Dynaflux Chem Sharp™ Tungsten Sharpener/Holder Kit Chem Sharp is a safe alternative to tungsten grinding. Chemically mills a perfect point on pure, thoriated, ceriated, and lanthanated tungsten. Average time to re-point tungsten is approximately one minute at the work station.
With 1% and 2% thoriated tungsten electrodes, arc starting is easier and wider current ranges can be used. This is due to the addition of thoria. Thoria will not become molten, and it reduces the tendency of the electrode to stick or freeze to the work.
