Hypertherm has a reputation as an industry leader because it focuses entirely on cutting technology, rather than another aspect of welding technology. The Hypertherm Powermax 30 embodies this pedigree throughout the machine. The lightest plasma cutter in its class, it weighs only 30 lbs, yet draws 30 amps, enough to cut through ⅜-inch steel with ease.

An onboard air compressor provides ample pressure to clear the cutting channel, and the Hypertherm Powermax 30 features dual 120 and 240 volt power inputs. Hypertherm's Drag Cut technology makes starting the arc easy, as all that is required to trigger the arc is touch and pull with the torch, and it's ready to go.

Hypertherm intends to use the PowerMax 30 for small tasks and portability, so it does not include a computer control connection on the Powermax 30 for CNC work. The power system of this machine comes with a 3-year warranty. The machine is CSA certified for use in the Americas and Asia (except China) and is also available for certified work in Russia, Ukraine and Serbia.

The Hobart Airforce 12ci plasma cutter is designed for maximum portability. It's a light machine that runs on 120 volts and has just enough power to cut 3/16" steel, which is good enough for cutting brackets, repairing panels, and other small tasks. It's perfect for HVAC professionals and others who need a plasma cutter that they can bring into the house and plug into the homeowner's power supply.

Although this is a lightweight plasma cutter, it does have some advanced professional features. The rear airflow control will continue to blow air after the cut is completed for faster cooling. Hobart's Fan-On-Demand runs cooling fans only when needed to save power and prevent dust and debris from accumulating inside the Airforce 12ci enclosure. Even beginners will find this plasma cutter easy to use, with guided arc start and a beautiful Miller ergonomic torch.

Hobart is a leader in the metalworking industry. Its machines can be seen anywhere there are welders and metalworkers. Although small and light, the Hobart Airforce 12ci is a vital professional tool with a built-in air compressor and comes with a 5-year warranty.

The Lincoln Electric K2806-1 Tomahawk 375 Air Plasma Cutter delivers up to 25 amps of cutting power. Built to industry standards, this machine is geared toward the DIY maker, not the professional who does high-volume work on a daily basis. Its compressor is rated for an average working pressure of 70 PSI, which in real life means it runs between 50 and 80 PSI. Some owners recommend using an outside air source for heavy cuts around 1/4" max, you may need more pressure like 100 PSI.

Lincoln says the K2806-1 Tomahawk 375 Air Plasma Cutter cuts quickly right out of the box. The bottom end draws 10 amps and lets you cut sheet metal, but you'll need to move quickly to avoid blowing the edge off when cutting thin objects. Digging up to 25 amps will get you through steel 1/4 inch at a time to cut through trailer frames and pipe fences.

All controls on the Lincoln K2806-1 Tomahawk 375 Air Plasma Cutter are located on the front panel for increased productivity. Airflow rates can be monitored and adjusted at the front, rather than having to lean back like some other designs.

The Forney 250P Plus with built-in air compressor is a lightweight plasma cutter ideal for DIY workshop use and light duty jobs. Because it runs on a 120 volt input, it can plug into household current. It may be useful for professionals who make house calls for appliance work or HVAC duct repairs.

Equipped with a torch start, it is easy to start and use, but does have a lag time that makes it an issue for high-volume cutting. It takes a few seconds for the arc to start after the trigger is pulled, and then a few more seconds before the arc is hot enough to start cutting. For individual cuts done at intervals, this isn't a huge issue, but the Forney 250P Plus isn't suitable for frequent, quick cuts. However, it is designed to run on so-called "dirty" generator electricity, so it can be used in remote areas.

Forney integrates the air dryer and pressure regulator directly into the machine, and the cutter is fully automatic with no need to set controls. Weighing 43 pounds, it's light enough to take with you anywhere, and can cut ⅛-inch steel at 12 amps. Forney has designed a storage compartment into the housing for supplies and backs the 250P Plus with a 3-year warranty.

Thermal Dynamics is the Hypertherm brand sold by ESAB, which means the machines are industrial quality and aimed at professionals. This is reflected in the higher price range and relatively conservative output ratings. The AirCut 15C weighs only 29 pounds, very light for a machine with a built-in air compressor. In fact, this is about 50% of the weight of an average 15 amp plasma cutter. Thermal Dynamics claims a 25% higher cut rate than any other plasma cutter in its class.

The Thermal Dynamics AirCut 15C will go straight through 3/16" steel plates. Higher working capacity, superior build quality and ESAB 1 year warranty justify the higher price range for professionals. The machine is rated for a 35% duty cycle at 15 amps. With a high cut rate and a 50% duty cycle at 12 amps, professionals can really cut a lot.

The Thermal Dynamics AirCut 15C, with its lightweight 120-volt power supply, is ideal for the professional craftsman who needs to complete work in the client's home.
