The CHUERA-309D combines temperature monitoring, audible warnings and setting control in a digital lead-free soldering station. Its large LCD keeps the real-time temperature and selected setting visible together, while the temperature alarm draws attention to unusually high or low readings.

The control unit connects to a separate soldering handpiece and iron holder. Temperature adjustment and calibration are handled through the front-panel buttons, with a plug-in heating core providing a serviceable heating assembly.

Read the Temperature, Hear the Warning

The LCD presents two temperature values at the same time: the station’s real-time reading and the set temperature. During warm-up or soldering, the operator can compare the reported temperature with the target without changing screens.

The large display also keeps the operating status visible from the front of the station. This is useful when attention moves between the soldering point and the controls.

An integrated buzzer provides an alert when the station detects an abnormally high or low temperature. The audible reminder adds another way to notice a temperature condition that may otherwise be missed while working. It complements the display rather than requiring the operator to watch the screen continuously.

Retain the Chosen Setting During Repeated Work

The working temperature is adjustable from 50 to 550°C using the front-panel controls. A temperature can be selected for the solder, tip profile and connection being worked on.

Once the required setting has been established, the temperature lock helps prevent unintended changes. This keeps a selected working temperature in place during repeated soldering operations.

The lock is particularly relevant when the same task is carried out across a series of components or assemblies. It protects the setting without removing the ability to check the temperature on the LCD.

Front-Positioned Sensing for Responsive Heating

The CHUERA-309D uses a front-positioned temperature sensor to support temperature control and rapid recovery. As the soldering tip transfers heat into a joint, the sensing arrangement helps the station respond to changes in temperature.

Maximum instantaneous power is specified at 90 W. This is the stated peak-power figure, not a separately specified continuous power rating.

No-load temperature stability is ±2°C. This value applies when the iron is not transferring heat into a workpiece. During soldering, temperature response also depends on the tip profile, contact area and heat absorbed by the joint.

Digital Correction and Automatic Sleep

Digital temperature calibration allows a correction to be entered when a reference measurement identifies an offset. The calibration function is separate from normal temperature adjustment: one corrects an identified deviation, while the other selects the working temperature.

An automatic sleep function is included to help reduce energy use during periods of non-use. It supports work routines that include pauses for component positioning, inspection or preparation between soldering operations.

Temperature calibration, sleep and temperature locking serve different purposes. Together, they provide control over the working setting, temperature correction and idle operation without adding separate external controls.

A Replaceable Heater with Clearly Identified Components

The plug-in heating core is designed for convenient replacement. It is listed separately from the handpiece and soldering tips, allowing the required service component to be identified by its model reference.

LT 309 Soldering Handle

The LT 309 is the optional handle listed for the CHUERA-309D. It is shown as a handpiece-and-cable assembly with a connector for attachment to the station. The illustrated handpiece has a cushioned grip and rests in a separate holder between operations.

CH 90 Heating Core

The CH 90 is the listed replacement heating core. Its plug-in construction simplifies servicing of the heating assembly without treating the tip and heating core as one integrated cartridge.

200 Series Soldering Tips

The optional 200 Series range includes several tip profiles. Pointed, flat and angled forms provide different contact shapes for component leads, terminals and other accessible solder joints.

The tip profile should be selected for the working space and contact area. The accessory illustrations show available options; they do not establish that every pictured component is included with each station.

Arrange the Display and Iron Rest Separately

The control unit measures 195 × 130 × 100 mm, with the LCD, adjustment buttons, power switch and handpiece connection positioned at the front.

The separate holder can be placed beside the station where the iron is comfortable to reach. Its integrated sponge tray keeps the resting position and tip-cleaning area together.

This arrangement lets the controller remain in view while the holder is positioned closer to the working hand. Additional space should be allowed for the holder and movement of the handpiece cable.

FAQ

What do the two temperature values on the LCD represent?

One is the real-time temperature reported by the station, and the other is the selected working temperature. Both remain visible together, allowing the operator to compare the reading with the target.

Does the temperature alarm provide an audible warning?

Yes. The CHUERA-309D includes a buzzer that provides a reminder when an abnormally high or low temperature is detected.

Can the working temperature be locked?

Yes. The temperature lock helps prevent unintended changes to the selected setting during repeated soldering work.

Which replacement components are listed for this station?

The listed optional components are the LT 309 handle, CH 90 heating core and 200 Series soldering tips. The heating core uses a plug-in design for convenient replacement.

Is the ±2°C specification the temperature accuracy at every solder joint?

No. It describes temperature stability under no-load conditions. Heat transfer into a joint affects the tip’s temperature response during soldering.

Does the CHUERA-309D include automatic sleep?

Yes. Automatic sleep is included to help reduce energy use during idle periods. A specific sleep delay is not stated in the supplied specifications.

What power supply is required?

The specified operating supply is AC 220 V at 50 Hz. The supply should match the rating marked on the individual station.
