Safety instructions for users

When using a plasma cutter, it is important to observe all safety measures to avoid harming yourself and those nearby. In this section, we are going to discuss safety instructions that you need to observe when using a plasma cutter.

  • Do not allow any unauthorized use to or your plasma cutter without your permission or supervision.
  • Before you start using the machine, warn people who are close that you are about to start working. Ensure that they wear protective gear to such as goggles to protect themselves.
  • Wear the right protective gear before you start cutting. Important protective gear that you need to wear includes goggles (protect your eyes), welding gloves (to protect your hand against burns), welding helmet, the right shoes, and clothing (non-flammable) to protect your body against burns.
  • The plasma cutter process creates a lot of gases and fumes that may harm your health. So, ensure that work in areas where there is proper ventilation. Also, ensure that you wear the right protective mask.

Buyer guide: what to look for when buying

The plasma cutter that you choose will determine the quality of results that you will get. If you want to make your metal cutting tasks, simple, fast, and enjoyable, then you need to purchase a high-quality plasma cutter that will provide the high-quality results that you are looking for. In this section, we are going to give you tips on important factors to consider when buying a plasma cutter for your cutting projects.

Consider power output

One crucial factor that you need to consider when buying a plasma cutter for your cutting projects is the power output. This factor is important because it determines when the machine can cut. For example, a plasma cutter with 12A/120V can only cut metals with 1/8 inch thickness while 60A/240 can slice nearly all metals with 7/8 thickness. Ensure that you buy a plasma cutter with a power output that matches your cutting needs.

Power source

Another crucial factor to consider before buying a plasma cutter is the power source. The standard voltage in most homes is 110/120V. This means that the only plasma cutter that you can use is one with this voltage input. How this voltage input is only ideal for cutting metals with less than 1/2 inch thickness. Therefore, if you want to cut heavier gauge metals, then you need to buy a plasma cutter with 220/240V input capacity. However, because most homes don’t support this voltage then you need to use an inverter to step the voltage.

The gauge of the metal

This is a very crucial factor that most people usually overlook. The gauge of the metal you are planning to cut is a very important factor to consider when purchasing a metal cutter. For instance, If you are planning to cut metal with a thicker gauge, then you need to buy a plasma cutter with higher voltage output (220/240V). The general rule of thumb is that you should never purchase a plasma cutter with the maximum cutting size as the metal you are planning to cut.

Consider the duty cycle

The duty cycle refers to the amount of time the machine can run continuously before cooling off. For instance, a 3 minutes duty cycle means that the machine can run continuously for 3 minutes before it cools off. If you are planning to make long cuts, then it is best if you buy a plasma cutter with long duty cycles. This way, you won’t be forced to take a break while you are in the middle of your cuts.

Consider torch

There are two types of plasma cutting torches. They include a high-frequency torch and contact start torch and they all have their own pros and cons. For instance, the high-frequency torch does not use moving parts meaning that it is stable and dependable. However, the downside of this torch is that it creates electric noise that interferes with electric appliances and also needs frequent maintenance. On the other hand, contact start touch is great because it does not interfere with nearby electrical appliances. Ensure that you choose the right torch that suits your cutting needs.

FAQs about plasma cutter

1.Can a plasma cutter cut aluminum?

Yes, plasma cutting can be performed on any type of conductive metal including aluminum.

2.Can a plasma cutter cut glass?

Glass is not electrically conductive. As a result, it cannot be cut with a plasma cutter. This machine can only cut electrically conductive materials like aluminum, stainless steel, and much more.

3.Can a plasma cutter cut wood?

Much like glass, wood is not electrically conductive and cannot be cut by a plasma cutter.

4.Are plasma cutter touches interchangeable?

Yes, plasma cutter touches are interchangeable. However, you can only interchange with a touch with the same amperage and also have the same starting principle.
