Hot Air Technology

Equipment Overview

The control technology used in Weller hot air equipment guarantees precise and repeatable processes when soldering/desoldering SMD components. This process control is further enhanced by the application of Weller patented nozzle technology.

700-W Hot Air Stations

These stations use temperature and volume controlled hot air with Weller patented technology nozzles and the HAP3000 hot air pencil to solder and desolder the larger dual in line and quad pack components. There are three stations in the range giving users the option of digital control with an integral air supply, digital control with an external air or inert gas supply or analog control with an integral air supply. A wide range of hot air nozzles type ND and NQ with integral hot plates to heat the component body and types NR and DR without hot plates complete the range.

WHA3000P
Digitally controlled hot air station with an integral air supply and vacuum pick up at the nozzle. For demanding repair operations.

WHA3000V
Digitally controlled hot air station for use with a compressed air or inert gas supply and vacuum pick up at the nozzle.

WHA900
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.

100-W Hot Air Stations

This range of four stations is suited to reworking smaller SMD components. Like the 700 W stations the type D and type Q nozzles do have an integral hot plate but other types do not. These stations do not have a nozzle vacuum pick up therefore; it is necessary to use either manual or vacuum tweezers to remove the component.

Of the four stations in the range, two have internal electrically driven pumps, and two are operated from either a compressed air or inert gas supply.

WRS1002
A single channel digitally controlled repair station with an integral pump to provide variable volume air flow and fixed value vacuum. The station is supplied with a 100 watt hot air pencil, but all other Weller tools of compatible rating can be used.

WAD101
A single channel digitally controlled hot air station for use with compressed air or inert gas. The station is supplied with a 100 watt hot air pencil, but all other Weller tools of compatible rating, apart from the through hole desoldering pencil, can be used.
