PUK Electrodes (Pkg of 10)

10 pre-sharpened tungsten electrodes in 1.0mm, 0.80mm or 0.60 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.
