The display shows the current temperature of the soldering tip in
large digits and below that the set target value in smaller digits.
In addition to the target value, a heating symbol appears when
the iron is heating up. Even when the standby function is active
or when the lock-out function is used, the corresponding symbols
are still displayed.
Due to its weight the soldering iron holder stands well on the table.
It has a number of holes to accommodate spare tips. To wipe the
tip clean there is, of course, the customary yellow sponge. There
is no room for brass wool or the like. If you prefer using such a
bundle of metal wool to wipe the tip you’ll have to buy an extra
container with metal wool.
The soldering iron itself is quite slim and the flexible cable is nice
and long. It is also so flexible that you hardly notice it when solder-
ing. The soldering tips can be changed simply by unscrewing the
metal sleeve of the front part using a plastic nut (Figure 3). It is
because the tip is indirectly heated, as already mentioned, that
replacement tips are very inexpensive — even the original
ones from Weller. They are available almost everywhere
and I have already bought some with other tip
shapes (Figure 4).
Lighting up!
After switching on it took around 35 seconds until the soldering
tip had reached a temperature of 350°C. The 380°C needed for
lead-free solder needed around 5 seconds more. Soldering with
the WE P70 soldering iron works smoothly. There are no problems
when soldering average components and standard copper pads.
With large soldering surfaces you will notice that the temperature
drops a bit and the tip needs a few seconds to reach the set point
again (an active soldering iron reacts much faster in such cases),
but this only takes a short time thanks to its 70 W heating power.
In such cases it is advisable to use a short soldering tip with a large,
bevelled tip so that the heat can be transferred more optimally.
The tip supplied is rather too narrow for this and is better suited
Purchased
So the decision fell for the WE 1010 consisting of a base station with
LCD display and a soldering iron with a power of 70 W. Although
this is a soldering iron with passive temperature control (heating
and sensor are not in the tip itself but behind it) I don’t think it is
an issue (more on this later). The box contains a base station with
matching power cord, a WEP 70 soldering iron, a fairly simple stand
consisting of a moulded base with a holder that is inserted into it,
and a sponge. It all looks rather ordinary but everything is neatly
finished. On the station there is an on/off button, an LCD and some
control buttons (Figure 2).
Unfortunately, the display is not backlit. However, it is very clear
and easy to read, even with little ambient light. Alas the power
switch has no built-in lighting either. Thus you can only see that
the station is on because something is visible on the display and
the power switch, in the on position, shows a red line.
The base station is quite heavy (almost 2 kg) and feels solid. The
1.5 m long cord (with silicone sheath) on the soldering iron is very
supple and it lies well in the hand with its covering of a kind of
pressed foam. The cable of the soldering iron has a 5-pole plug at
the end which is inserted into the socket on the base station, then
locked by turning. The metal part of the soldering iron is connected
to the earthed socket of the mains cable. There is no separate earth
connection on the station.
Operation and use
The operation of the soldering station is kept very simple. With
the up and down buttons the temperature can be set higher or
lower. On delivery it is preset to 350°C. There is also a menu key
with which you can access the following settings: standby time,
the time after which the soldering iron is switched back to a lower
temperature (max. 99 minutes); offset, for temperature correc-
tion and only useful if you can measure the temperature of the tip
(max. ±40°C); switching between °C and °F; and finally the abilty
to set a lock code.
