What to look for when buying a cheap plasma cutter

There are some important features you need to look for in whichever unit you decide to buy. This is to ensure that it serves the purpose you have in mind. The things to consider include the following;

Duty Cycle

The duty cycle of a plasma cutter is a very important factor to consider when you are to get one. There are plasma cutters designed for shorter durations. You can make your buying decision based on the average thickness the unit is capable of cutting if you need a unit that can work all day under a heavy load. Though for the shorter durations duty cycle tend to maximize the amount of power available during that time but may not perform the same under significant or heavy usage.

Input Voltage and Amperage

The input voltage of the unit is another important feature you must consider. The common plasma cutters are either 120 or 220 volts. Though there are some units that are capable of working with either. Therefore, depending on which volt you have available in your shop, if there is a 220v outlet available in your shop then your best bet is to go that route.

Cutting Speed and Thickness

Another important variable is the cutting speed and thickness of the plasma cutter. This actually depends on the length of the cuts you need to make. When you get to the maximum thickness rating of the plasma cutter, it becomes slower at cutting. When you have to slow down you’ll often have to go back and clean up the cut. Hence, you need to understand what types of materials you will be cutting most times then make sure the unit you choose can comfortably and quickly handle it.

Start Method

We have two types: high frequency and contact, this is also an important feature to consider. You need s contact start if you will be using a cutting machine near computers, analytical equipment or other sensitive electronic devices. It will ensure that no interference occurs with your other devices.

Type of Air Supply

Different methods are available which depends on what you are cutting if you will need portability or not but forced air is important in plasma cutting. You can also get some units with a built-in air compressor, but most lower-priced units will require a separate air compressor.

How Much Reliable Are The Cheapest Plasma Cutters?

The fact is that you cannot expect to get extraordinary features from the inexpensive plasma cutter. Nonetheless, they are very much reliable to meet your needs for your DIY jobs. Many people have owned these low-cost plasma cutters for years and it is still performing their cutting job without any problem.
