1. Description

The WHA 3000P Hot Air Station is suitable for difficult repairs on circuit boards with FINEPITCH
components. A thorough design concept combines maximum process safety with ease of use and
technically advanced application solutions. A comprehensive range of accessories adds to the
possible uses of this repair workstation.

The hot air temperature at the hand-piece can be adjusted over the range of 50°C – 550°C
(150°F – 999°F). The air flow rate is generated via an internal turbine and can be adjusted between
the range of 5 l/min – 50 l/min. Hot air temperature and air flow rate are digitally controlled.

The vacuum necessary for lifting the component is integrated into the nozzle system and can be
activated to suit the operating mode chosen. Two operating modes are provided:
A The "Manual“ operating mode (MAN) can be used for manual work at the hot air temperature

and air flow rate set. Hot air and vacuum can be activated using the foot switch, manual
remote control console or directly on the control Panel.

B The "Automatic“ operating mode (AUTO) establishes a program with a 3-step time/

temperature profile, and can be used in conjunction with the WHP 3000 Pre-Heat Plate
available as an accessory.

The parameters for hot air temperature, air flow rate, temperature of the optional WHP 3000
Pre-Heat Plate and vacuum function can be adjusted separately and can be saved as a Rework
Profile for the specific application.

The repair station can also be complemented with the optional matched WBH 3000S Circuit Board
Holder for X-Y alignment and a stand with Z-axis guide for the hot air hand-piece.
