Best Plasma Cutter Reviews
Do you ever find yourself in a situation where you have a lot of things to cut but don’t have the required tool to do your job properly? If yes, have a look at the Plasma Cutters. One tool for all, which can cut through a wide range of materials without any reluctance, varying from aluminum and copper to stainless steel and various others, a plasma cutter will be a great addition to anyone’s toolbox.
What are Plasma Cutters?
The basic function of a plasma cutter is to convert a gas such as Nitrogen, Oxygen, and Argon into the fourth state of matter (known as Plasma) for the purpose of metal cutting. The following information is vital in order so you understand how plasma cutters work.
Firstly, the gas is blown out through a very small nozzle for increasing its velocity. Then this high-velocity gas is sent through an electric arc which further enhances its temperature to such an extent which changes the gas into a highly efficient form of matter, plasma. As a result of this process, a super-heated torch is formed which cuts right through metals. The plasma also occupies the cutting surface, thus making it easy for the torch to do its work. Unlike other such processes, this one is a highly efficient procedure leaving very few debris. So when you are looking to save a considerable amount of time cutting materials, the plasma cutters come handy in this regard.
What is the difference between MIG Welding, TIG Welding, and Arc Welding?
One welding process can be differentiated from the other on the basis of its mode of functionality.
The Arc welding is a common welding process which uses an electrode to produce the required amount of heat. This electrode is basically covered with a flux which, on burning, produces a gas cloud. The gas cloud will then protect the weld and the electrode itself. There is no need of carrying a gas cylinder or a wire feeder as this electrode is more than capable of producing the gas by itself. Another thing which makes this process extremely versatile is the fact that to go from one material to another, users just have to change the electrode and BINGO. They just have to adjust the current accordingly and the welder will make wonders.
There is a vast variety of electrodes currently available in the market and all of them have specialized uses. So when this process doesn’t require an awful lot of equipment, arc welding is the least expensive when compared to its counterparts. The power source for this form of welding can either be alternative current or direct current. However, when it comes to welding thin metals, Arc welding requires utmost care.
An abbreviation of Metal Inert Gas Welding, MIG Welding is normally used for the higher end applications. In place of the electrodes, the MIG uses a thin wire coming from a spool of welding wire to burn, melt and fuse two metals together. In the MIG welder, there is a torch which in addition to delivering the filler material (wire) will also supply the shielding gas. You will need a gas cylinder and a wire feeder to cut metals with a MIG welder, so it is not as portable as the Arc welder. However, unlike the latter, the former process is extremely easy to learn even for newbies.
As per the type of metals you can weld with the MIG Welder, stainless steel, mild steel, and aluminum are the best matches. Lastly, MIG welding can be used to weld both thin and thick materials as users don’t have to worry about their own health while dealing with this welding tool.
Commonly known as Tungsten Inert Gas Welding, TIG is by far the most precise welding process. This is due to the fact that in order to maintain the intensity of your arch, you are provided with a foot pedal. It works just like the accelerator pedal on your car. If you’re working with thinner metals, where the level of intensity has to be reduced, just take your foot off the pedal. So whenever you need a greater control over whatever you weld, choose a TIG Welder
In such sort of welding equipment, the torch is equipped with a tungsten electrode while the shielding gas is Argon. As far as the welding process is concerned, hold an arc with the electrode and try to maintain a proper distance from the welding material at all times.
