SPARTUS D99 tungsten electrode grinder
repeatable precision in TIG welding
SPARTUS D99 is a bench-top tungsten electrode grinder built for TIG welders who expect a stable arc, consistent weld quality and full control over electrode preparation. Precise grinding of the electrode tip improves arc ignition, reduces welding defects and extends the life of tungsten electrodes.
Precise grinding of tungsten electrodes for TIG welding
In TIG welding, the way the electrode is prepared has a direct effect on arc stability, weld pool control and the appearance of the weld. Grinding by hand on an ordinary bench grinder often leads to an uneven angle, an off-centre grind and accidental overheating of the electrode. SPARTUS D99 eliminates these problems and allows precise, repeatable and controlled grinding of tungsten electrodes. Thanks to the stable bench-top design and the electrode guide, you get an even grind that matches the requirements of the specific TIG application.
Adjustable grinding angle 10-60°, matched to the process
The SPARTUS D99 grinder lets you set the grinding angle anywhere from 10° to 60°. This broad adjustment lets you match the electrode tip geometry to the material, the welding parameters and the arc profile you need. In practice, this means more control over the TIG process, both when welding thin parts with precision and in more demanding workshop or production applications.
Electrodes from 1.6 to 4.8 mm
SPARTUS D99 handles the most common tungsten electrode diameters used in TIG welding: 1.6 / 2.0 / 2.4 / 3.2 / 4.0 / 4.8mm. This makes the unit a good fit for workstations where different material thicknesses and different welding current ranges are used. As standard, the grinder comes with collets for all diameters and a standard grinding wheel.
Adjustable speed 1000-8000 rpm
The unit offers adjustable rotational speed in the 1000-8000 rpm range, so you can match the grinder to the electrode diameter, the type of wheel and the grinding result you want. The 150W motor ensures stable operation, and speed control makes precise grinding easier without overloading the electrode or the grinding wheel.
Repeatable results with the depth gauge
One of the most important advantages of the SPARTUS D99 is the depth gauge, which lets you set the correct electrode protrusion and keep the grind repeatable. This is especially important in series production, in shift work and wherever consistent electrode preparation matters. A repeatable grind means fewer random deviations, more predictable arc ignition and more control over the weld.
Longer wheel life and lower running costs
SPARTUS D99 is equipped with adjustment of the electrode position relative to the grinding wheel surface. This lets you use the wheel surface more evenly, which extends its life and reduces running costs. Workshops and production plants that grind electrodes regularly and need the unit to work efficiently for a long time will find this particularly practical.
Safer tungsten electrode grinding
The enclosed grinding chamber, the guard and the electrode guide make work safer than grinding on open bench grinders. The unit is designed for grinding the non-consumable electrodes used in the TIG process.
Stable bench-top design for workshop and production use
Its small size and low weight make the SPARTUS D99 a compact yet stable unit. The grinder works well as a permanent part of a TIG station, in the workshop, in service, in maintenance departments and in production. It is the right choice for users who want to replace random electrode grinding with a professional, repeatable and safer tungsten preparation process.
