The tungsten electrode is used with three different welding processes or procedures. These electrodes are made for the; Plasma arc, Gas tungsten arc, and Tungsten inert gas welding processes. This equipment has been designed to be used with the tungsten electrode.

This tungsten stone is made up of a shiny metal white in coloring. This stone is known for having the capability of maintaining one of the highest melting points when it comes to elements. They are also known for having very high boiling points for a metal. These aspects are what makes them unique. Because of their abilities to withstand very high temperatures and their durability, they are a must for some welding techniques.

The electric arc is the light that you see when the welder begins to cut the metal. The electric arc produced when the tungsten electrode has voltage coming through from the power supply unit. This arc occurs as the current passes through the electrode and onto the work material or source material. The heat from the arc allows the welder to cut the metal. The heat from the tungsten electrode brought to the work area, produces the molten metal as it cuts.

When you need to purchase your electrode for any of the welding types mentioned. You must be sure that you are choosing the appropriate electrode specification for the job. There are many factors that you must consider when you purchase the tungsten electrode for your work. Although there are many more, within this article we will discuss the most basics, such as:

• Make sure you get the appropriate diameter or length
• Make sure that you have the correct current range
• Make sure that you have the International Color Coding Chart
• Make sure you they have met the Standards for your country.

Having the correct diameters or lengths is important and must be tested to ensure that they are in fact the correct ones for the job. They come in a variety of sizes and lengths. The most universal length would be 7.00” (17mm). You can purchase several sizes close to the length you need, just in case you may need to readjust to get the very best in outcome for your job.

Having the proper current is vital, because you don’t want to have too much or it will melt the electrode. If your current is unsatisfactory, this will lead to a arc that is unbalanced or unsteady.

International color coding charts have been organized not only by color, but also countries. There are three major areas that have been differentiated by the color chart. The United States, Europe, and Japan each have their own colors or paint strips to mark for different tungsten electrode or material.

The standardization of the tungsten electrode are not the same for the United States, Europe, and Japan. They each have their own packaging standards, their own dimensions, and manufacturing set standards that are unique to each area.

They each have their own coding for the material to let the buyer know which standards they are purchasing for instance; the American standard is ANSI/AWS A5.12. If you are purchasing an electrode from Japan it would have JIS written somewhere on it and if buying from Europe it would have ISO 6848.

It is basically the same for anyone purchasing anything, check and recheck the specifications before you buy your next set of tungsten electrode.
