Welding machines are essential for good welding process and an industry that uses welding process needs proper welding equipment and tools. Here, in this article, we are going to see the three best welding machines and its uses. They are none other than tig welders, plasma cutter and arc welders. This three welding process are widely used in many industries, for example, when you see tig welding, it is a welding process that allows for stronger and higher quality welds and most of the engineers prefer for gas tungsten arc welding because it has low hydrogen properties and matches well with the mechanical and chemical properties of the base material. Arc welding was the old type of welding process, but still now it is popular due to its weld characteristics.

Plasma cutting uses new technology and it cuts steel and other metals of different thickness. Ok, let us now proceed into these welders and its uses, and also let us see from last to first. We will start with plasma cutter, the modern industry depend upon heavy metals and alloys and metals are extremely strong and at the same time it is also has some weak characteristics. To cut a metal is not so easy and that too it needs to be cut precisely so how can you cut and manipulate the metals precisely. For all these questions, a new machine was introduced and it is called as plasma cutter. When you see conceptually, it is extremely simple and come in all shapes and sizes. It is compact and used largely in auto shops and car manufacturers. When you buy this welding machine, consider the way it is made and look for the one that cuts most of the time.

When you look for this machine consider what you will be cutting most of the time and do not have a one that undercut the metal you are working with most of the time. Check the capacity of the machine you are going to buy and also get a plasma cutting machine that cuts faster than others. The myth that surrounding the arc welder is that it is more expensive and can be used only by large companies, but it is not true, the arc welding machine that exists now are much more affordable and can be used by all types of industries. Find which arc welders are you going to buy and see its demonstration and learn how to use them so that you can get a type you need. The last, but not least is tig welders and tig welding depend upon consumables such as tungsten electrode and it is a specialized welder that cannot be found in many stores and with the help of this welding machine, you can weld two different pieces of metals that are thick and can weld together without using filler.

So when you buy these machines, look for the one that are best and quality in both price and piece. Get a good machine and weld safely.

What is the use of tig welder?

In this article, we are going to discuss the use of tig welder and before going into brief, let us see a small introduction about the tig welding and its advantages. When you give importance to the appearance of products, your choice has to be tig welding and it may not be suitable for some welding requirements, but it has many advantages than other welding products. In this welding method, the welding arc is created between the electrode and the metal that is going to be welded. Generally the non consumable electrode called tungsten electrode is used due to its high melting point and good electrical characteristics. To weld any metal some sort of heat is required and that heat is produced by the arc and after that the shielding gas is fed through torch.

Some tight form of bonding is required and that type of tight bonding is produced by tig welding and it meets the high quality and code requirements. The tig welding process affords a better and quality welding than its competitive welding process called mig welding. When you go to a shop for selecting TIG welders, you should be familiar with the power and sophistication of your job. You should calculate the volume of the job so that buy a tig welding machine based on your work requirement. Most of us will be in a confused state of mind while selecting the power source and will be thinking whether to use DC power source or AC power source. Metals like aluminium and magnesium can be welded by using AC output, whereas metals like steel and stainless steels need DC output. It is advisable to buy a tig welder that is combination of both so that you don't need to run for any ac or dc source.

In market, you can find five tig welding machine series and each type are of inverter type that is Infineon IGBT.

All you need to know in arc welder

Arc welding is the oldest type of welding and the electric arc is created by using the welding power supply between an electrode and the base of the material. This process starts to get developed after forge welding and nikolai bernardos was the one who first created the electric arc welding method. Let us thank him for giving this wonderful welding process because he is the one who puts a foundation on this process. Arc welding gets developed during the middle of the century and now it continues to be popular today. Let us first see how to choose an arc welder. When this was developed, everybody had a thought that it is an expensive machine that can be used only by top companies, but now no one can say that this machine is an expensive one and it has been designed in such a way that everyone can enjoy the usage of this machine. It has become much more affordable and every user who uses this machine enjoys its convenience.

Look for an arc welder that is approved by the American welding society and decide your purpose of using it. Decide your job plan and according to that select a welding machine that suits your demand. It is very good if you visit any welding show because once you visit those shows you can get an idea of its features and can also know the uses and purposes of those machines. As said above, select your area of workplace and then buy the machine. For example, if you have planned to use it for an indoor project such as in car garage, protect your torches from wind by placing a barrier so that your welding torch doesn’t get affected from wind. Flux core arc welding machine is best if you use it for outdoor projects and it more portable and requires less clean up on metal surfaces.

Give importance to trigger mechanism of your welding machine because a welding machine without any trigger mechanism is dangerous if it is used in indoors. Choose your amperage and this factor depends upon the metal you are working with. For example, 5mm steel needs 180-amp welder and 2mm need 90 amp welder so the thickness of the metal is very essential. When you start to work with this welding machine, try to secure it in a place such that there are no flammable materials nearby. Turn your machine and set it to required amps and if continues to stick, try to improve the amperage. Keep the electrode in a minimum distance or else, it will make noise and get sticks to the metal. Once you feel comfortable, start working with your welding process.

Buy a metal with correct amperage and remain safe while welding by using welding safety items such as welding helmets and welding gloves. Keep your arc welder in a flat platform so that the position does not get disturbed and you can weld the metals smoothly.
