Caution; Description; Commissioning; Note On Use - Weller LR 82 Operating Instructions Manual

English
Thank you for placing your trust in our company by purchasing
the Weller soldering iron LR 82. Production was based on strin-
gent quality requirements which guarantee the perfect operation
of the device.

1. Caution!

Please read these Operating Instructions and the attached Safety
Information carefully prior to initial operation. Failure to observe
the safety regulations results in a risk to life and limb.
The manufacturer shall not be liable for damage resulting from
misuse of the machine or unauthorised alterations.
Safety Informations
● Always place the soldering iron in the original holder.
● Remove all inflammable objects from the proximity of the
hot soldering tool.
● Use suitable protective clothing. Risk of burns from liquid
solder.
● Never leave the hot soldering iron unsupervised.
● Never work on voltage-carrying parts.

2. Description

The LR 82 soldering iron is of use wherever large amounts of
energy with precise temperature control are required.
The HT long life tips are heated from the inside and are fixed to
the 80 Watt low voltage element with a bayonet connector that
prevents the tip turning. The 80 Watt heater power combined
with the optimal transfer of heat to the soldering iron tip guaran-
tee the high performance capability of the soldering iron. Using
an integrated equipotential bonding wire, it is possible to equi-
potentially bond the soldering iron tip as required. The anti-sta-
tic design of the handle and cable comply with the requirements
for electrostatic sensitive device safety.

3. Commissioning

Place the soldering iron in the safety stand. Insert the soldering
iron plug in the socket on the power supply unit and lock. Switch
on the power supply unit and set to the desired temperature.
As standard, the soldering iron is equipped with an HT 2 (5 mm)
tip. Various shapes and widths of bit are available. Choose the
one best suited to your requirements from the range.
The temperature is set in a range between 50 °C (150 °C) and
450 °C. A blinking LED in the display signals that the preset tem-
perature has been reached – this serves as a optical regulator.
Constant illumination means that the system is overheating.
Maintenance
The sensor and heater element are built into a corrosion resi-
stant stainless steel body. To ensure optimal heat transfer, this
5
body has a conically shaped tip that fits snugly in the soldering
iron tip. Please ensure that this joint is not degraded by dirt,
foreign bodies, or damage since this would have an effect on the
precision of the temperature regulation.
4. Notes on Use
Tip Changing
The method of fixing the tip to the LR 82 enables tips to be chan-
ged rapidly and ensures their accurate positioning without the
need to undo the tip sleeve.
Removing the Tip
Position 10 AF open ended spanner and ensure correctly sea
ted. Press the tip axially to the stop
to the stop and remove to the front.
2
Fitting the New Tip
Put the open ended spanner on the cold tip, then place on the
heater element. Pay attention to correct positioning.
1.Press the tip into the sprung heater element to the stop
2.Turn the tip anticlockwise to the stop and remove the open
ended spanner.
HT soldering iron tips are long life tips, i.e. the life of the tips is
considerably increased by galvanically coating the copper core
with corrosion resistant material. Any form of mechanical re-
finishing of the tip, including abrasive cleaning, will destroy this
protective layer and reduce the life of the tip.
When heating up the selectively tinned tips for the first time, wet
the tip with solder. This will remove oxide layers that have built
up on the tip in storage. Always ensure that the soldering iron is
placed in the safety stand with a well tinned tip before long
breaks between use. Do not use corrosive cleaners or fluxes.
The soldering station used has been set up for a medium size tip.
Variations in temperature can result from changing the tip or the
usage of other tip shapes.
