● When turning the feeder hand wheel every 60 degrees, there is one cubicle material fall into the tipping bucket inside the furnace cover.

● Feeding tipping bucket is equipped with damping plate to prevent materials falls too quickly. When in use, gently shake the joystick (outside the furnace cover), you can control the speed and quantity of the material fall into the crucible

● Active shutter is installed on the observation window, preventing glass from burning broken and getting dirty by steam accumulation of metal.

● Shutter moves away shortly only when observing, controlled by the handle outside the furnace cover.

● Pre-sintering moulding crucible can be placed inside.
You can also make the crucible according to the inductor inner wall. The material of crucible is up to the melting metal.

● In front of the sensor, at the bottom of the furnace shell (where place the ingot mould), there is a circular pipe. On the pipe, there is a circular shelf to place ingot mould. Normally, ingot mould is placed on this shelf. When you need to cast the slender ingot, the ingot mould will be high, you can remove the shelf and put the ingot mould into the circular pipe, place it on the water-cooling cover. If you have some special needs, you can replace the water-cooling cover into a suitable water-cooling ingot mould room.

● Some complex recycling materials must be cut off and removed surface scale, non-metallic materials, etc.

● When feeding, you need to make sure the materials at the top of crucible is looser than the bottom. Use small piece of material to fill the gap. Place more regular shape material at the top to avoid scaffold bridging during the melting. In the direction of tapping hole can amass some granular materials.

● Feeding movements should be light to avoid crucible damage and slags in the metallic liquid.

● Pay attention to the heater of diffusion pump regularly. You can check if the heating wire is broken by measuring current.

● When vacuuming steam-containing gas, you should open the gas ballast valve on the 2 stage rotary pump, or it will contaminate the oil in 2 stage rotary pump and lower the max vacuum.
