3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder TIG Welding Upgrade Variable Speed Rotary Tool 24 Guides w/Dust Cover, Diamond Wheels, Mandrels 3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder TIG Welding Upgrade Variable Speed Rotary Tool 24 Guides w/Safety Housing & Cut-Off Slot, Multi-Angle& Offsets, 5 Pro Double Sided Diamond Grind Wheels(35m), 2 CNC Mandrels The Features of the most powerful combination Kit- 24 Guides Tungsten Electrode Sharpener Grinder TIG Welding Tool w/ Upgrade Rotary Tool: Dust cover design to get free health and convenience. Tungsten is heavy metal, and most tungsten needles contain about 2% of weak radioactive elements, such as tantalum tungsten needles, tantalum tungsten needles, and pure tungsten needles. As the pictures show.The new design has 6 sizes, each size can ground 4 kinds of tip Angle, a total of 24 Angle holes, suitable for a wider range of tungsten needle sizes.Due to a more accurate Angle control design, the cutting point is offset to the center of the grinding bevel rather than the top. INSTALLATION STEPS : 1: Put on the 2 O-rings to the aluminum main body to ensure the Dust cover can be fixed and prevent dust leakage; 2. Install the mandrel to a Diamond wheel; 3. Screw the aluminum main body on Rotary Tool; 4. Set the grinding wheel and mandrel in the collet of your rotary tool; 5. Adjust the height of the Diamond wheel, Make sure the grinding wheel is parallel to the edge of the control head; 6. Push the transparent Dust cover on the control head; 7. If the dust cover is too tight to push, You could apply some oil (Whatever Engine oil, grease or Dishwashing liquid) on the O-ring so the cover will be easy to install; 8. Start grinding different angles of tungsten needle, according to your needs; 9. After grinding, Centralized processing of the tungsten power, avoid trouble, convenience and healthy. Tungsten electrodes of varying diameters are typically used in conventional welding procedures practiced in a wide variety of industries. During such procedures, an arc is established between the metal to be welded and the end, or point, of each electrode. The electrode point becomes worn or damaged over time, resulting in inadequate or interrupted current transmission. As the quality and efficiency of welds are highly dependent upon the condition of the electrode point, it is important that the point be dressed, or reshaped and sharpened, as needed during welding operations. After much research and development as well as a lot of users' feedback, Here is it. 3mirrors Tungsten Electrode Sharpener Grinder Angle Controller TIG WIG Welding Tool Grinding for 040 1/16 5/64 3/32 1/8 5/32 every 4 tips 30° 36° 45° 60° (The problem of the 2 sets of hole direction and hole spacing has been improved) Widely applicable sizes. The Lastest design is available for 6 sizes of tungsten needles: 040", 1/16", 5/64", 3/32", 1/8", 5/32" (1mm, 1.6mm, 2mm, 2.4mm, 3.2mm, 4mm); Each size can grind 4 tip angles: 15° 18° 22.5° 30° (30° 36° 45° 60°). Multi-Angle hole alignment, tungsten needle insertion Angle and grinding process more refined. Package included: 1x Aluminum Tungsten Electrode Sharpener Grinder,1x Upgrade Red Variable Speed Rotary Tool,1x dust cover (Clear Housing),5x 35mm Diamond Wheels (Pro),2x CNC Connecting Rods, 2x O-rings, 1x Vertical grinding block,1x small storage bag, 1x instructions. IMPORTANT: If the grinding wheel cannot be aligned with the cut during the installation process, or the grinding wheel does not reach the expected position, it may be that the chuck you are using is too high and exceeds the height of the mandrel installation. At this time, please replace a chuck with a height not exceeding 34mm, so that the grinding wheel can be adjusted in a proper position. Regarding the wired rotary tool, this newly upgraded 6-speed controllable rotary tool /electric grinder, designed with silicone surface non-slip handle and heat dissipation holes, has better quality and premium performance, Stable rotation speed, the longer service life of inner parts.
