PrimeWeld 2% LA57 Tungsten Electrode (Blue,WL20) TIG Welding Electrode
Most commonly used non-radioactive tungsten. Offers long electrode life under heavy or pulsing amperage loads. It has the ability to resist thermal shock which provides the user with excellent ignition with a lower burn off rate.
The blue LA57 electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications and are a popular general use electrode. Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corroding steels.
