2. Hobart 500564 Airforce 12 Ci Plasma Cutter – With Built-in Air Compressor

Hobart 500564 Airforce 12 Ci Plasma CutterOnce you purchase the Hobart 500564, you will not need to make any extra purchase, as the unit comes with everything you need. It has a built-in air compressor, so you won’t have to purchase one separately.

Features

-Built-in air compressor

-Faster than oxy-fuel cut

-No gas pressure settings for flame tuning required

-Smaller heat-affected zone

Using the Hobart 500564 cuts metals faster than using oxy-fuel. Oxy-fuel cutting, also known as flame cutting, involves a torch with a fuel gas (typically acetylene) which is used to preheat the metal.  Plasma cutting is a powerful process which is great for high speed cutting. Plasma cutting is twice (or more) as fast as oxy-fuel cutting.

Plasma cutting is useful for cutting steel plates, though the speed is lower when working on heavy steel profiles. While this fast cutting speed is highly beneficial, it has its downside: the immense power generated by the process imposes a high amount of pressure on consumables (nozzles) and shop floor safety. As a result, though faster than oxy-fuel cutting, plasma cutting has higher operational costs.

Plasma cutting entails creation of an electrical channel of superheated, electrically ionized gas (known as plasma) from the plasma cutter, through the work piece, forming a complete electrical circuit back to the cutter through a grounding clamp.  This feat is enabled by compressed air which is expelled through a focused nozzle at high speed toward the metal you are cutting. The Hobart 500564 features a built-in air compressor.

Since this Hobart has a built-in air compressor, you will not have to make an extra purchase. Once you buy the Hobart, you have everything you need. While having an air compressor and plasma cutter in the same unit increases the cost price, it is worth it because of the convenience. Cutting duration is determined by how much air the unit is able to provide.

The Hobart 500564 provides a more precise cut, with thinner kerf, and less slag to clean up. The kerf is the width of the material removed when cutting. Slag is the accumulation of hardened metal around the perimeter of the cut. Too much slag leads to costly downtime as you have to do post-cut cleanup.

This cutter has a smaller heat-affected zone, hence there is less warping. Furthermore: no gas pressure settings for flame tuning required.

Pros

-Convenient buy since has built-in air compressor

-Fast cutting

-Thinner kerf

-Less slag to clean up

-CNC power source, compatible with CNC table

The HeroCut Cut55 is equipped with a non-HF, non-touch pilot arc. HF stands for “high frequence. HF plasma cutters ignite their pilot arc using a high frequency. In HF machines, the nozzle and the electrode are in a fixed position. The HF arc jumps the gap, air expelling the arc from the nozzle.

Pilot arc plasma cutters, such as the CUT55, use contact start and a have a moving electrode inside the torch (the electrode is not fixed, is the case with HF machines). This technology is more recent in the plasma cutting field than HF. Pilot arc plasma cutters help reduce interference with electronics while cutting. They also provide a stable cutting arc.

Furthermore, they ensure a longer consumable life since they do not touch the metal when starting the arc. Pilot arc plasma cutters are more cost effective in operation. They are non-touch, which means they can start the arc without touching the metal you are working on. As a result, they are customer-friendly and are in wide usage.

The HeroCut CUT55 also features a CNC power source and is compatible with CNC table. CNC stands for Computer Numerical Control. A CNC plasma cutter is one whose motion is directed by a computer based on numerical codes in a program.

Handheld plasma cutting, cannot achieve the same kind of part accuracy or edge quality for most metal fabrication as CNC plasma cutting. Since CNC cutting is mechanized, you can achieve precise cuts.

Plasma Cutters Buying Guide: Factors to Consider When Shopping for a Plasma Cutter

  1. Input power

Ensure that the amperage ratings of the plasma cutter you are buying can be met by the electrical outlet in your workshop or garage.

  1. Cutting Speed

It’s important to know the cutting speeds the plasma cutter can manage for metals of varying thicknesses. This will help you determine the rate of production the machine can deliver.

  1. Duty Cycle

This is a percentage figure which explains how long a machine operates before requiring a break to cool down. It is calculated in durations of 10 minutes. For instance, 40% duty cycle means the machine operates for 4 minutes and cools down for takes a 6-minute break. A higher duty cycle is preferable, especially if you are using a mechanized plasma cutter not hand-held.

  1. Contact Start vs High Frequency Start

There are two ways to initiate the pilot arc: contact or high-frequency start. If you are using the plasma cutter near an electronic device such as a TV, the HF start technology will cause interferences. Contact start plasma cutters do not cause any interferences.

Furthermore, contact start technology provides a visible pilot arc, enabling you to position the torch more accurately.

  1. Weight and Size

Weight and size matter if portability is an important factor for you, for instance if you often travel back and forth with tools. DIY hobbyists and those working on a small-scale are more likely to prioritize portability.

Final Thoughts

In this article, we have reviewed ten different machines based on varying parameters. Some are more expensive than others to ensure all budget levels are catered for. Some are compatible with CNC tables while others aren’t. Some have built-in compressors while others don’t. Pick the one you like based on your preferences, requirements, and constraints.
