PROBLEM TO BE SOLVED: To make it possible, when soldering or solder plating a work for a multiproduct with a small lot, to perform fine-tuned control of an arm to do an operation in a condition best suited to the work, the operation of fast immersing the work to the surface of molten solder or pulling it up from there to release it. SOLUTION: When the assumption is made that one side of a rectangular work virtual frame circumscribed on a work held at the tip of an arm for fast immersing it to the surface of molten solder is A, the side of the work virtual frame opposed to A is B, the fast immersing the work to the surface of the molten solder is "down", and the pulling up the work to release it from the surface of the molten solder is "up", the molten soldering equipment or molten solder plating equipment performs an up-and-down operation of the work in the sequence of (1) A "down", (2) B "down", (3) A "up", and (4) B "up".
