Buyers Guide: Important Factors to Consider When Buying

The wide variety of air dryers in the market has made it difficult for interested buyers to identify the right one. In this section, we will be taking you through important factors you need to consider when shopping. 

• Power Input 

Plasma cutters are known to work on AC as the input source of power. A good number can work at either 110V/120V or 110/220V. However, there are times when you might find automatic dual voltage power sources in some plasma cutters. Changing the input power depending on the power requirements will be much easier. 

Before you settle on a particular air dryer, ensure that your place of work has 110V or 220V outlets. You also have to ensure the breakers have sufficient amps that will endure the units’ amperage. 

• Duty Cycle 

Duty cycle is an essential factor that you should never forget to consider when shopping for the air filter. The duty cycle will denote the plasma cutter’s ability to perform under a specific load for some duration of time. 

Air dryers with low duty cycles suggest optimal performance for a specified period. When the duration is over, there are possibilities the performance will degrade taking more time to see off your project.  When dealing with heavy-duty projects, a duty cycle of 50% to 60% will be enough. 

• Consumables 

Standard plasma cutters use up to five different consumables namely: Swirls, Shield, Retaining cap, Nozzle, and electrode.  Shield helps in protecting the consumables from sparks and molten metal.  Retaining cap helps in ensuring the consumables are retained collectively. 

The nozzle will focus on the plasma arc. The size of the nozzle will play an integral role in ensuring the arc is focused. 

• Portability 

There are times when you might want to use the plasma cutter in different locations. It simply means that the mobility of the air dryer will be an important factor.  

You have to consider the weight since it will determine how easy it will be to move the air dryer from one location to another.

• Accessories 

You need to ensure that the dryer you are about to purchase comes with the right accessories that will ensure you are safe when using it and that it works as it should. For example, you will need to ensure it comes with a helmet to help protect your head

There should be a pair of safety gloves to help protect your hands. When such accessories are missing, there are possibilities of you hurting yourself.

1. Do I need an air dryer?

Plasma cutters will be spoiled when oiled, dirty and contaminated air is used. The air dryer helps in filtering the air from dust, dirt, moisture, oil, and other types of contaminants.

2. What is a good air filter?

There are a few different types of dryers that can be used with plasma cutters. Some of the most popular are film-cooled, water-cooled, and oil-cooled. Film-cooled air dryers use a thin layer of aluminum on the inside to help cool the air. Water-cooled dryers use some type of fluid to cool the air before it is released.

3. How long does a dryer keep the plasma cutter tip working?

This entirely depends on consumption hence does not have a fixed period. In case you are not using the air dryer with a plasma cutter, then the tip will have a durability of 2-4 days.
