NOTE: Consult the
Applications Manual or call
our Applications Lab for
proper booster selection.
High gain boosters, such
as silver and black in
combination with high gain
horns can result in the horn
cracking or failing.
BOOSTER SELECTION
The first step in optimizing welding conditions is to select a booster which will
provide the necessary amplitude. For parts one inch (25.4mm) in diameter or
greater, start with a moderately high amplitude booster such as a gold. For
smaller parts, start with a green booster. Determine optimum amplitude by
welding a few parts, and repeat the procedure with boosters giving higher or
lower amplitude. If there appears to be little or no difference, use the booster
giving the highest amplitude.
Seven standard boosters, color coded or engraved for ease of identification,
are available either to increase or decrease the amplitude.
PRESSURE
During the welding process, sufficient pressure should be applied to the part
so that the mating surfaces contact each other. If the pressure is too low, the
process will run inefficiently causing unnecessarily long weld time cycles,
marking of the parts or poor welding. If the pressure is too high, the horn may
stop vibrating, the part(s) might fracture, or the power supply might overload.
