🔥 IEEE 837 / ASTM B33 (#65 to #250 Powder Charge Cartridges, Permanent Welds)

Exothermic Welding (Cadweld) Calculator

Size exothermic molecular weld metal cartridges and graphite molds (ERICO Cadweld / Harger Ultraweld) for grounding grid connections under IEEE 837 & NEC 250: calculate weld metal powder charge gram weights (#65 to #250 powder shots for cable-to-ground rod, cable-to-rebar, and cable-to-steel column connections), handle clamps, and high-spec electrical profits.
