Sherman GRR-750 tungsten electrode sharpener

The Sherman GRR-750 sharpener is designed for preparing tungsten electrode tips. This is especially useful when welding highly alloyed materials, titanium, copper, and for all work where high welding quality is required (e.g., in aviation, pipelines, and the medical industry).

Thanks to the repeatability of the electrode tip shape, it is possible to achieve the highest-quality welds, improve arc stability, and reduce contamination of the weld pool.

Main parameters and advantages:

• The sharpener allows you to set and continuously maintain the electrode angle, which directly translates into control of focus and arc stability as well as penetration depth. Perfect for welding that requires a narrow or wide penetration profile.
• Thanks to its precise mechanism, the sharpener reduces electrode shortening during grinding, significantly extending the service life of expensive tungsten electrodes.
• The sharpener effectively reduces tungsten dust, protecting the operator.
• Precision guides support standard electrode diameters (1,0 / 1,6 / 2,0 / 2,4 / 3,2 / 4,0 mm), ensuring versatility.

Main features:

• Easy operation thanks to pre-set grinding angles and diameters
• Ability to select grinding angles of 15°, 18°, 22,5° and 30°
• A convenient device, perfectly suited for workshop use
• Integrated 5-speed control using a knob
• Easy replacement of the grinding disc
