Rio Tilt-Pour Automatic Melting Furnace

The Rio Tilt-Pour Automatic Melting Furnace is designed to provide a safe, easy-to-use

electrical method for melting gold, silver and other non-ferrous metals for casting and

ingot-pouring applications. It offers precise control of melting temperatures up to 2028ºF

(1120ºC) through its user-friendly, programmable controller with LED display. The insulated

lid holds in heat and keeps oxygen out for a cleaner melt. Operates on 110 volt; 50/60Hz.

Setting Up the Furnace

Unpack the shipping box and check to make sure your Automatic Melting Furnace includes

a crucible, a pair of crucible tongs, power cord and instruction manual.

Inspect the unit and accessories in case any damage has occurred during shipping (contact

Rio Grande immediately with any shipment issues). Make sure the inside of the heating chamber is free of any debris. If

there is a piece of wood or styrofoam between the control housing and heating chamber, remove it before operation.

Please Note: We recommend that you keep the carton and packaging material to reuse in the event the furnace must be

returned for repair or servicing.

If you haven’t done so already, choose an appropriate working site for the furnace. Make sure the top of your working surface

is composed of metal, ceramic, slate or any other surface that will not support a fire in case of a molten metal spill.

Warning! Allow at least 16 inches of space between the furnace and any surrounding combustible surfaces or items.

Heat emitted from the furnace requires at least this much open space to dissipate in order to avoid possible fire hazard.

Warning! Do not use this furnace in the same area with flammable or combustible materials as the furnace may ignite

these materials.

Notice The furnace should be used only in a well-ventilated area as some alloys release fumes that can create

health risks. Follow all local and federal regulations for proper ventilation procedures.

After setting up your furnace in a work area that meets the above safety criteria, check to-be sure the front power switch

is in the OFF position before plugging the furnace into a properly grounded 110–120 volt outlet.

Warning! To avoid electrical shock, the furnace must always be used with a properly grounded outlet and with the

correct voltage and electrical current handling capacity.

Notice In the event you need to replace the electrical system’s fuse, always use the correctly rated fuse. For the 3kg

model, use a 20-amp fuse; for the 1kg model, use a 15-amp fuse.

Rio Tilt-Pour Automatic Melting Furnace Operational Safety Your Rio Tilt-Pour Automatic Melting Furnace is designed to provide safe and efficient operation. Due to the extremely high heat and molten metal involved in this process, a high degree of caution and care are critical to ensure its safe use. Please note the following precautions before you proceed with operation of this furnace.

The ramp-up time for the 3kg model to reach 1950°F is around 20 minutes; this time will vary depending upon the temperature chosen and the amount and type of metal in the furnace. When the set-point temperature is achieved, the square green LED will come on.

Place the hot crucible in an inert environment (such as the crucible cooling jar sold below) to help slow graphite deterioration caused by exposure to oxygen. If you don’t have an inert environment, put the crucible inside the unit to cool.
