After any group of elements is replaced ,it is necessary to decrease the voltage output to the correct minimum value from the power supply , otherwise, the elements will quickly overload and cause complete losses. The old elements from a group may be retained to use some other time. If possible , record voltage and current of every element replaced, heating elements, and mark the increased resistance value at terminal of element cold end in order to match the resistances in the future .

In order to compensate the change in voltage needed due to element resistance aging , a variable voltage power supply is necessary. heating elements. Usually 50%-100% voltage reservation s adjustment on a new element is required .
