Weller WAD 101, Manual

Page: 7 / 12

Setting: When switching on, hold the ”UP” key (3) until ON or
OFF appears in the display.
The setting is saved when the "UP" button is released.
Repeat this step to change.
Standard setback for control unit WAD 101IG
After placing the soldering iron on its stand, the nominal tem-
perature is reduced to 180°C and inert gas feed is shut off
after 2 min. The "AUTO-OFF" function is deactivated.
4. Equipotential bonding
The various circuit elements of the 3.5 mm jack bush make
4 variations possible:
Hard-grounded:
No plug (delivery form)
Equipotential bonding:
With plug, equalizer at center
contact (impedance 0 Ohms)
Potential free:
With plug
Soft-grounded:
With plug and soldered
resistance. Grounding via set
resistance value.
5. Instructions for use
External input unit WCB 1 and WCB 2 (optional)
The following functions are possible when using an external
input unit.

Offset:
The real temperature of the soldering iron can be changed by
± 40°C by input of a temperature offset.

Setback:
Reduction of the required temperature set to 150°C / 300°F
(standby). The set-back time, the time after which the
soldering station switches into standby mode, can be
adjusted from 0-99 minutes. The set-back condition is
indicated by a flashing actual value display. After a period
equal to three times the set-back time, „AUTO-OFF“ is
activated. The soldering iron is switched off (flashing dash on
the display). The set-back or auto-off condition is ended by
pressing a button or finger switch pressure. During this
process the required value set is briefly displayed.

Lock:
Locking the setpoint temperature. Settings cannot be
changed after the soldering station has been locked.

°C/°F:
Switching the temperature display from °C to °F, and vice
versa.

Window:
Limitation of the temperature range to max. ± 99°C based on
a locked temperature resulting from the "LOCK” function.
The locked temperature represents the median point of the
adjustable temperature range.

Cal:
Re-adjustment of the soldering station (WCB 2 only).

PC interface:
RS232 (WCB 2 only).

Temp. gauge:
Integrated temperature gauge for thermal element Type K
(WCB 2 only).
Hot Air Soldering Tool
The hot air nozzles are screwed into the heater element. To
change the nozzle use the 8 SW socket spanner and lock the
heater element with an open ended spanner.
Important:
The maximum thread depth is 5 mm (0.2").
A longer thread will irreparably damage the heater
element.
Nitrogen N2 reduces oxidation and flux remains active for
longer. We recommend the nitrogen N2 that is available in
steel bottles. The bottle must be equipped with a 0-10 bar
pressure reducer.
Soldering Iron
The transition between the heater element/sensor and the
soldering iron bit must not be degraded by dirt, foreign bodies
or damage because these will have an effect on the
precision of temperature regulation.
When heating up for the first time, wet the selectively tinna-
ble soldering iron bit with solder. This removes oxide layers
and soiling that have formed during storage. Always ensure
that the soldering iron bit is well tinned during breaks in sol-
dering and when placing in the holder. Do not use aggressi-
ve fluxes.
Important:
Always ensure that the soldering iron bit is correctly
seated.
