Are these machines capable of cutting like conventional plasma machines? What do they stand out from other machines?

The cutting ability of these cutters is exactly the same as other plasma machines. However, there is a difference in the time cutting between plasma cutters and plasma cutters with built-in air compressors.

 Based on the amount of air that the device can provide, they allow metal cutting only for a certain period of time. Each type of cutter has compressors of different sizes that will give a different cutting time limit. There are many types of machines available today, so you need to check the specifications and note that some machines can maintain cutting pressure that allows non-stop cutting.

Which one is cheaper, A Plasma Cutter, or A Normal Non-Air Compressor machine?

Typically, compressors with built-in compressors will be more expensive than plasma cutters because this type of cutter has built-in air compressors besides plasma. On the other hand, You can also have another option to buy 2 machines with 2 different uses but the price may be the same or even higher.

Moreover, you will find it quite overwhelming and when you have to use it outside, you will find it very inconvenient.

Although the cost of a plasma cutter with built-in air may be higher, They have better quality and convenience. However, don’t  worry because it’s not too much higher than the normal ones

There are many similarities between the Hobart Airforce 27i Plasma Cutter and Hypertherm Hypertherm Super 30. First, they probably have the same specifications but the price of Hobart  Airforce 27i Plasma is a little lower. Its first strength must be mentioned is that it is Compatible with engine-driven welders.

It has Complete cutting capability when powered by an engine-driven welder with a 240 V receptacle of 4 kW or more.  Although this type of plasma cutter has a warranty period of up to five years and is high in quality, its performance is not really high.

A special feature of this product is the ability to cut clean sections up to 3/8 with a capacity to sever 5/8″ at a maximum of 27 amps. Fan-On-Demand – Runs only when needed reducing dust/debris pulled into unit. It has rather more weight and shorter leads, which is incapable of producing sheet metal parts similar to Hypertherm Powermax 30.

Overall the product is quite perfect, there seems to be a little to complain about this plasma cutter. This table can help you find its strengths and weaknesses.

How To Choose The Best Plasma Cutters With Built-In Air Compressors?

Power Source

Most lightweight plasma cutters operate on 120-volt power if they are used in home workshops or around customer houses. A dual input power plasma cutter, running on both 120 and 240 volts, is more adaptable, but it will have a heavier weight than a 120-volt machine.   

If the 240-volt input isn’t required, you should spend the same amount of money on a 120-volt cutter with a better compressor. On a 120-volt household power, you can use a maximum amp of 15. That’ll get you through the steel of up to 3/16 inches. 

Duty Cycle

It’s ideal to have a plasma cutter that can work continuously during the day without being waited to cool down. The duty cycle is positively associated with the amount of time you’ll be able to go with a single continuous cut. 

Although 35% may not seem like much, it equates to nearly 3 minutes of continuous cutting before you need to wait for a plasma cutter to cool down. 


A longer warranty duration demonstrates the manufacturers’ confidence in their cutters’ quality. Regarding plasma cutters, 3 years is a long period. That’s possibly several hours of heating, cooling, and blasting per week. 

The air compressor increases the amount of heat, electricity used, and moving parts in the system. Since the plasma cutters equipped with built-in compressors are more expensive, it may be worthwhile to pay a little more to obtain a machine guaranteed for a longer period. 

You might also think about the extended warranty offered by some manufacturers at an additional expense.   

Advanced Features

Some features can significantly simplify your cutting tasks. Drag cutting technology allows you to initiate the arc and continue the cut by dragging the torch across the metal’s surface. Many torches must be kept at a particular distance higher than the metal without this feature, which might be tough if you’re not physically healthy or getting exhausted after finishing working. 

These days, automatic settings are becoming more widespread. Some cutters lack control settings, detecting and responding to the materials by themselves. Others simply have a single rating and run at max amperage regardless of the metal thickness. 

High-tech power sources, such as inverter tech, can also result in benefits including lightweight. When you are in an inconvenient location, a lighter cutter is easier for you to store, transfer and maneuver.     

Accessibility & Safety

Longer torch leads and power extension cords should be among the most important features that any plasma cutter owner should seek. The majority of torch leads are between 12 and 15 feet long. Anything shorter than that will result in less-than-ideal circumstances. 

A cutter with a simple, user-friendly interface removes lots of guesswork, particularly for beginners. It’s convenient for professionals to have a machine requiring little to no supervision. 

Above all, don’t make a 120-volt cutter accomplish the task of a 240-volt cutter. Things will go wrong. 

Ways To Reduce Dross In Plasma Cutting

When cutting metal with a plasma cutter, the cut’s perimeter will frequently be surrounded by molten metal. Dross refers to the waste and foreign matter accumulating because of the molten metal generated during plasma cuts. 

This excessive hardening of metal is pricey since it causes unprofitable downtime. You undertake post-cut clean-up to remove the dross during these periods of downtime. 

The following are some methods for getting rid of or reducing dross. We divided the solutions into categories based on the different sorts of dross.   

Top Dross

It forms on the plate’s upper edge on both pieces. It could be caused by utilizing worn consumables, such as no longer effective cutting tips. 

Furthermore, cutting a metal piece too quickly can result in top dross. Another reason is that the torch height or standoff is set too high.

How to solve top dross problems:

  • Be sure to use a new cutting tip. 
  • Decrease your cutting speed gradually until you see less dross.
  • Incrementally lower the cutting torch’s height.    

High-speed Dross

When you cut too fast, this kind of dross forms. The arc is left behind because of the torch’s faster speeds, resulting in hard lumps of uncut metal on the bottom of the plate. 

How to solve high-speed dross problems:

  • Use a new cutting tip, particularly if the cutter’s old cutting tip orifice is exhibiting symptoms of wear.
  • Decrease your cutting speed gradually until the dross level is reduced.
  • Increase the current, but don’t go beyond 95 percent of the AMP  rating of the nozzle.

Low-speed Dross

This is the dross that accumulates when your cutting speed is slow. You overwork the plasma arc in this situation. This reaches a wider span of metal since the cutting speed is insufficient. 

The incision automatically widens as the arc extends. The cut width reaches the point where the torch’s gas velocity is insufficient to blast away molten metal pieces. As a result, a heavy layer of dross forms on the plate’s bottom.
