Micron
T 2444A Soldering Station
2
Operating Instructions:
1 Place the soldering iron into the stand provided.
2 Plug in the power cable and slide the switch to ‘on’ position then LED lamp will be
on. The extractor fan will start automatically.
3 Set the temperature by rotating temperature control knob on the front panel to
the temperature desired.
4 Always keep the sponge wet.
5 Set the temperature control knob to the minimum when temporarily not using the
soldering station, thereby extending the life of heater and tip.
Working Temperature:
A low iron temperature will slow the flow of solder. A high temperature will burn
the flux in the solder, which in turn will emit a heavy white smoke, that can result in
a dry joint or damage to the PCB. When the tip working temperature is within the
correct parameters suited to the particular solder being used, a good joint is assured.
The most common solder alloy used in the electronics industry is 60% tin, 40% lead
(60/40).The tip working temperature of solder is detailed below and can vary slightly
from manufacturer to manufacturer.
Melting point: ............................................................................................................ 215°C
Normal Operation ..................................................................................................... 320°C
Production Line Operation ......................................................................................... 380°C
Desoldering Operation for Small Joint ........................................................................ 320°C
Desoldering Operation for Larger Joint ....................................................................... 400°C
NOTE: Lead-free solder alloys require a working temperature of 30°C higher than the
previous generation of electrical soldering.
Caution: Temperatures above 400°C should not be used for normal soldering
purposes; however temperatures above 400°C may be used for short periods when
required.
Possible causes of tip not tinning
-
1. Tip temperature higher than 400°C
2. Working surface is not well tinned during idling periods
3. Lack of flux in soldering, wicking, repairing and touch-up etc. operations.
4. Wiping tip on high sulphur content sponge, dirty or dry sponge and/or rags.
5. Contacting with organics, plastic resins, silicone grease, and other chemicals.
6. Impurities in solder and/or low tin content.
