Hardin-426 Metallurgical Smelting furnace The Hardin-426 is a compact electric furnace for melting scrap metal, reclaiming, alloying and refining metals and for Pouring metal in vacuum casting operations. The Hardin-426 is designed to be hand-held for easy pouring of the metal directly from the furnace or with included crucible tongs. This makes them ideal for use in casting, reclaiming, alloying and refining metals. The Hardin-426 is automatic and features a microprocessor PID control, PID auto-tuning function electronic controllers allow for extremely precise melting temperatures of metals such as high-karat gold, silver and copper. The electronic feature regulates the temperature by providing full power input to the furnace until a selected temperature is attained, and will hold the temperature to a +/- 1F. Maximum temperature 1200C/2192F. The Hardin-426 Metallurgical Smelting furnace incorporates a heat resistant safety grill that encompasses the heating chamber to protect against accidental direct contact with chamber. This Hardin-426 Metallurgical Smelting furnace is digitally controlled and automatically regulates the temperature by providing power input to the furnace until the pre-selected temperature is attained. Hardin-426 (1 - 3 kg Capacity) Power -650 WATT 110 Volt Melting Capacity: Gold - 3.1 kg / 100 Troy oz Silver - 2.6 kg / 83 Troy oz 25 minutes to 1200C/2192F. Includes Graphite Crucible (2kg)
