Parts & Consumables

Tungsten Electrode 1/8” x 7” Layzr Non-Radioactive.

Best for automated or robotic applications in alternating current (a/c) or direct current (d/c) due to low voltage tolerance (changes in tip to work piece distance) using inverter or transformer based constant current power sources. Good for low-alloyed steels, Non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Runs cooler than 2% Thoriated with longer life, low to medium amperage range. Best for low amperage starts.

1/8” X 7” Ground 2% Thoriated Tungsten Electrode

Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current-carrying capacity. This electrode operates far below its melting temperature, which results in a considerably lower rate of consumption and eliminates arc wandering for greater stability. Compared with other electrodes, Thoriated electrodes deposit less tungsten into the weld puddle, so they cause less weld contamination.

These electrodes are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.060 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium.

During manufacturing, thorium is evenly dispersed throughout the electrode, which helps the tungsten maintain its sharpened edge—the ideal electrode shape for welding thin steel—after grinding. Note: Thorium is radioactive; therefore, you must always follow the manufacturer’s warnings, instructions, and the Safety Data Sheet (SDS) for its use.
