List these items- non-essential components for your work, which can quickly translate into some significant savings. You don’t need to get many consumable with the base model as you can buy additional for continued use.

Tips 5: Focus on feature and your need more than just the price tag

You can find some models that are inexpensive but will give you better performance.

Focus on all the basic features and aspects of the units instead of only on their price tags and compare the models to choose the right unit that will actually give you the best bang for your buck.

Additional Information

The plasma cutting or plasma arc cutting is a melting/ cutting process of electrically conductive metals. This process involves the use of a jet of ionized gas (plasma) at temperatures above 20,000°C.

During the process, an electric arc is struck between the anode (workpiece) and the cathode (an electrode). The electrode is suspended in air- or water-cooled gas nozzle which compresses the arc causing the high temperature, narrow and high-velocity plasma jet to form.

This process is useful to cut copper, brass, aluminum, steel, stainless steel, and other conductive metals.

Plasma cutting is an alternative to the oxy-fuel cutting process.

Plasma cutting differs from the Oxy-Acetylene or oxy-fuel process in that in the plasma cutting process, an electric arc is used to melt the metal. 

On the other hand, in the oxy-fuel process, Oxygen and fuel are used to create a reaction with the workpiece where the Oxygen oxidizes the mOxygental.

 The produced heat from the exothermic reaction helps to melt the metal.

So, which process is the winner?

It entirely depends on what you need.

If your project needs the ability to work on any metal and clean, precise cut, then a plasma cutter is undoubtedly the best option.

On the other hand, if your work requires you to cut through 20-inch metal, go for the oxy-acetylene process.

And what about the price or cost?

Well, cost or price also depends on what you’ll do with the unit.

Initially, a plasma cutter tends to be expensive.

To learn more about plasma cutter price, read our article here.

There are five different components that comprise the torch consumables for a manual plasma cutting system. These are:

• Nozzle- It aims the plasma arc. It helps to funnel gas flow, which also helps to constrict and shape the arc.
• The shield- It protects the rest of the consumables
• Retaining cap- It covers and holds the consumable stackup together
• Swirl ring- It channels the gas in a couple of different directions as it comes from the machine and down the torch.
• Electrode- It helps to carry the current from the plasma torch to the plate.

The most important protective gears that you need for plasma cutting is face shields and eye protection. These PPEs will save your eyes and injuries from flying dust and debris.

Don’t forget to wear sturdy leather gloves to shield your from burns caused by debris and sparks.

Some high-end plasma cutting units come with a set of basic gloves and goggles. But remember that goggles won’t protect your entire face. Additionally, the gloves are also prone to wear out after some uses.

So, it’s wise to purchase additional safety gear for use while working with a plasma cutter.

9 FAQs

(Frequently Asked Questions) 

About Plasma Cutter

 1. Who invented the plasma cutter?

In the mid- 1950s, the plasma cutting process was invented. The patented holder found that when a high- velocity jet of super-heated gas was sent through a constricted opening, an ionized plasma is produced that can melt metal. High-precision plasma cutter became available in the late 1980s into the 1990s. The Invention of CNC plasma cutters has brought great flexibility in cutting diverse shapes.

  2. What metals can a plasma cutter cut?

Plasma cutter is an ideal tool for cutting conductive materials such as stainless steel, mild steel and aluminum. But plasma cutter is also used for alloys and other types of metals- brass, copper, cast iron, titanium are some examples

  3. How thick or thin metals can a plasma cutter cut through?

A plasma cutter can efficiently cut both thick and thin materials. In general, plasma cutter with a hand-held torch can cut up to 1.5- inch (38 mm) thick steel plate. On the other hand, the CNC plasma cutter can cut steel up to 6-inch (150 mm) thick.

4. How many amps does a plasma cutting machine draw?

40 amps plasma machine of most brands works out well for cutting 3/8-inch thickness. 50 amps is perfect for ½- inch cut. Remember, it’s not the maximum thickness of cut that a plasma cutting unit can cut. But, it’s a good rule to follow for achieving excellent cutting quality and speed.

  5. Is a plasma cutter efficient to cut thick metal?
