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 resi-
stance 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 solde-
ring 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 solde-
ring 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 chan-
ged 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 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 precisi-
on 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.
The soldering equipment has been set up for a medium size
bit or nozzle. Variations may occur if the bit is changed or if
other bit shapes are used.
