There many varieties of welding equipment which are used for different purposes. One of the most important things for these welding and cutting equipments is the water cooler. The work of water cooler is to cool the welding machines which get heated while welding. The welding heats up the torch of welders which needs a supply of water. Apart from these welding equipments you also need a welding helmet which protect for eyes and face from any harmful burns or sparks.

Plasma Cutter:

One of the most important things used for any construction is the metal. Metals play a vital role in constructing buildings. Now to cut the metals you need a cutter. There are some cutters which doesn’t cut all kind of metal. But there is one cutter which can cut all the metal in no time. It is known as plasma cutter. These cut the metal with the help of plasma torch. These are utilized for cutting steel and all conductive metals. These cutters need high voltage and are epitomized of plasma gas. To make use of this first the plasma gas is created. The advantage of this is it can cut any metal at high speed. While cutting the inner surface remains cool and this does catch fire in any circumstances.

Welders:

You can find many types of welders for welding objects like steel, aluminum and many other metals. Some of the welding equipments are Mig weld or GMAW, Tig weld or GTAW, Stick weld or SMAW, Spot weld and Arc weld. All these have different purpose and used for different industries. You can also find multi purpose unit which consist of plasma cutter, Mig weld, Tig weld and stick weld. They are the most versatile equipment because the space they need is really very less. Buying has made easy by shopping online. Now you can search and learn more about this product on net. Almost all the products have advantages and disadvantages. So buy the equipments which are very useful in your daily life.

Mig or GMAW weld:

This metal inert gas is other wise known as Gas Metal Arc weld. These utilize the wire electrode and also needs constant voltage supply. These are mostly used for building aircraft and automobiles. These are the easiest among the welders. You need a lot of practice before welding metals.

Tig or GTAW weld:

The other name for tungsten inert gas is the Gas Tungsten Arc welding. These are used for welding steel and non ferrous metal. These are easy to mechanize and automate. These are utilized in chemical and instrument industries. This gives a clean finish and are bit difficult for the beginners. These are highly pricey than the Mig welder and other welders.

Welding Machine is equipment, which is used to weld or joint two metals or alloys together using another metal component as filler. Usually structure-less metals and alloys are joint using welding machines to give them desired shape and make them sturdier than they would be if it were a single piece.

These machines are available in different sizes as per their utility. A large size machine would be used in a factory and a handy machine is available for domestic purpose. Types of machines that are available in the market vary from Arc welding machine, Fusion-welding machine, Plasma Cutting machine, Resistance welding machine, Solid State Welding machine and less known types are Induction and Thyristorised welding machines.

Among all the types, Arc type machines are the most efficient and effective. According to the type of material used to weld, they are broadly classified into three categories.

Common most is the Manual Metal Arc mechanism. The tool looks like a stick, which performs the function of a main electrode, and it is covered by a flux that prevents it from oxidization. With the help of electricity, the electrode melts itself continuously for welding the metal. This equipment is mostly used for small tasks. This kind of machine is usually used in construction industry, maintenance and repair of small metals, cutting and making holes in steel products and rebuilding fixtures.

Second form is a Metal Inert Gas mechanism which is a large bobbin like formation. It is a single piece of equipment that includes a mix of argon or helium gas or both used along with the heated electrode to camouflage the metal from rusting. This makes the task easy and quicker. Metal Inert Gas equipments are mainly used in shipbuilding, power plants, aerospace equipments, automobile industry, bridge constructions and refineries.

The third kind is Tungsten Inert Gas, which has a single electrode, and the protective material is provided by another resource. The electrode does not thaw out as it has an additional tool to give it protection. This type of mechanisms is used in large factories where it is impossible to use other type of welding machines. Principally, Tungsten Inert Gas machines are used in power plants, construction industry, aerospace industry and manufacturing industry for more robust and specialized welding.

Apart from these, other type of welding machines that are available in the market are:

Carbon Arc, which is used for welding alloy steel and water jet cutting.
Orbital or Tube Arc is used in casting, shipbuilding, automotive industry etc.
Plasma Arc is used for welding of surgical instruments, food industry, dairy industry etc.
Stud Arc is mostly utilised in fabrication and machining.
Submerged Arc is chiefly used in industrial welding and pipe welding.

Any industry usually uses a combination of any of the above machines as per requirement. Welding machines are easy to use but is a complex piece of machinery and hence should be operated under expert guidance.
