fast melting furnace electric induction furnace small forge furnace
Product Description
- The furnace is small, easy to operate, and will melt non-ferrous types of metals up to 1150 degrees C. (such as aluminium, lead, brass, bronze, gold and silver)
- It is ideal for the casting hobbyist, or for professional applications such as in the manufacture of jewellery or for alloy research projects.
- It is ideal for melting metal and then pouring the molten metal into moulds for the manufacturing of small castings, or heating applications requiring the heat treatment of metals.
- It simply plugs in to a normal 220V~240VAC domestic power point. No special power circuit is required. Power consumption when furnace power is active is 1.5KW.
- The size is: 165 * 225* 367mm and weighs 5.1 Kg. The complete package weighs 7.0Kg.
- Crucible weight is: 1 Kg capacity – 0.25Kg, 2 Kg capacity – 0.34Kg, 3 Kg capacity – 0.49kg
- The furnace controls are easy to use and allows precision setting of any desired temperature. It utilises a thermocouple which is used by the temperature controller to control the “ON” time, for the furnace to reach the desired temperature.
- Once the desired temperature is reached, it will maintain that temperature by the controller switching the power to the furnace “ON” or “OFF” as required, in order to maintain the desired temperature.
- The furnace comes supplied with a standard 1Kg crucible and suitable crucible tongs. Optional 2Kg and 3Kg crucibles are available if required.
- The tongs wrap around the crucible top recessed ring, allowing a safe method of removing the crucible for pouring.
- The furnace also comes supplied with heavy duty gloves and safety glasses.

How To Use It
- The “Green Switch” is used to turn “ON” control power and allows setting of the desired temperature using the temperature controller.
- The “Red Switch” allows power to go to the furnace and heating of the crucible begins.
- The desired temperature, “Green display” is set by adjusting the “Up” and “Down” arrows. The “Horizontal Arrow” is the curser and will allow you to set a particular digit, such as the “4” in this example, instead of progressing in an upcount mode all the way to 420. The curser points to a particular digit in order to change that digit.
- When you have set the particular digit to the correct setting, then you can either wait a few seconds or press the “Confirm” horseshoe symbol.
- Experiment with the controls with the “Red Switch” in the “OFF” position, until you are familiar with how to set the temperature. Then when ready, switch “ON” the “Red Switch” to start heating.
- The “Red” lamp will light when there is power going to the furnace, or will be off when the temperature controller is switching the furnace power off, or the “Red Switch” is in the “OFF” position.
- The “Red Display” shows the actual temperature as seen by the thermocouple.
Packaging & Shipping
Considerations when using the furnace:
1. Fit the supplied lid handle, found in the spares bag, to the lid. The other bits are for any ceramic spacers or insulators if replacement is needed. There is also a spare fuse.
2. Set the furnace on a stable flat surface such as a sturdy bench. Position the mould close to the furnace, so that the distance that you are carrying the hot crucible is minimal.
3. It is good practice to set a low temperature first, to allow the crucible to warm up slowly, such as 250*C. Let the furnace stay at that temperature for about five minutes. This also makes sure that the crucible and its contents are dry. Never use a moist crucible or add moist contents into the crucible.
4. It is also good practice to then set a medium temperature such as 650*C, let it settle, then set the final temperature such as 1140*C.
5. This implies that you are aware of the correct melting temperature of the metal that you are wanting to melt. The following table is to be used as a guide.
