Best Plasma Cutter for Metal Art Reviews

1. Hobart Airforce 500534 250ci Plasma Cutter – Powered by Household Current

Hobart Airforce 500534 250ci Plasma CutterThe Hobart 250ci is a lightweight plasma cutter, perfect for an artist cutting metal for sculpting. It is equipped with a built-in air compressor and is powered by standard household current (115 VAC). That means it won’t cause any electricity problems in your house/studio/work space.

One of the problems with plasma cutting is that the strong heat causes dross to form as the molten metal solidifies around the cut. Using oxy-fuel torch will cause a similar problem. An advantage of this Hobart plasma cutter, however, is that it creates a more precise cut than oxy-fuel. It also creates less dross than oxy-fuel cutting, so not as much cleaning up to do.

The machine will cut as much as a ¼ inch of mild steel. It operates using an electrical arc and compressed air. You can use it to cut different electrically conductive metals like aluminum and steel.

It features a lightweight inverter power supply, so it is quite convenient as a portable cutting system.

Compared to an oxy-fuel torch, this plasma cutter will help you finish your metal cutting tasks faster.

Using Steel in Sculpting

The advantages of steel for sculpture include malleability, durability, and relative cheapness. Many metal sculptors have made it their main sculpting material. The beauty of steel is that it easily lends itself to large-scale work while at the same time rewarding detailed handcraft.

With steel, you can contract out parts of the process to industrial fabrication companies. You can also do everything yourself in your artist’s studio.

Furthermore, steel is one of the most important materials in industrialization. It makes supports, armatures, frames, reinforcements, fixtures, jigs, machines, and various devices. It is therefore important for ambitious sculptors to develop at least a basic familiarity with the techniques of steel-working.

Types of Steel

You can get sculpting steel in a variety of cross-sectional shapes. These include:

-The U-shaped channel

-The L-shaped

-Angle Iron

-“I” beams

-Flat strap




-Tube (round, square, and rectangular)



When steel is thicker than 3/16 inches, it is called “plate”. Plate steel is often used for metal art.

Bar stock is round, square, hex, or flat, having various thicknesses of 1/8 inches and above.

There are other considerations as well other than the shape of the steel. For instance, one of the commonly used types of steel is mild steel. Mild steel contains more carbon, which makes it prone to hardening and tempering.

Another common type is stainless steel. It is rust-resistant and also harder and tougher than most unhardened steels. You can easily purchase it as sheet materials in gauges (that is thicknesses) starting from thin (28 gauges) to heavy (12 gauges and above).

Steel is typically galvanized – that is zinc-coated. Galvanized steel is impervious to rust. However, it interferes with the welding process, generating toxic zinc smoke when subjected to heat.

Steel is many times obtained as scrap metal containing unknown properties. To tell if what you have is tool steel or mild steel, grind on it. When ground on, tool steel produces a “rooster tail” of sparks. That is because tool steel has high carbon content. Mild steel will produce relatively few sparks.


How Plasma Cutter Works

Plasma cutting is a process of cutting through electrically conductive materials using a plasma torch. The torch produces an accelerated jet of hot plasma. Plasma cutting works on materials such as steel, aluminum, copper, and brass.

Plasma cutters are used in automotive repair & restoration, fab shops, salvage & scrapping operations, and in industrial construction. Thanks to its low cost and the high speed and precision cuts, plasma cutting is also widely used in small hobbyist shops as well as large-scale industrial CNC applications.

The Science

Plasma is one of the 4 fundamental states of matter. It is generated by either heating or subjecting a neutral gas to a strong electromagnetic field. The energy causes the gas molecules to break apart and the atoms to split.

You see, atoms consist of a nucleus surrounded by a cloud of electrons. The nucleus contains protons and neutrons. During the plasma generation process, the electrons separate from the nucleus. The energy of the heat also releases the electrons from the atoms, and they move around rapidly.

Electrons are negatively charged particles and they leave behind the positively charged nuclei. The positively charged nuclei are called ions. The collision of rapidly moving electrons with other electrons and ions releases immense amounts of energy. It is this energy that gives plasma its unbelievable phenomenal cutting power.

Practical Application

The plasma cutter generates its cutting power using an electrical arc that is passed through a torch lead. The arc may come from a transformer or an inverter power source. Flowing through the torch’s tip, the electrical arc meets with compressed gas (oxygen or nitrogen or argon or compressed air) being pushed through a constricted orifice in the swirl ring.

The electrical arc causes the high-pressure gas to superheat and turn to plasma. The plasma is then transferred to the electrically conductive work piece conducted the machine via the ground clamp. The superheated gas (plasma) then cuts the metal. The cut’s size depends on torch tip size and angle or distance torch is held at.

The ability to cut thicker metal is controlled by adjusting the amperage settings of the plasma cutter. Higher amps make the cut hotter and therefore allow you to cut thicker metals.

Key consumables that you will have to replace often are the nozzle and electrode tip. Replacement frequency depends on the extremeness of your cuts, your skill level, and the temperature range you are cutting at. Now and then you may have to replace the swirl rings too. Other consumables include shield and retaining cap.


After reviewing the five plasma cutters, we chose the Hypotherm Powermax 45 XP as the best of the bunch. It is small, lightweight, and portable. It features patented drag-cutting technology which makes cutting easier even for beginners.

For the runner’s up, we picked the Miller Spectrum 625 X-Treme, another cutter which packs big cutting power in a small package.

The best plasma cutter for the money is Lotos LTP5000D. The only reason we are not nominating it as the best is because it is in a much lower price range than the other too. It has many attractive qualities such as dual voltage, quick setup and Papst advanced cooling system.
