***Kind Reminder: We are the original designer of the tungsten electrode grinding controller, we know the products and welders, and we are always improving, so you can see that we have several grinders with different angles so far. Various counterfeit products are constantly appearing on the market. Watch out! They do not understand the tools and the design is inaccurate. Please look for our brand 3mirrors before buying. Thank you! 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. We produced the latest tungsten needle grinding tool to make grinding more simple and more convenient! Comparison of the first generation and the second generation Tungsten Electrode Grinder Head Sharpener features: Angle: The tip angle is more precise than the previous generation.Grinding angle problem: In addition to the angle of the needle tip, there is also a director of the grinding mark on the surface of the tip. This state is perfect when the tungsten needle is projected vertically on the grinding wheel, that is when the tungsten needle is parallel to the tangent line.Grinding wheel utilization: The first generation of four contacts are on the same ring; the second generation of dispersion distribution uses as much as possible of all corundum.Material: The first generation is plastic, (plastic is soft and easy to thread & melt at high temperatures, not recommended); The second generation is aluminum alloy, which is sturdy and durable.Installation problem: The new model does not need to adjust the position of the grinding wheel repeatedly. The middle cut-out design only leaves two columns, which can be installed in one step, and the grinding wheel is aligned with the slit, and the position is accurate. PS： Our product is a Tungsten Electrode Grinder Head, you can buy a rotating tool for use yourself. Our package includes 1X Grinder Head, 4X Copper Screw Holes, 5X 25mm Double side Diamond Wheels, 2X CNC Mandrels, 1x Instruction manual, 1X Packing Box INSTALLATION Illustration INSTALLATION: 1) Unscrew the top collar on Rotary Tool, and choose the correct size collet for the 1/8” mandrel. 2) Install the Angle Controller as shown in Picture-1. 3) Connect the mandrel with the Diamond wheel, and set it in your rotary tool. As Picture-2. 4) Adjust the height of the diamond wheel. Screw the collet when you are sure the Below of the Long window is on the same PLANE as the top face of the diamond wheel. As Picture-3. 5) Always wear Eye Protection, Respiratory Protection, and Protective clothing when using the Angles Controller and when welding. There are also instructions attached. Use this tungsten grinder head angle controller to maximize welding performance. Grinding wheels should be made of small granularity diamond or borazon. Grind longitudinally and concentrically so that the lines on the ground surface move in the same direction as the length of the tungsten electrode and the electrode has no flat spots. Compared with some other big grinders, their traces may be relatively straight, but the grinding angle is not accurate enough. The tungsten needle tip has a concave arc and can't be carried around, expensive ; Our grinder head is that the traces may be slightly curved(Quite slight, and it's an unavoidable problem with grinding on rotating objects), but the angle is accurate, the weight is light, easy to carry and use, and cost-effective. 4 Holes w/Screws ALUMINUM Tungsten Electrode Sharpener- Special Edition 24 Holes w/Dust Housing ALUMINUM Tungsten Electrode Sharpener- Healthy Edition 12 Holes Multi-Angle ALUMINUM Tungsten Electrode Sharpener- Starter Edition 3mirrors Healthy Tungsten Electrode Grinding Head with Dust Housing, TIG Weld... 3mirrors Angle Grinder Aluminum Tungsten Electrode Sharpener 4.5inch Diamond ... 3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder,TIG Welding Rotary Too...
