Introduction:

There are two main ways of arc welding, namely TIG welding and MIG welding. TIG welding is done with the help of special machines, designed to create a perfect weld between two metals.


TIG welding machines:

TIG welding stands for welding with Tungsten Inert gas. This type of welding is used with stainless steel and aluminum. TIG welding therefore requires welding rods. Usually this rod is held in one hand and an electric torch is held in the other. The function of this electric torch is to melt both the work piece and the rod at the same time. To protect the weld from environmental effects, Inert gas is blown in the weld. Since this kind of welding is very popular, many manufacturers are launching new welding machine equipments on regular basis. There are a few questions you need to answer before choosing any one design. The first important consideration is the purpose of your use. If your use on welding machine is limited then you can consider easy to use and affordable products. However if you are looking for machines that are versatile and which can weld faster in less amount of time then you can go in for units that work faster, and with equal degree of efficiency. Such machines also provide you with software programming facility. Another important area of consideration is the power source. To use many materials the best option is to go in for a combination of AC/DC machine. Though many more options in terms of power source are also available. The other choice that you need to make is between portable welding machine or fixed welding machines. If you travel frequently because of your work then your best possible deal will be to go in for a portable welding machine. These machines come in many different designs and sizes.


Precautions:

Safety comes first and therefore using appropriate protective clothing is very important while working. Extreme precautions need to be taken while installing and handling the equipments. Reading the user manual before application is very important. The machines should also be stored properly when not in use. In case of injury, first aid should be taken immediately.

With the help of few precautions and your own caution, welding machines can be operated safely by any expert welder.
