CNC precision diamond re-grinding of spent electrodes tips, cleaned, labeled and packaged to meet your equipment specifications. Precision refurbished electrodes, lower welding costs and improve weld quality.

Arc-Zone Tungsten Grinding Pro Tip:

Frequently re-grinding worn electrode tips improve weld quality & lowers tungsten usage. Waiting until the tip is completely worn, requires grinding off more contaminated material, resulting in higher tungsten usage, costing you time & money.
