<p>PROBLEM TO BE SOLVED: To prevent gas leakage from a solder reservoir.SOLUTION: A solder jet device 2 is provided with a return tube 36 whose top end 36a is joined to a bottom face of a partitioning plate 31 to enclose the entire lower portion of a communicating opening 33. Thus, even when gas is supplied to a solder reservoir 5, the gas cannot enter the inside of the return tube 36 and the inside of the return tube 36 is filled with solder S. Accordingly, the gas does not enter the lower portion of the communicating opening 33 and gas leakage from a contact section between an on-off valve 24 and the communicating opening 33 can be prevented.</p> |
