• Shape: cylindrical heating tube

• Material: stainless steel

• Voltage: usually 110V or 220V

• Power: often 200W–600W (depends on machine size)

• Lead wires: high-temperature fiberglass insulated

Common problems & signs:

• Weak or uneven sealing → heater losing power

• No heat at all → heater burned out or wire break

• Overheating → faulty thermostat or temp controller

If you want, I can help you:

• choose the correct replacement

• calculate wattage & voltage

• troubleshoot why your band sealer isn’t heating

• or find equivalent models used in FR-900 / FR-770 / DBF series machines

Just tell me the model of your band sealer or the heater’s size & rating.
