The D90 grinder enables precise and efficient sharpening of the tungsten electrode tip according to the technological requirements.
Electrodes sharpened with D90 grinder present, among other things, an extended service life and allow easier arc welding. The grinder enables sharpening of electrodes with diameters of 1.6 to 4.8 mm at an angle from 20° to 60°.
Built-in depth checker allows to select the right depth of sharpening and ensures repeatability of the process. Ability to displacement the electrode with regard to the surface of the grinding wheel significantly increases the life of the blade - which results in lower operating costs.
Standard grinder is equipped with a clamping sleeve for electrodes with a diameter of 2.4mm and a basic grinding wheel. It is possible to purchase clamping sleeves for other diameters and diamond wheels.
