The LF-3500 incorporates electronic circuitry which enables the user to alter tip
temperature from 100 to480
℃
without changing tips or heating elements. Also, with
digital display readout and pressing keys on the front panel get clear vision and
comfortable setting. The temperature is maintained /-
3℃
of its operating
temperature by a thermocouple sensor placed in the head of the heating element,
allowing the tip to rest against the sensor. The 150W power results in both a rapid
heat-up and super fast recovery.
The revolutionary “Zero Voltage” electronic switching design also protects voltage
and current sensitive components (CMOS devices. etc.) against damaging current and
transient voltage spikes commonly produced by less efficient, mechanically switched
stations. The power unit is isolated from the A.C. line by a transformer and allows
only 36Vac to drive the heating element. The temperature “Lock-out” feature by
“password” is convenient for production management. The many features of the
product make it the ideal tool for service and repair technicians as well as production
line soldering operations. This unit is developed to meet the present and future
lead-free soldering needs of the electronic production industry and is ideal for use at
any AC outlet.
