WHA3000P

Digital 700 W hot air station
with built in turbine

The WHA3000P will perform demanding repair tasks on circuit boards with complex fine pitch surface mounted components.

The advanced control technology coupled with user friendly operation, guarantees process control. The sophisticated automatic operation mode guarantees repeatability of the process and increases productivity and quality.

Extensive range accessories compliment the machine to promote flexibility.

LCD Display:

High contrast LCD characters clearly display the operating parameters.

Manual operation Operating parameters are selected by the operator.

Automatic mode A three-stage temperature/time profile controlling air temperature, air volume and process time can be stored in the machine memory to carry out repeatable repair operations. The WHP3000 hot plate can also be controlled in this mode. Up to 10 individual programs can be stored in the machines memory.

Both the WHA3000P and WHA3000V include a two-stage foot switch. Stage 1 activates the hot air flow, stage 2 activates the vacuum pickup.

WHA3000V

Digital 700 W hot air station for
operation with compressed air or inert gas

The WHA3000V will perform demanding repair tasks on circuit boards with complex fine pitch surface mounted components.

The advanced control technology coupled with user friendly operation, guarantees process control. The sophisticated automatic operation mode guarantees repeatability of the process and increases productivity and quality.

Extensive range accessories compliment the machine to promote flexibility.

A digital electronic control system guarantees precise temperature control and provides other functions, such as Auto off and stand by temperature. Set and actual temperatures are displayed digitally. Two heated zones can be selected The temperature of a specific point on the board under repair can be monitored and controlled by means of an optional external sensor. If used the temperature display will show the actual value of the temperature of the board at the point of contact, not the temperature of the hot plate elements. An RS232 interface connection from either of the WHA stations can be used to enable the hot plate to be used as an underside heater in a multilevel process sequence. If this option is required then we recommend that the WBH3000 board holder is used. The pre-heating plate is designed to sit between the side supports of the board holder.

WHA900

650-w Adjustable Air and Temperature Hot air station with built in turbine

With 650 watts of power, internal air adjustable from 5 L/min. to 50 L/min. and temperature variable from 100°F to 1,000°F, 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 Secret Is The Sensor

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.

• For reworking SMT components
• Compact design maximizes workspace efficiency
• Controlled output maintains set temp regardless of air flow setting
• Temperature and air flow are controlled independently
• Standby button allows you to power down to low settings when not in use
• Includes a rest support for the hand piece
• Nozzles sold separately - See Below

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.

Patented Nozzle Technology

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.
