AT-90DH Digital Soldering Station

Technical Advantages

The AT-90DH digital soldering requires just 10 seconds to go from room temperature to 350ºC. Variable temperature, silver alloy conductive materials, automatic sleeping support.


90W Digital Soldering Station with LCD Display and Fast Heat Up

  • HD LCD, backlight LCD, visualized process control and easy to operate.
  • Silver alloy as heat conducting material, heat exchange mode, and very fast temperature returning.
  • Temperature rises to 350ºC in 10 seconds after starting up.
  • Immediate temperature access function and quick switch of service temperature.
  • Auto sleep and password locking.
  • Separate design between soldering iron and heating core, thus saving on use-cost.
  • Handy handgrip and comfort to use.
  • Fault display warning function.

Heater's Revolution

Being one of the best selling soldering stations, AT-90DH Soldering Station utilizes the new 3nd generation of heater. See whats new below.

1. Ordinary heater:
Output AC: 24V 50Hz
2. Electro-magnetic high frequency heater:
Output AC: 28V 200KHz
3. 3nd generation heater:
Output AC: 24V 50Hz

Why choose this 3rd generation heater?

Because it absorbs the merits of above two kinds of heaters and filtering their defects.
Technically, the heating theory is as same as the first kind. But heat conduction material is replaced by silver, as a result, heat loss is controlled in a minimum extent. Meanwhile, comparing with Electro-magnetic heater, the latter has no electro-magnetic interference.

The iron tip that comes with the new heater has smaller size, resulting of a lower cost for replacement.
