When it comes to the safe removal of larger, high lead-count SMD
components and the capability to handle numerous other hot air
applications, the WHA900 gets it done like no other station. It’s
the only unit in its class to have features like these…
• Closed-loop temperature feedback control that maintains the
temperature at the nozzle, independent of the airflow rate
• User-selected temperature and air flow setback
• Temperature offset control that fine-tunes the hot air temperature

With 650 watts of power, internal air adjustable from 5 L/min. to 50 L/min. and temperature
variable from 100ºF to 1,000ºF, the new Weller
®
WHA900 Hot Air Station is a solid performer.
But what really puts the WHA900 ahead is its closed-loop temperature feedback control that
maintains the temperature at the nozzle, independent of the airflow rate.
The WHA900 has a sensor located at the nozzle that continuously samples the temperature and
instantly adjusts the heat output to maintain the temperature you’ve pre-selected. So you don’t
have to readjust the temperature every time you change the airflow rate. Set it once and forget
it. So your rework production increases and your reject rate goes down.
That’s the Weller Advantage.
The WHA900 is the
only unit in its class that
has a temperature and air flow
setback than can be pre-selected
by the user. Plus it’s the only unit that
features a temperature offset control that
fine-tunes the hot air temperature right at the
tip when an ultra-precise temperature is required
for thermocoupled component removal.
Air from internal pump is
infinitely adjustable from
5 L/min. to 50 L/min.
Hot air temperature
is infinitely adjustable
from 100ºF to 1,000ºF
(50ºC to 550ºC)

Whether you are replacing SMD components with external solder
connections or other types of components such as SMT bases or PGAs,
Weller provides you with the solution to your rework challenges.
When removing defective SMD components, the need to prevent damage to
the circuit board and adjacent components is critical. In order to accomplish
this, Weller systems use conducted heat from an integral hot plate to heat
the defective component to a temperature just below the solder melting
point. Weller nozzles then direct hot air precisely
onto the legs of the component to melt the solder
joint, allowing removal of the component.
This combination of conducted heat and
precision-placed hot air is especially
suitable for lead free solders with
higher melting points.
