LR 82
Operating Instructions
Thank you for placing your trust in our company by purchasing the Weller soldering iron LR 82. Production was based on stringent quality requirements which guarantee the perfect operation of the device.
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.
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 guarantee the high performance capability of the soldering iron. Using an integrated equipotential bonding wire, it is possible to equipotentially bond the soldering iron tip as required. The anti-static design of the handle and cable comply with the requirements for electrostatic sensitive device safety.
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 temperature 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 resistant 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.
Notes on Use
Tip Changing
The method of fixing the tip to the LR 82 enables tips to be changed 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 . Turn the tip clockwise 1 to the stop and remove to the front. (Page 26) 2 3 Fitting the New Tip Put the open ended spanner on the cold tip, then place on the heater element. Pay attention to correct positioning.
- Press the tip into the sprung heater element to the stop
- 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 refinishing 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.
