Equipotential Bonding; Instruction For Use - Weller WAD 101 Operating Instructions Manual

English

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 exter-
nal 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 acti-
vated. 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" functi-
on. 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 AF 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 ele-
ment.
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 tin-
nable 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 soldering and when placing in the holder.
Do not use aggressive fluxes.
Important: Always ensure that the soldering iron bit is
correctly seated.
The soldering equipment has been set up for a medium
size bit or nozzle. Variations may occur if the bit is chan-
ged or if other bit shapes are used.
