1. Product Overview
The MINIWARE® AirGo 140 is the first PD-powered intelligent hot air gun developed by the e-Design team. Its compact, pen-shaped body weighs only 115g, making it highly portable for various applications such as on-site repairs, laboratory R&D, and daily electronic work.
Despite its small size, the AirGo 140 delivers a maximum heating power of 140W, with an adjustable air temperature range from 80°C to 450°C and 5 adjustable airflow levels. It can heat up from room temperature to 300°C in as little as 10 seconds. Users can customize settings to match the heat dissipation characteristics and sensitivity of different components.
This device is an effective hot-air solution for scenarios where traditional soldering irons or heating plates are challenging to use, such as BGA/QFN packages with bottom pads or double-sided board soldering. It features a front air intake and front air outlet design, a high-speed brushless fan for concentrated airflow, and dual power inputs (USB-C PD and DC 5525) for versatile power supply options. An intelligent sleep base with a Hall sensor automatically triggers sleep mode when the gun is placed on it, ensuring convenience and safety.
The AirGo 140 includes a user-friendly interface, mobile APP wireless control for real-time monitoring and adjustment, and multiple built-in protection mechanisms (intelligent power-off, high-temperature auto cooling, overvoltage, and overcurrent protection) to ensure stability and safety during long-term operation. It is constructed from high-temperature resistant engineering plastics and features a precise heating element, offering a lightweight yet durable design.

2.2 Power Supply Options
The AirGo 140 supports two power input methods:
- DC Power: DC5525 interface, voltage range 20-28V. Compatible with power adapters, industrial switching power supplies, battery packs, etc. Continuous output current should be ≥5A.
- PD Power: USB-C (PD) interface. Must support PD 3.0 or above, with 20V/5A (100W) or 28V/5A (140W) output. The 28V gear requires a PD 3.1 28V power supply paired with a USB-C cable that supports 48V 5A 240W EPR.
Important Note: Do not connect DC5525 and USB-C (PD) power supplies simultaneously, as this may damage the device.
The product can operate normally within 65-140W. For full 140W power and fastest heating, a 100-140W power supply is highly recommended. If the power supply is lower than 100W, the device will still function but may not reach the maximum temperature (450°C), and heating speed will be significantly slower.
3. Intended Use
The AirGo 140 hot air gun is suitable for a variety of precision heating tasks:
- Electronic Soldering & Desoldering: Ideal for surface-mount components such as BGA, QFP, and PLCC, especially for precision operations on small components within 1cm.
- Heat Shrink Tubing: For rapid and uniform heat shrinking of wire harness protective tubing.
- Shaping: Local heating, forming, and bending of plastic parts.
- Defrosting: Quick defrosting of frozen metal parts and pipes.
- Paint & Adhesive Removal: Local heating to remove paint, adhesives, and coatings.
- Preheating: Preheating circuit boards and components before soldering to reduce thermal shock.
4. Safety Instructions
Please read this manual carefully before use. Failure to follow these warnings may result in serious personal injury or equipment damage.
4.1 General Safety
- This appliance is intended for use by persons aged 16 years and above. Persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, may use this appliance only if they have been given supervision or instruction concerning its safe use and understand the hazards involved.
- Children should be supervised to ensure that they do not play with the appliance.

- Keep this device out of reach of children and individuals without relevant experience. If you hand the product to others, be sure to explain all safety precautions in advance.
4.2 Warnings ▲
- Burn Hazard: The air outlet reaches a maximum temperature of 450°C. Do not touch the air outlet or nozzle during use or immediately after power-off to avoid severe burns.
- Fire Risk: Do not direct hot air toward flammable materials such as paper, fabrics, foam plastic, gasoline, solvents, etc. Keep the work area clear of combustibles. Do not leave the device unattended during use; always turn off the power and unplug the cord before leaving.
- Power Safety: This product only supports a DC 20-28V power supply (USB-C PD charger or DC adapter). Do not use power sources outside this voltage range, as this may cause circuit burnout, fire, or electric shock hazards. Do not operate in damp environments or rain. Stop using the device immediately if the cable or other components are damaged.
- Power-Off Protection: Do not pull out the power plug directly when the heating element temperature exceeds 100°C. When shutting down the device, first stop heating via the control interface. The device will automatically enter cooling mode, and the fan will keep running to cool the heating element. Please cut off the power after the fan stops completely.

6.4 APP Wireless Control
The AirGo 140 supports wireless control via a mobile app. Users can monitor real-time device status and adjust temperature and airflow remotely. Scan the QR codes below for detailed operating instructions and to download the app.
7. Maintenance
7.1 Air Intake Maintenance
The front intake and outlet design draws ambient air during operation. To prevent fan clogging, always keep your work surface clean and free from fine particles, thread scraps, and solder residue.
7.2 Storage & Carrying
- Do not store the device until it has completely cooled down (the fan stops and the housing is not hot).
- The storage environment should be dry and dust-free.
- Avoid dropping or impacting the device. The air outlet is a precision component with a fragile structure. Dropping the device may deform the nozzle or cause internal damage.
- Protect the PD/DC interface area at the rear from heavy impact to ensure stable power supply.
8. Troubleshooting
If you encounter any issues, refer to the table below for possible causes and solutions. If the problem persists, contact customer support.
| Problem | Possible Causes | Solution |
|---|---|---|
| No screen display | Device in sleep mode | Pick up the device or give it a gentle shake; the screen will light up automatically. |
| Loose or damaged power cable | Check that the power connection is secure; reconnect power or replace the cable. | |
| Entered USB mode after PC connection | It is normal to see a removable disk without screen display when connected to a PC. | |
| A red bar flashes on the standby interface | Excessively high temperature at air outlet | Stop using; the red bar prompt will disappear automatically after full heat dissipation. |
| Low voltage icon appears in the lower-left corner of the standby interface | Insufficient power supply voltage | Enter the information interface to verify the voltage: DC ≥19V, PD ≥40W. Replace the qualified power supply if the standard is not met. |
| Accidental long press on Button B (device returns to standby during operation) | Button B is the exit button; press and hold it to exit the operating mode. Short press Button A to resume. | This is expected behavior. Avoid prolonged presses of Button B during operation if you wish to remain in operating mode. |
| Auto return to standby interface during normal operation | "Standby Time" triggered after placing on sleep base or "Idle Detection" function activated due to long inactivity. | Check whether "Standby Time" or "Idle Detection" settings are too short in the menu explanation (refer to Section 6.3 Menu Explanation). Adjust settings as needed. |
| Abnormal noise, burnt smell, temperature control failure, or fan stall | Internal malfunction | Stop using the device immediately, disconnect power, and contact after-sales service for repair. Do not disassemble the heating element or control board yourself. |
