ARCCAPTAIN Color-coded Tungsten Electrodes

This 10-pack of 2% Lanthanated tig tungsten electrodes 1/16"x7" (Blue, WL20/EWLa-2) is a top-quality product that adheres to Standard AWS A5.12M/A5.12:2009 and DIN EN 26848 GB/T 31908-201. All tungsten in this pack has 100% traceability, ensuring its quality and origin.

These high-performance tungsten welding electrodes are manufactured to exact specifications and precise size. They have the ability to resist thermal shock, providing the user with fast arc striking and a low burn off rate without spreading. Even under heavy amps welding on thick aluminum plate, these electrodes do not split.

The lanthanated tungsten tig electrode is non-radioactive, offering good electrical conductivity, requiring lower amperage, good ductility, and excellent arc stability. These electrodes are ready to help you make the perfect and consistent weld.

The 2% blue lanthanated tungsten electrodes are ideal for both DC and AC applications for welding various materials such as aluminum alloys, magnesium alloys, nickey alloys, copper alloys, titanium alloys, low-alloyed steels, and more. They are a premium tig tungsten for TIG welding suitable for beginner, intermediate, and professional TIG welders.

The 2% Red Thoriated Tungsten Ideal for DC applications and for welding Copper alloys, nickel alloys, titanium alloys, and stainless steels etc. The premium tig tungsten for TIG welding for the beginner, intermediate, and professional TIG welder.

This package of tungsten electrodes includes 10 tungsten electrodes with a Tungsten Electrode Size of 1/16" x 7" (1.6mm x 175mm). The electrodes are vacuum-packed to prevent oxidation, allowing for long-term preservation. Overall, this product offers a reliable and high-quality option for TIG welding projects.

Technical Details

Lanthanated Blue Tungsten and Red Thoriated Tungsten are two types of tungsten electrodes commonly used in Tungsten Inert Gas (TIG) welding. Both electrodes offer unique characteristics and advantages. Here's a comparison between the two:

  1. Composition:

    • Lanthanated Blue Tungsten: Lanthanated tungsten electrodes contain a small percentage of lanthanum oxide (La2O3) mixed with tungsten. The addition of lanthanum improves the overall performance and stability of the electrode.
    • Red Thoriated Tungsten: Thoriated tungsten electrodes contain thorium oxide (ThO2) mixed with tungsten. The thorium component provides excellent arc stability and facilitates easier arc initiation.
  2. Radioactive Content:

    • Lanthanated Blue Tungsten: Lanthanated tungsten electrodes are non-radioactive. They do not contain any radioactive materials, making them safe to use without any health concerns.
    • Red Thoriated Tungsten: Thoriated tungsten electrodes contain thorium, which is a weak radioactive material. While the radioactivity levels in thoriated tungsten electrodes are relatively low, it is still important to handle and dispose of them properly.
  3. Performance:

    • Lanthanated Blue Tungsten: Lanthanated tungsten electrodes provide excellent arc starting and stability. They have a lower amperage range and are suitable for both AC (Alternating Current) and DC (Direct Current) welding. They offer good service life and are commonly used for general welding applications.
    • Red Thoriated Tungsten: Thoriated tungsten electrodes have excellent arc stability, making them ideal for DC welding applications. They have a higher current carrying capacity, making them suitable for higher current applications. However, due to the radioactive content, thoriated tungsten electrodes are being phased out or restricted in some countries due to health and environmental concerns.
  4. Color Coding:

    • Lanthanated Blue Tungsten: Lanthanated tungsten electrodes are typically marked with a blue band at the end to indicate their composition.
    • Red Thoriated Tungsten: Thoriated tungsten electrodes are marked with a red band at the end to indicate their composition.

Arccaptain Lanthanated Blue Tungsten electrodes are available in two sizes, typically measured in inches. The difference between different inch sizes of Lanthanated Blue Tungsten electrodes lies in their applications, current carrying capacity, and suitability for specific welding tasks. Here are the key differences:

  1. Diameter/Size:

    • Lanthanated Blue Tungsten electrodes are available in different inch sizes, such as 1/16", 3/32". The size refers to the diameter of the electrode.
  2. Current Carrying Capacity:

    • The diameter of the Lanthanated Blue Tungsten electrode affects its current carrying capacity. Generally, larger diameter electrodes can handle higher amperage levels compared to smaller diameter electrodes. For example, a 3/16" electrode can carry more current than a 1/16" electrode.
  3. Welding Applications:

    • Smaller Diameter (e.g., 1/16"): Smaller diameter electrodes are suitable for low current applications and thin materials. They are commonly used for delicate welds, precision work, or welding thin sheet metal.
    • Medium Diameter (e.g., 3/32"): Medium diameter electrodes offer a balance between current capacity and control. They are versatile and can be used for a wide range of welding applications, including general fabrication, maintenance, and repair work.
    • Larger Diameter (e.g., 1/8"): Larger diameter electrodes are designed for heavy-duty applications that require higher amperage levels. They are commonly used for welding thick sections, heavy structures, or when higher heat input is required.
  4. Arc Stability and Performance:

    • The diameter of the electrode can also affect arc stability and control. Smaller diameter electrodes tend to provide better control and more precise arc characteristics, while larger diameter electrodes may offer increased stability and better arc initiation in high current applications.

There are several types of tungsten electrodes used in welding, including:

  1. Pure Tungsten (Green Tip): Suitable for AC welding of aluminum and magnesium.

  2. Thoriated Tungsten (Red Tip): Ideal for DC welding of steel and stainless steel. Contains thorium, which can be radioactive.

  3. Ceriated Tungsten (Orange Tip): Works well for both AC and DC welding, especially on thinner materials.

  4. Lanthanated Tungsten (Gold Tip): Suitable for both AC and DC welding, with good performance on aluminum and alloys.

  5. Zirconiated Tungsten (Brown Tip): Used for AC welding, particularly for applications involving high amperage and when a stable arc is required.

  6. Rare Earth Tungsten (Gray Tip): Offers excellent arc stability and is suitable for both AC and DC welding.
