10 pre-sharpened tungsten electrodes available in 0.8mm diameter, measure 50mm in length. The thin electrode increases precision by touching the exact spot of weld. Just prior to weld, the electrode pulls back into the handpiece by allowing for a clean and precise weld spot. Thorium-oxide free. Other diameters also available.  

<!—

NOTE: ONLY the 0.6mm electrode set comes with a diamond grinding wheel.
