REMEMBER UNPLUG IN THE POWER CORD
◆ The station must be switched off and the power cord must be unplug in before
replacing the fuse in the P.C.B.
Caution: Soldering irons operate at high temperatures and can easily burn the
skins and/or objects. Do not touch the tip and heater at any time and to keep it a
safety distance from flammable materials while the unit is on or while being
cooling. Please allow a sufficient time for it to cool before changing tips or
servicing the unit!
PRODUCT DESCRIPTION
Both LF399D/LF-389D digital readout electronically temperature controlled soldering
stations have been designed to meet the present and future soldering needs of the
electronic production industry, hobbyist and students.
The LF-399D & LF-389D rated current have 220-240Vac, 50Hz or 100-120Vac, 60Hz
for option. Both incorporate electronic circuitry which enables the user to adjust the
temperature from 150℃(392℉) through 480℃(896℉) without changing the tip. The
temperature is maintained to within ±5℃(9℉) of its idling temperature through the
use of its PTC characteristic. Both engineer the heater failed detection, if the heater
circuit fails the display will read “H-E” and will automatically cut off the heater
power. Also the temperature can be locked by “password” code that is convenient for
production line management.
The electronic “ZERO VOLTAGE“ switching protects voltage and current sensitive
components, such as “CMOS” devices, against transient voltage spikes that can be
caused by switching the power or heater on/off or other environmental conditions.
The highly insulated ceramic heating element with heater insulation exceeds 100M
ohms. The specifically design heater brings the temperature up to approximately
565-650℃ (1050-1200℉) at full setting in about one minute. This results in very fast
heat-up, instant recovery and superior heat transmission.
The ergonomic and slender soldering iron designs with a comfortable rubber grip that
prevents operator fatigue. The soldering iron is attached to the base unit using a
non-burning silicone rubber cord.
The tip is grounded through the power unit to ensure leakage of less than 0.4milivolt,
and a wide selection of long-lasting, iron clad, nickel/chrome plated and pre-tinned
tips are available to meet all your soldering needs.
