Frequently Asked Questions - MG100S Weller

How to set the stand-by temperature?

Access Menu 1 by pressing the menu key. Select the desired channel. Navigate to 'Stand-by Temp.' and set the temperature between 100-300 °C (or OFF to disable). Confirm with the menu key.

What to do if the screen shows 'OFF' and the tool remains cold?

This means the station is in stand-by or Auto-OFF mode. Press UP or DOWN keys to reactivate the tool. If the display flashes 'COOLING', wait until the temperature drops below 50 °C before reuse.

How to lock the station to prevent accidental changes?

In Menu 1, select 'LOCK'. Enter a 3-digit code (001-999) and confirm. A padlock appears on the screen. To unlock, press the menu key, enter the same code and confirm.

What does the error message '- - -' mean?

The tool was not detected or is faulty/incompatible. Check the tool connection to the station and its condition. Replace the tool if necessary.

How to adjust the actual temperature if it does not match the setpoint?

Use the 'Offset' function in Menu 1. You can enter an offset of ±40 °C (±72 °F) to compensate deviations. Confirm with the menu key.

Can I use the station with a Zero Smog fume extractor?

Yes. In Menu 2, set the potential-free switching output to 'ES FE' (factory setting). Connect the extractor to the dedicated output. Refer to the wiring diagram in the manual.

How to reset the station to factory settings?

Turn off the station. Press and hold the 'Exit', 'UP', and 'DOWN' keys simultaneously, then turn it on. Continue pressing for 3 seconds until the screen shows the reset.

What are the maintenance precautions for the tip?

Tin the tip after each use and before storage. Do not use aggressive fluxes. Fasten the tip correctly. To change, use the provided tool without forcing. Turn off the station during long breaks.

The station does not heat up although the display works, what to do?

Check that the station is not in stand-by mode (press UP/DOWN). If the tool remains cold, the heater may be defective. Test with another compatible tool or contact technical support.

How to change the temperature unit between °C and °F?

In Menu 1, navigate to the '°C °F' option. Select '°C' or '°F' with the UP/DOWN keys and confirm with the menu key.

USER MANUAL MG100S Weller

First choose the channel you wish to setup.

Pressing the Menu button takes you to menu 1

Pressing the Menu button will take you into the menu of the previous selected channel.

Always make sure that the channel you have selected is the wished channel. The previously selected channel is shown on the display.

If no channel is displayed, the changes refer to the entire device.

Standby Temp.

The standby temperature is a preset value to which a soldering tool is adjusted when not in use.

Option Description
OFF Standby	deactivated (factory setting 180°C (360°F)
100-300 °C	Standby Temp., Individually adjustable
200-600 °F

Standby time (temperature deactivation)

On soldering tools with a usage sensor in the handle, the soldering tool is adjusted to the standby temperature after the preset standby time if not in use. The sensor integrated in the tool detects changes in status and deactivates standby mode as soon as the tool is moved.

On soldering tools without a usage sensor, the soldering tool is adjusted to the standby temperature after the preset standby time if no soldering process is being performed.

Pressing the UP and DOWN buttons exits standby mode.

(Not available for: WMRP, WMRT, which are controlled via a magnetic contact)

Option Description
OFF Standby	deactivated (factory setting 2 min)
1-99 min Standby Time, Individually adjustable

OFF time

If the soldering tool is not in use, the heating for the soldering tool is deactivated after the OFF time elapses. Temperature deactivation is performed independently of the set standby function. The actual temperature is indicated by flashing LED and serves as a residual heat display. The display reads "OFF".

As long as the soldering tool cools, the residual heat is displayed in the 1-channel display. Cooling also flashes in the display. COOLING

For the 2-channel display, °C / °F flashes in the display of the corresponding channel.

As soon as the temperature falls below 50 °C (122 °F), OFF appears in the display and the backlighting is deactivated.

Pressing the UP and DOWN buttons at the same time exits OFF mode.

Option 12	Description
OFF OFF time	Deactivated (factory setting 10 min)
1-999 min	OFF time, Individually adjustable

Window function

Option 1 (factory setting):

Set the potential-free switching output to ES FE.

Limiting the adjustment range to ±1-99 ^ ( ±1-180 ^ ) based on a temperature locked using the „LOCK“ function.

The locked temperature therefore represents the middle of the adjustable temperature window.

Option 2:

Set the potential-free switching output to ES rob; ES FE / rob; ES rob / rob.

Starting from a set, locked temperature, it is possible to set a temperature window of ± 1 - 99^ ( ± 1 - 180^ ) using the WINDOW function. If the actual temperature is within this window, the potential-free contact (optocoupler output) becomes conductive.

Option 12	Description
OFF Window	function Deactivated (factory setting OFF)
1-99 °C	Window function, Individually adjustable
1-180 °F

LOCK

Lock for the station. After the station is locked, it is no longer possible to change any device settings.

Exception 1: Fixed temperature buttons activated.

Exception 2: Window function Option 1.

All other settings are disabled until the station is unlocked again.

Locking the station

Set the three-digit locking code of your choice (between 001 and 999) and confirm by pressing the Menu button.

The lock is active (the display shows a lock symbol)

Unlocking the station

Press the Menu button. ON appears in the display

Set the three-digit locking code.

Press the Menu button to confirm the code.

Tool recognition and overload limiting

The WT 2M has automatic tool recognition which assigns the relevant control parameters to the connected tool. To prevent overloading a station, only compatible tools are supported:

- Power reduction to 150 W

✗ Tool combination not possible

Equipotential bonding

Four variants are possible by connecting the 3.5 mm jack socket differently:

a Hard-grounded supplied without plug.
b Equipotential bonding with plug, equaliser at centre contact.
c Floating with plug
d Soft-grounded with plug and soldered resistor. Grounded through selected resistor.

Soldering and desoldering

Carry out soldering work as directed in the operating instructions of your connected soldering tool.

Handling the soldering tips

• Coat the selective and tinnable soldering tip with solder when heating it up for the first time. This removes oxide coatings which have formed during storage and impurities from the soldering tip.
• Make sure that the soldering tip is well coated with solder during breaks between soldering work and prior to storage of the device.
• Do not use aggressive fluxing agents.
  • Always make sure that the soldering tips are fitted properly.
• Select as low a working temperature as possible.
• Select the largest possible soldering tip shape for the application. Rule of thumb: the soldering tip should be roughly as large as the soldering pad.
• Coat the soldering tip well with solder to ensure that there is efficient heat transfer between the soldering tip and the

soldering area.

• Prior to extended breaks between soldering work, switch off the soldering system or use the Weller function to reduce the temperature when the soldering equipment is not in use.
• Coat the tip with solder prior to storage if you do not intend to use the soldering iron for an extended period of time.
• Apply solder directly to the soldering area, not to the soldering tip.
• Change the soldering tips using the designated tool.
• Do not apply mechanical force to the soldering tip.

Notice

The control units have been adapted to hold a medium-sized soldering tip. Discrepancies may occur if the tip is changed or a different shaped tip is used.
