Professional hot air station for soldering and desoldering, featuring microprocessor control, adjustable temperature, and air flow regulation for precision electronics work.
Table of contents
Product Description
The Weller WAD 101 and WAD 101IG are high-performance hot air stations designed for professional soldering and desoldering tasks. The WAD 101 is a versatile hot air station, while the WAD 101IG is specifically designed for inert gas soldering using compatible tools. Both units utilize advanced microprocessor control to ensure optimal performance and automatic tool recognition.
Operation and Setup
Before initial operation, ensure the device is connected to a suitable power supply and that the mains switch is in the off position. Connect the soldering tool to the 7-pin socket on the front panel. For hot air operation, connect the compressed air supply (400 kPa) to the quick-action coupling. The desired temperature can be set using the UP/DOWN buttons, with the system providing digital feedback of both set and actual values. An integrated optical regulator monitor (red LED) indicates when the target temperature is reached.
Safety Guidelines
Always read the safety instructions before use. Do not direct the hot air tool at people or flammable objects. When using nitrogen, ensure the room is adequately ventilated. The device must be used only for its intended purpose; unauthorized modifications will void the manufacturer's liability.
Maintenance and Troubleshooting
To maintain temperature regulation accuracy, keep the transition between the heating element/sensor and the soldering tip clean and free of debris. During the first heating cycle, tin the soldering tip to remove oxidation. Always ensure the soldering tip is correctly seated. If the system fails to heat or displays errors, check the fuse and ensure all connections are secure. For advanced settings, such as offset, setback, or locking functions, an optional external input unit (WCB 1 or WCB 2) can be connected.

Common problems
System not heating up
Check the mains fuse and ensure the soldering tool is correctly connected to the 7-pin socket.
Inaccurate temperature regulation
Clean the transition area between the heating element/sensor and the soldering tip; ensure the tip is correctly seated.
No air flow
Check the compressed air supply pressure (400 kPa) and ensure the air hose is properly connected to the quick-action coupling.
