Review on 3mirrors ALUMINUM TIG Welding Tool with Tungsten Electrode Sharpener Grinder Head, 24 Guides 🔧 Including Dust Housing, Cut-Off Slot, Multi-Angle & Offsets, 5 Diamond Wheels, and 2 CNC Mandrels by Pat Haberman

I use an electric screwdriver to clamp the electrode and twist the tip while he sharpens the tip of the electrode. Fast and efficient. A transparent protective barrier prevents dust from grinding the electrode during tipping. The grinder dust cover can be easily removed to remove dust. Well done and a welcome improvement in terms of time saving and tip shaping.
