Package Includes 1x Electric Grinder 1x Storage Box 1x Hexagon Screwdriver 1x Acrylic Dust Cover 2x Carbon Brushes YesWelder Pro Tip: Frequently re-grinding worn electrode tips improves weld quality & lowers tungsten usage. Waiting until the tip is completely eroded or contaminated, requires grinding off more tungsten material, resulting in higher tungsten usage, costing you time & money.
