Key Features

Cable management strap, thermal overload protection, wind tunnel technology, post-flow air cooling, fan-on-demand, new ergonomic torch, multi-voltage plug (MVP) are just a few of the features included in the base unit.

Build Quality and Design

The Hobart Airforce 27i is available in a simple and compact design. Although the design is very simple, it is very strong and reliable. The user will be able to work with the unit for hours thanks to its ergonomic design. The product looks a little bulkier because of the inverter inside. However, it only weighs 32.1 pounds including the ground clamp, torch and inverter. With such a weight, the 27i is very portable. The design also comes with a heat-resistant handle.

For durability, Hobart plasma cutters are created with high quality heavy gauge steel. Aluminum is also used in creating some parts of this product. Strong plastic material that are fire resistant are also used to house the wiring. The product features thick pipes as well.

Ease of Use

Ease-of-use is one of the strongest selling points of Hobart plasma cutters. In the first instance, this product is very easy to set up and utilize. It is as simple as plugging in the unit and getting the compressed air supply connected. Pull the trigger and cut after grounding the work piece. It will not take the users of this product much time to decide where to plug in the pipes, torch connectors, and plugs because they will see the correct setting thanks to the markings on the product.

The unit uses two voltage, 112V and 240V. Either of the voltages can be used in operating the product depending on what is being cut. The user can plug into any of the voltage powers depending on the voltage that serves him better. You do not need to do any other thing in order to get the system worked in the voltage you want. All you have to do is to plug into the voltage you want and the system will work under the required voltage.

Another feature in this product that makes for ease of use and portability is its convenient cable management strap for wrapping the wiring. The system will be easy to move when the wiring is wrapped as there will be no obstruction by anything.

Cutting Mechanism

Cutting with this product is quite easy and very efficient. It does not require any flame tuning or gas pressure settings. You will not be required to preheat the metal material you want to cut before you will be able to cut it. You only have to pull the trigger for the internal cutting mechanism to go into action. The unit generates the right Direct Current’s magnitude required for a neat and faster cutting using electrical inverter.

Hobart Airforce 27i can be used to cut different types of steel and aluminum thanks to its amperage settings. You set the amperage to suit the type of metal that you are cutting. With the machine, you will be able to cut not just thin sheet of metal but 3/8″ and sever 5/8″ steel plate.

The product is highly versatile in usage. Even engine driven welders can cut with this product.

Safety and Cooling Features

It is safe to cut with the machine thanks to a number of safety features it comes with. First, there is no possibility of accidental cutting as you cannot accidentally press the trigger. It includes a protective trigger guard. So, before you can cut, you have to lift the guard and intentionally pull the trigger.

Secondly, the unit does not overheat. It features a thermal overload protection switch which immediately turns off the system when the unit is functioning under the stipulated duty cycle and threshold temperature. In this way, it protects both the user and the machine. The process is automatic and thus even if the user does not notice that the system is overheating, there is still no cause for alarm.

The product also features the post-flow air cooling and wind tunnel technology which are the two main cooling and maintenance features in the unit. The former works by reducing the tip’s temperature as well as the temperature of the nozzle as soon as you stop cutting. This arrangement helps to prevent accidents and increases the durability of the consumables. The latter prevents dust from entering into the internal parts. It also cools them by passing cool air through the tunnel.

Another maintenance feature that compliments the function of the wind tunnel by protecting the unit from dust particle is the fan on demand. With these features, the product can be used for cutting even in tough and dusty environments.
