Description

Control Unit

The WAD 101 is a hot air station that features a wide variety of functions.

Control unit WAD 101IG

The WAD 101IG is an inert gas soldering station designed for the operation of inert gas soldering irons WP 80IG and WP 120IG.

As a result of the use of a microprocessor, the unit is straightforward and easy to use. The control electronics ensure optimal adaptation of the control characteristics to different soldering tools. The soldering tools themselves are detected automatically and assigned the appropriate control parameters. Excellent dynamic behaviour is made possible by the particularly powerful 24 W heater elements. The soldering tool is thus of universal application. The required temperature can be set via 2 buttons (UP/DOWN). Temperatures from 50°C – 550°C (122°F – 999°F) are realisable with hot air soldering tools. When a soldering iron is connected, the adjustment range is automatically limited to max. 450°C (842°F). Required and actual values are displayed digitally. A flashing red LED indicates when the selected temperature is reached, this LED serves as an optical regulator monitor. The continuous illumination of the LED indicates that the system is warming up.

In the case of the control unit WAD 101, air flow is controlled by a finger switch integrated in the handle. The air flow is controlled via a finger operated switch integrated in the handle. The flow rate can be adjusted continuously over the range from approx. 0-10 l/min via a control valve.

The hot air output is free of static charge.

In the case of control unit WAD 101IG, gas flow is controlled by tool stand WDH 10T. The flow rate can be adjusted within the 0-5 l/min range.

Various methods of equipotentially bonding the soldering iron bit, a zero voltage switch, and the anti-static design of the control unit and soldering tools supple ment the high standard of the unit. The possibility of connecting an external input unit extends the functional diversity. Additional functions including timing and interlocking can be realised using the WCB 1 and WCB 2

Input Units, available as optional extras. The extended features of the WCB 2 Input Unit include an integrated temperature measurement unit.

Work can be continued immediately after switching soldering tips, since the temperature is reached again quickly.

See “Accessories” for additional tools.

Commissioning

Place the soldering tool in the holder. Insert compressed air hose with 6 mm outer diameter in the quick action coupling (12). Provide supply of compressed air with 400 kPa (58 psi) dry, oil-free compressed air or nitrogen (N2).

Warning:
When using nitrogen, attention must be paid to satisfactory room ventilation.

Plug the electrical lead from the soldering tool in the 7 pole socket (7) on the front panel and lock. Connect the compressed air hose to the compressed air connection nipple (8). Check that the mains voltage matches that on the rating plate and that the mains switch (1) is in the off position. If the mains voltage is correct, plug the control unit into the mains.

Warning:
Do not direct hot air soldering tools at people or inflammable objects.

Switch on the unit at the mains switch (1). When the unit is switched on, a self-test is performed during which all the indicators (2) are illuminated. The temperature set (required value) and the temperature scale (°C/°F) are then briefly displayed. The electronics then switch automatically to the display of the actual value. The red dot (5) on the display (2) illuminates. This dot serves as an optical regulation monitor. Continuous illumination means that the system is heating up. Flashing indicates that the operating temperature has been reached.

Setting the temperature
The digital display (2) shows the actual value temperature. By pressing the UP or DOWN key (3, 4) the digital display (2) switches to the setpoint. The setpoint can be changed by tapping or by firmly pressing the UP or DOWN button (3, 4) in the desired direction. Pressing the button will change the setpoint quickly. The digital display (2) returns automatically to the actual value approximately 2 seconds after releasing the button.

Adjusting the Air Flow Rate
The air flow rate required can be adjusted at the flow control valve (9). Turning the control valve (9) to the left increases the flow rate. Air is fed to the hot air soldering tool as long as the finger operated switch is held down.

Standard setback for control unit WAD 101
: Setting back the set temperature to 150°C. The setback time, which follows the switching of the soldering station to standby mode, is 20 minutes. After three setback times (60 minutes) the ”AUTO-OFF” function is activated. The soldering tool is switched off (blinking line on the display).

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 temperature is reduced to 180°C and inert gas feed is shut off after 2 min. The “AUTO-OFF” function is deactivated.

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.

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 tinnable 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 changed or if other bit shapes are used.
