4. Features
• electronic temperature control
• password lock
• sensor and heater fail notification
• LCD display with digital temperature scale
• with on/off switch
• ceramic heating element with temperature sensor
• HEATER/SENSOR FAILED DETECTION: if the sensor circuit fails, the display reads "S--E" and heater
power is cut. If heater circuit fails the display will read "H--E" and heater power is cut.
• TEMPERATUE "LOCK-OUT" FEATURE: the temperature can be locked with a password which might be
useful in a production line.
• ESD SAFE AND SPIKE FREE CIRCUITRY: the "Zero Voltage" electronic switching design also protects
voltage and current sensitive components (CMOS devices, etc.) against overcurrent and transient
voltage spikes.
• LIGHTWEIGHT SOLDERING IRON: ergonomic mini handle that stays cool and prevents operator
fatigue.
• isolated power supply: high-quality 32Vac transformer designed for lead-free soldering
• available options:
spare soldering bits: 0.2mm (BITSSC1), 0.5mm (BITSSC2)

6. Description
• This soldering station is designed to meet the present and future needs of the electronic production
industry. The VTSSC71 is engineered to meet the stringent demands of hobbyists, maintenance
personnel and production people alike.
• A high-quality sensor and heat transfer technology ensure precise temperature regulation which is
essential for making consistent, reliable soldered connections.
• The aluminium alloy housing has several advantages: strong, good heat sink and very resistant to
electro-magnetic interference.
• The VTSSC71s' electronic circuitry enables the user to set soldering temperatures between 200 and
450°C (392 to 842°F) without having to replace the tip or the heating element. The temperature is
maintained to within ± 3°C (± 6°F) of the normal operating temperature by a thermocouple sensor
placed in the head of the heating element. The 100W power results in a rapid heat-up and fast
recovery.
• The revolutionary "zero voltage" switching design also protects voltage- and current-sensitive
components (CMOS devices, etc.) against the damaging current and transient voltage spikes
commonly produced by less efficient, mechanically switched stations. The heating elements are
galvanically isolated from the electrical supply by an isolating transformer that prevents the system
from using a max. tension higher than a (safe) 32VAC.
7. 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.
