Stop and Go Hot Air Tool Holder
The tool holder AKT30 is a stable support for the hot air pencil. When the pencil is replaced in the support the airflow rate is automatically switched to the standby mode, at a minimal flow rate, sufficient to maintain the nozzle at its operating temperature. Removal of the pencil will switch the airflow back to its selected flow rate.

Protection class 1 (control unit and hot air iron hard grounded)
The WHA3000P
will perform demanding repair tasks on circuit boards with complex fine pitch surface mounted components. The advanced control technology coupled with userfriendly 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.
ESD safe The hot air is delivered through an ion trap to remove any charge and the tool handle and tubing are manufactured from static dissipative materials.
Both the WHA3000P and WHA3000V include a two stage foot switch. Stage 1 activates the hot air flow, stage 2 activates the vacuum pickup.
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.
External sensor A machine-mounted socket is fitted to receive a type K thermocouple; this would be used to record the temperature of a specific position on the circuit board and allow precise process monitoring.
Internal pump A powerful maintenance free rotary pump generates the machine airflow, variable up to 50 l/min.
The ergonomic and powerful hot air pencil
(700 W) together with the extensive range of patented technology nozzles (see pages 11-13) make this tool very versatile. Hot air nozzles are secured to the tool by a clamping screw. A vacuum plate will lift the component from the board after reflow. A nozzle removal tool supplied with the machine enables rapid removal and replacement of nozzles, even when hot.
