Tig Gas

why tungsten is not generally used for the electrode in tungsten inert Gas Welding?

why tungsten is not generally used for the electrode in tungsten Inert Gas welding?
What is the effect of step pulsed DC supply in TIG welding.What is the significance of pressure & current sequence in resistance welding?

Your question is confusing because tungsten is generally used as the electrode for tig welding. This is because it has the highest melting temperature of pure metals. In some cases tungsten alloys are used.
