Safety Protection Systems
The IH-15A includes multiple safety protections for safe operation.
Overvoltage Protection
The system automatically shuts down when input voltage exceeds 245V, triggering an alarm and indicator light.
Overheat Protection
If the heat radiator temperature exceeds 55°C, the machine shuts down automatically.
Overcurrent & Malfunction Protection
The system shuts down if:
-
Internal components overheat
-
Signal interference occurs
-
Workpiece short circuits the coil
-
Induction coils touch each other
-
Input voltage is too low
Low Water Pressure Protection
If cooling water pressure drops below 29 PSI, the machine shuts down automatically.
Important Operating Notes
-
Always wear protective equipment and safety goggles during operation.
-
Crucibles must remain covered during operation.
-
Avoid prolonged no-load operation.
-
Cooling water must be clean and below 45°C.
-
Machine must be properly grounded at all times.
-
Thread tape must not be used during induction coil installation.
-
Single-turn coils smaller than 4 inches diameter should not be used.
