1. 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 very small 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 from the world’s fi nest 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™, Muliti-Strike™, SYLVANIA, Weldcraft®, and CK Worldwide®.

2. DETERMINE THE BEST TUNGSTEN/TUNGSTEN ALLOY FOR YOUR APPLICATION
Since the development of the TIG welding process, many improvements have been made in the production of electrodes. Most signifi cantly 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 the arc time of the electrode and improving arc stability.
Each oxide has a diff erent physical characteristic aff ecting tungsten perfor-mance. Electrodes are color coded, indicating the type of oxide used in the mix. Note that color-coding is not standardized for all mixes and varies from the U.S. to Europe and Japan.
For most hand-held welding operations, Arc-Zone® recommends the ArcTime™ Hybrid Tungsten Electrode. For other applications, particularly automated weld-ing, the best way to determine which tungsten alloy is best suited for your application is through testing. The following list is provided as a guide.

Other tungsten blends that are not common but you may see in the market place include: 4% Thori-ated, 3% Thoriated, and 1% Lanthanated: Color codes are not standardized in the U.S. Again, pur-chasing from a trusted source is important as manufacturing methods can greatly aff ect tungsten electrode performance.
3. SELECT THE PROPER SIZE
Tungsten is generally sold in packages of 10 pieces in a variety of standard diameters from .020” (.5mm) to .250” (6.4mm), and in lengths of 3, 6, 7, 12, 18 and 24 inches. The most common length is 7.00”(175mm) in the U.S. and 6.00” (152mm) in Europe. The most common diameters are: .040” (1.0mm), 1/16” (1.6mm), 3/32” (2.4mm), I/8” (3.2mm), 5/32” (4.0mm), and 3/16” (4.8mm).
Electrode diameter aff ects welding performance and weld bead shape. Again, the best way to determine which tungsten is best suited for your application is through testing, however, the following chart should serve as a general guide.
Diff erent electrode materials will vary slightly from these guidelines. Use of other gases will also change the recommended currents. Use this chart as a general guide. Also keep in mind that for a given amount of amperage, larger diameter electrodes will last longer but will be harder to start. Excessive current will cause the electrode to melt and drop off . Insuffi cient current will lead to an unstable arc.
