Seeking advice on new iron/handle for old soldering station (thermocouple sensor type)

First post here, so hopefully this is an appropriate post for this section
:slight_smile:


I have an old soldering station (Micron - pre 1990s) that needs a new iron (lack of tip availability, corrosion of original sleeve). The station belonged to my grandfather and is something of a sentimental piece, so I’d love to get it back into action. Will be soldering mostly through hole, and some SMD (SOT23).

The heater element measures 12 ohms (heater) and 1 ohm (thermocouple sensor). Supply from station is 24V AC, and the old handle states 48 watts.

I’d love some suggestions on what would be a good compatible replacement handle with compatible thermocouple sensor-based heater, and the resistances of my original iron.

What would be a good bang for buck iron, with good tip availability that would fit my station? Can I get something decent for 50 bucks or less? I’ve looked around, but am a bit lost at this point.

Any advice would be greatly appreciated!

Cheers
Nick

The old Dick Smith Electronics (DSE) T-2000 looked very similar.
They operate on 24v (not sure about your AC part though) and are 48w as far as I know.
Some parts are still available but you would need to search.(expensive to boot) but they do last a long time.
Stlll use one here.
There are also these 907 style 24v DC.

The old handle was not original to your unit. Someone pulled the old switcheroo on you...

Altronics Micron T 2440 is an 60 Watt Soldering Iron . These guys have been around for a while I would call them directly. stick with the OEM.

The posted link was incorrect it was supposed to be of a soldering station not an soldering iron, anyway 60 watts 24 VAC ceramic heating element are very common.
Can you take a photo of your soldering iron you plugged into your soldering station .
Anything else you'd have to go into the PCB board find the operational amplifier is connected through the thermistor for your temperature regulation.
