3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder TIG Welding Tool Single Column Open Design w/Cut-Off Slot Multi-Angle &Offsets, Horizontal Hole ***Kind reminder: We are the original designers of tungsten electrode grinding controllers. We understand the products and welders, and our store has multiple functions of grinding sharpener. Accurate angle design and continuous updates have always been our requirement for ourselves. Please check 3 Mirrors brands before purchasing. Thank you.! Functional features 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. 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. 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. 3) Connect the mandrel with the Diamond wheel, and set it in your rotary tool. 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. 5) Always wear Eye Protection, Respiratory Protection, and Protective clothing when using the Angles Controller and when welding. There are also instructions in our package. *Upgrade Open single foot column support design(Tested by fall resistance), make installation more convenient and quick. Material: Made of 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 one column, which can be installed in one step, and the grinding wheel is aligned with the slit, and the position is accurate. This version of Tungsten Electrode Grinder Head Sharpener Comparison of the first generation(B07VWQ5553) features: They're almost identical, this model was designed with 1, A new Horizontal Hole so that can clean up tungsten electrodes that have picked up metal during welding easily. (This is also one of the improvements we made after collecting users' feedback) 2, Single-foot column support for quick installation. (Our model has been tested by fall resistance). PS: Our product is a Tungsten Electrode Grinder Head, you can buy a rotating tool for use yourself. We also have the full sets of tools in our store. Our package includes 1X Grinder Head, 4X Copper Screw Holes, 5X 25mm Diamond Wheels, 2X CNC Connecting Rod.
