PURPOSE: To make the change of plating easy and contrive to increase its productivity, by arranging, in a freely removable manner, an auxiliary pot equipped on its lower part with an introducing port of a plating bath at the upper part of plating bath tank.
CONSTITUTION: A freely removable auxiliary pot 2 is arranged at the upper part of molten metal bath 1. Then, the bath 1 is introduced into the pot 2 from the introducing port 8 of the bath by opening a valve 7. Aimed alloy components are added into the pot 2 and alloy plating is carried out. Then, after all the alloy plating bath in the pot 2 is transferred to the auxiliary tank 10 when the plating is changed, the plating bath 1 is introduced into the pot 2 from the introducing port 8 by opening the valve 7 and different plating is carried out by the same method as abovementioned.
