17. 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. Do not carry the soldering
equipment connected up to the mains with the finger on the master switch.
18. 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.
19. 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 fitted cor-
rectly and have to meet all conditions in order to safeguard perfect operation of the solde-
ring 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.
20. Warning.
Please only use the accessories or optional devices which are mentioned in the list of
accessories in the operating instructions. Use Weller accessories or optional devices on ori-
ginal Weller equipment only. The use of other tools and other accessories may cause inju-
ries.
21. 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.
22. Do not work on live parts.
The handle is conductive on antistatic soldering equipment.
23. Do not connect any combustible gases.
No combustible gases may be connected to hot-air, respectively hot-gas devices. Do not
point the hot gas jet at persons, respectively do not look into the hot-gas jet. Provide for
sufficient ventilation in case of internal gases.
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 WELLER WMD 3 control unit is suitable for simultaneous operation of 3 soldering tools.
For this purpose, 3 channels are available. No special setting operations are required,
because the microprocessor automatically detects the connected tool and activates the
corresponding control parameters.
Temperature is controlled digitally, and the desired process parameters can be entered by
means of four keys. A further key switch enables the input functions to be locked. Entered
parameters are retained even after the unit is switched off.
Various time functions, such as temperature reduction to 150˚C on the soldering/de-solde-
ring bit, or time limitation for the de-ionised hot air flow, can be set straightforwardly.
Units are equipped with an integral high-performance pump. This is started by a micros-
witch which is incorporated in the handle, or an optional footswitch. The supply unit is
equipped with a pointer pressure gauge for the purpose of vacuum display. This also indi-
cates the degree of dirtying of the filter cartridge.
The metal casing is treated with anti-static paint, and fulfils the EGB safety requirements.
Equipotential bonding, if desired, can be achieved by means of a pawl socket on the unit's
backplane. The station is grounded as a part of standard equipment.
