UPPER LIMIT SWITCH
The optional Upper Limit Switch may be used as a safety interlock in
automation to prevent the movement of material handling equipment
(indexing) when the horn is down. It also may be used to initiate the
movement of material handling equipment when the horn is up. The Upper
Limit Switch is located opposite the Pressure Switch.
The Upper Limit Switch is factory set and should be suitable for all
applications.
BOOSTER SELECTION
The first step in optimizing welding conditions is to select a booster which will
provide the necessary amplitude. For parts 2" (50.8mm) in diameter or
greater, start with a moderate amplitude booster such as a green. 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.
Six standard boosters, color coded or engraved for ease of identification, are
available either to increase or decrease the amplitude.
BOOSTERS
Color Part No. Gain Amplitude Effect
Black BHN16TBK 2.50 Increase
Silver BHN16TSI 2.00 Increase
Gold BHN16GD 1.50 Increase
Brown BHN16BR 1.25 Increase
Green BHN16GR 0 No Change
Purple BHN23PU 0.75 Decrease
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. See
note above.
