Description
This soldering station is designed to meet the present and future needs of the electronic production
industry. The soldering station is engineered to meet the stringent demands of hobbyist,
maintenance personnel, and production staff alike.
The electronic circuitry enables you to set soldering temperatures between 100 and 500 °C without
replacing the tip. The temperature is maintained to within ± 3 °C of the normal operating
temperature.
The highly insulated ceramic heating element and 100 W power result in rapid heat-up, instant
recovery, and superior heat transmission.
The ergonomic and slender handle with a comfortable rubber grip prevents operator fatigue. The
soldering iron is attached to the base unit using a non-burning silicone rubber cord.

Operating Temperature
The most common soldering alloys used in the electronics industry consist of 60 % tin and 40 % lead.
The operating temperature of this type of solder is detailed below and can vary from manufacturer to
manufacturer. However, to meet RoHS requirements, these solders are no longer allowed and are
replaced by lead-free solders that require a working temperature which is ± 30 °C (54 °F) higher.

lead-free solder
Melting point
215 °C (419 °F)
220 °C (428 °F)
Normal operation
270-320 °C (518-608 °F)
300-360 °C (572-680 °F)
Production line operation
320-380 °C (608-716 °F)
360-410 °C (680-770 °F)
A good joint is assured if the iron's operating temperature is set within the parameters suitable for the
type of solder being used. The solder will flow too slowly if the temperature is too low; if the temperature
is too high, the flux in the solder may burn which will give rise to billowing white smoke. In turn, this will
result in a dry joint or in permanent damage to the PCB.
