Preparations before maintenance of induction melting furnace:

1, Induction melting furnace with problem (single power supply)

(1) Turn off the power supply and prevent erroneous startup through the main switch

(2) Activate the grounding switch of the induction melting furnace

(3) Place a warning sign for "maintenance work"

2, Induction melting furnace with problems (dual power)

(1) Turn on the separation switch of the inverter unit or capacitor unit on the induction melting furnace

(2) Activate the grounding switch in the furnace shell of the induction melting furnace and prevent it from starting incorrectly

(3) Place a warning sign for "maintenance work"

3. The induction melting furnace in operation can now continue to operate: before starting relevant maintenance, inspection and repair work

Analyzing the maintenance, inspection or repair of induction melting furnaces is also important for use

4. Power supply unit or inverter unit (single power supply)

(1) Turn off the power supply and prevent erroneous startup through the main switch

(2) Activate the grounding switch of the induction melting furnace

(3) Place a warning sign for "maintenance work"

5. Power supply unit or inverter unit (dual power)

(1) Turn off the power supply and prevent erroneous startup through the main switch

(2) Turn on the separation switch of the inverter unit or capacitor unit on the induction melting furnace

(3) Activate the grounding switch in the shell of the induction melting furnace and prevent it from being started incorrectly

(4) Activate the grounding switch of the induction melting furnace

(5) Place a warning sign of "maintenance work"
