Important Notes for Use  
Under no circumstances should the unit be powered on without a load (a load refers to the output port being connected to any load). The heating coil must be connected before powering on. Powering on without a load will cause the board to emit high-frequency noise, which may result in irreparable damage to the MOSFET. Only use a DC 48V 50A power supply; AC power is strictly prohibited. The red terminal on the power input is the positive terminal, and the black terminal is the negative terminal. Do not reverse the connections! During operation, do not block the intake of the cooling fan to ensure proper air cooling. Water cooling must be used during operation. It is recommended to use a cooling method where cold water enters and hot water is directly drained into the sewer.
The temperature displayed on the power meter is the temperature of the mainboard capacitor. If it exceeds 65 degrees Celsius, the machine must be allowed to rest.
If either the air cooling or water cooling system is not functioning, the machine must be stopped. Contact the manufacturer for resolution. When using a graphite crucible, a non-circulating water cooling method must be used, i.e., cold water enters and hot water is drained into the sewer, to prevent prolonged high water temperatures from affecting the service life (this water cooling method should also be used during prolonged high-power operation). Under no circumstances should the 12V auxiliary power supply be disconnected while the crucible is still inside the heating coil, as this will cause the water pump to stop working and the heating coil to be damaged by the crucible's temperature.
Operating Instructions
1. Ensure that the main power switch is turned off! Use a 17mm wrench to securely fasten the heating coil to the heating coil connector;
2. Connect the external water pipe to the pre-prepared cold water supply; if using recirculating water, ensure there is at least 20L of water;
2. Connect the external water pipe to the pre-prepared cold water; if using recirculating water, ensure there is at least 20 liters of water;
3. Insert the DC12V power supply into the DC12V input port, connect the 12V power supply, and observe the fan and water pump operating, the power meter displaying voltage, and the alarm indicator light illuminating:
4. Connect the DC48V power supply according to the wiring diagram, plug in the AC220V power supply, and wait approximately ten seconds for the power supply to stabilize;
5. Flip the main power switch and observe that the power display voltage is approximately 48V;
6. Press the middle “M” button on the right side of the power meter to reset it.
7. Press the reset button. If the red alarm indicator light turns off, the system is functioning normally. If the red alarm light remains on, check whether the water cooling system is operating properly or if the DC 48V power supply is outputting normally. If both of the above are functioning normally, press the reset button quickly again until the red alarm light turns off.
8. Press the heating button to start the heating process. The green heating indicator light will illuminate, and the power meter will display the current heating power in real time.
9. After use, press the reset button to turn off the heating. The green heating indicator light will turn off. Turn off the power switch, remove the heated object from the heating coil (if there is a crucible, remove it first), and wait for the water pump fan to continue running for more than 30 seconds before turning off the 12V power supply.
4. Common Solutions for Red Alarm Lights
1. Water cooling failure: Ensure that water is flowing through the water pipes. If there is no water flow, the water cooling machine will stop heating.
2. Power meter not reset: Press the “M” button before each power-on.
3. 48V power output is abnormal with no voltage. Check if the 220V power supply is normal and if the green indicator light on the power supply is lit. Alternatively, inspect the wiring between the machine and the power supply to ensure it is secure. 4. Machine overload. The factory-set maximum alarm power is 3200W. If the red light illuminates due to power overload, heating must not continue, indicating that this workpiece is unsuitable for heating with this machine.
