WP018X7 - Weldcraft EWP Green Pure Tungsten Electrodes 1/8" (10-Pack)

Miller Weldcraft Pure Tungsten 1/8" Electrodes - 10 Pack

Achieve superior results on your aluminum and magnesium welding projects with Miller Weldcraft WP018X7 Pure Tungsten Electrodes. Known in the industry as "Green Tungsten" due to their color code, these electrodes are the go-to consumable for welders utilizing Alternating Current (AC). Pure tungsten (AWS Class EWP) contains a minimum of 99.5% tungsten with no added oxides. This specific composition allows the electrode to ball up easily at the tip when heated, a desirable characteristic for AC TIG welding. The balled end provides a stable arc that wanders less, ensuring smooth, consistent beads and effective oxide cleaning on the surface of the base material.

Weldcraft, a brand synonymous with TIG welding quality, ensures that these electrodes meet strict manufacturing tolerances for diameter, length, and chemical composition. The 1/8-inch diameter is robust enough to handle the amperage required for medium-to-thick sections of aluminum, while the 7-inch length fits standard TIG torches perfectly. Because they contain no rare earth oxides like thorium or lanthanum, these electrodes are completely non-radioactive, offering peace of mind regarding long-term health and safety. They are particularly effective when used with older transformer-based power sources, though they also perform well with modern inverters set to appropriate AC balance settings.

It is important to note that Pure Tungsten is designed strictly for AC applications. Attempting to use these for DC welding is not recommended, as the tip will degrade rapidly and may contaminate the weld pool. However, for their specific purpose—welding aluminum and magnesium—they are unmatched in their ability to handle the thermal cycle of AC welding. This 10-pack ensures you stay stocked up for critical jobs, reducing downtime and maintaining the high standards of your welding output. Trust Weldcraft WP018X7 for a stable, clean, and controlled arc every time you strike up on aluminum.
