Selecting the proper tungsten electrodes greatly improves weld quality and productivity while lowering

costs for your Gas Tungsten Arc Welding (GTAW/TIG) and Plasma Arc Welding (PAW) operations.

Choose Electrodes from a Trusted Source

Although tungsten electrodes may look the same from one company to another,

high-quality tungsten has been manufactured to ensure a dense grain structure

which allows for better migration of oxides to the tip of the electrode .

With high-quality tungsten, you'll experience easier arc starting, improved arc time

and better weld quality with minimized contamination . Arc-Zone .com's ArcTime™

and Amplify™ brand electrodes are sourced from the world's finest producers and

meet or exceed ISO 6848 and AWS A5 .12 standards . Arc-Zone .com ® delivers the industry's most

complete line of premier tungsten electrodes including: ArcTime™, Amplify™, CK Worldwide™,

DGP® Multi-Strike™, Miller®, and Wolfram® .

Determine the Best Tungsten for Your Application

Since the development of the TIG welding process, many improvements have been made

in the production of electrodes . Most significant is the addition of oxides to pure tungsten,

creating tungsten alloys that provide the same level of emission as pure tungsten at much lower

temperatures, improving starting performance of the electrode, arc stability, and tip life .

Each oxide has a different physical characteristic affecting tungsten performance . Electrodes are

color coded, indicating the type of oxide used in the mix . Note: Color-coding

is not standardized for all mixes, and it varies from the U .S ., Europe, and Japan .

For most hand-held welding operations, Arc-Zone® recommends the

ArcTime™ Hybrid Tungsten Electrode . For other applications, particularly

automated welding, the best way to determine which tungsten alloy is best

suited for your application is through testing . The list on the following page

is provided as a guide .
