5. USB Interface
The WD 2 M control unit is equipped with a Mini USB inter-
face as standard. This can retrofitted on the WD1 control
unit. WELLER standard software (CD is included in scope of
supply) has been provided to use the USB interface). This
software contains a firmware updater and monitor software.
The firmware updater can be used to carry out a software
update, whereby the control unit can be provided with the
most up-to-date operating software.
The monitor software can be used for remote control of the
unit. Temperature curves can also be presented graphically,
printed out and saved.
7. Potential balance
Due to the different circuits in the 3.5 mm switch jack sok-
ket (8), 4 variations are possible:
Hard-earthed: without plug (delivery status)
Potential balance with plug, balance line at
(impedance 0 Ohm): middle contact
Potential-free: with plug
Soft-earthed: with plug and soldered resistor.
Earthing via selected resistance
value.
8. Operating guidelines
During the first heating-up period, coat the selected tinnable
soldering tip with solder.This removes oxide layers and con-
tamination on the soldering tip caused by storage. Never use
an aggressive flux.
The transition between heating element/sensor and the sol-
dering tip must not be impaired by dirt, foreign bodies or
damage because this would affect the accuracy of the tem-
perature control.
Handling the soldering tips
Select as low a working temperature as possible
Select the largest possible soldering tip form for the
application
Rule of thumb: approx. as big as the soldering pad
Guarantee a large-surface heat carriage between solde-
ring tip and solder joint by properly tin-plating the solde-
ring tip.
Before long work breaks, switch the soldering system
off, or use the Weller function for temperature decrease
when not in use.
Coat the tip before placing the soldering iron in the rest.
Apply solder directly to the solder joint and not on the
soldering tip.
Use the corresponding tool to change the soldering tips.
Never apply mechanical force to the soldering tip.
