We had a system which started the solder pump prior to all solder in the pot
being molten. As a result the lower portion of the pot melted and then when
finally the top surface of the solder melted, it allowed the pressure from
the pump to be relieved. The result was the same as you are experiencing.
The solution was to change the timing when the pump turned on.

        Subject:        [TN] Solder splatter on wave solder machine

        Hi all,

        Our solder on the Technical Devices wave solder machine is set to
come on
        at early morning so that by the time my operators come in for work,
        solder pot will be at its set temperature.  My operators have
noticed
        solder splatters along the conveyor rails and vacinity around the
solder
        pot.  I think it happens during heating of the solder pot.  Do you
have
        any ideas as to what would cause the solder pot to splatter during
        heating?

        Your input is greatly appreciated
