17. Do not leave any maintenance equipment.

Before switching the equipment on, please check whether all keys and adjustment equip-
ment have been removed.

18. Avoid unintentional operation.

Please make sure that the switch is set off, when connection the plug to the wall outlet,
respectively when connection the equipment to the mains.

19. Be attentive.

Watch out what you are doing. Be sensible in working. Do not use the soldering equipment,
if you cannot concentrate on your work.

20. Check the soldering equipment for potential damage.

Before using the soldering equipment again, please check the safety devices or slightly
damaged parts for perfect function as required. Please check whether the moveable
parts work perfectly and do not jam or whether parts are damaged. All parts have to be fit-
ted correctly and have to meet all conditions in order to safeguard perfect operation of the
soldering equipment. Damaged safety devices and parts have to be repaired or replaced in
an expert manner by an authorised specialist workshop unless nothing to the contrary has
been stipulated in the operating instructions.

21. Warning!

Please only use the accessories or optional devices which are mentioned in the list of
accessories in the operating instructions. Use Weller accessoriesor optional devices on ori-
ginal Weller equipment only. The use of other tools and other accessories may cause inju-
ries.

22. Please have your soldering equipment repaired by an electric expert only.

This soldering equipment corresponds to the pertinent safety regulations.
Repairs my be carried out by an electric fitter only, using original Weller spare parts only,
otherwise the operator may have an accident.

23. Do not work on live parts.

The handle is conductive on antistatic soldering equipment.

24. Use in combination with other Weller devices.

If the soldering equipment is used in combination with other Weller devices, respectively
accessories, the warning notes mentioned in those operating instructions are appliance as
well.

25. Please observe the safety regulations appliance for your workplace.

2. Description

The temperature-controlled WELLER W-series soldering irons are suitable for a broad range
of demanding soldering applications on electrical components with extremely high heat
sensitivity and are therefore ideal for use in industrial production and for maintenance work
on electrical appliances. The industrial soldering irons of the W series have a solidly con-
structed heating element and a wide selection of “Longlife” soldering tips. The various
power classes 60 W, 100 W, and 200 W provide the solution to a multitude of different sol-
dering tasks. Temperature is controlled according to the WELLER Magnastat principle.

If the tip is cold, the permanent magnet is attracted by the ferromagnetic temperature sen-
sor. This actuates the switch. As the sensor approaches the Curie point, it loses its ferro-
magnetic properties and can no longer hold the permanent magnet. The magnet is relea-
sed and the switch returns to its off-position (the power supplied to the heating element is
interrupted). If the tip cools slightly, the temperature sensor attracts the permanent magnet
and power is supplied once again. The temperature sensors (Magnastats) have an extre-
mely narrow distribution of switching temperatures and are not subject to any wear resul-
ting from ageing or material fatigue.

An additional advantage of this design is that the soldering iron is switched off when the
tip is changed. The heating element cannot therefore burn out if the soldering tip is remo-
ved.
