Check and Measure the Soldering Iron

When there is something wrong with soldering iron, you can check and test it. If it is broken, replace the broken element.

1. Checking soldering iron: disconnect the plug and measure the resistance value between the connecting plug pins as follows:

2. If the values of 'a' and 'b' are outside the value in the following table, replace the heating element (sensor) and /or cord assembly. Refer to the following steps.


  • The soldering iron must be equipped with tip, when check b and c items.
  • The order of the pins in the above picture is as the mark on the handle socket.

Disassembling the soldering iron

1) Turn the nut (1) counterclockwise and remove the tip enclosure (2), and the tip (3).

2) Turn the nipple (4) counterclockwise and remove it from the iron.

3) Pull both the heating element (10) and the cord assembly (11) out of the handle (7). (Toward the tip of the iron).

4) Do not use metal tools such as pliers to remove tip or tip enclosure from the handle.

Checking the Heating Element

1. Measure the heating element when it comes back to room temperature:

1) Resistance value of heating element under 4Ω.

2) Resistance value of sensor (Red and Grounding wire) under 10Ω.

2. If the resistance value isn't normal, replace the heating element.

3. Testing heating element:

1) Measure the resistance value between pins 4 and 1 or 2, pins 5 and 1 or 2, pins 3 and 1 or 2, pins 3 and 4 or 5. If it is not ∞, the heating element and sensor or vibrator switch are touching. This will damage the PCB.

2) Measure the resistance value a, b and c to confirm that the leads are not twisted and that the grounding wire is properly connected.

3) Make sure the spring hook (9) has clasped the heater element (10).

ASE-1203: Setting & Operating the Unit

Usages of the Sponge and the Iron Holder


  • The sponge is compressed. It will swell when moistened with water. Before using the unit, dampen the sponge with the water and squeeze it dry. Failure to do so may result in damage to the Soldering tip.
  • During the work, add water to the holder base if the sponge becomes dry.

1. Dampen the small cleaning sponge with water and then squeeze it dry. Place it in the iron holder base.

2. Add water to iron holder base. The small sponge will absorb water to keep the large sponge above it wet.

3. The large sponge may be used alone (without small sponge & water). Dampen the large cleaning sponge and place it on the iron holder base.



Be sure to turn off the power switch before connecting or disconnecting the soldering iron. Failure to do so may result in damage to the soldering station.

1. Connect the cord assembly to receptacle.

2. Place the soldering iron in the iron holder.

3. Be sure to ground the unit. One end of the unit connects with the grounding hole at the back of the unit, and the other end connects with the earth.

4. Plug the power cord into a power supply. Turn on the power switch.

5. The heater point (the radix points on the 1's right side) flickers when the temperature has stabilized.

Frequently Asked Questions

  • How to care and use of the soldering tip?
  • How to clean the tip?
  • What temperature should use for soldering?
  • Why a "de-tinned" tip fails to work?

  • How to care and use of the soldering tip?

    High soldering temperatures can degrade the tip. Use the lowest possible soldering temperature. The excellent thermal recovery characteristics ensure efficient and effective soldering event at low temperatures. This also protects the sensitive components from thermal damage. Clean the tip regularly with a cleaning sponge, as oxides and carbides from the solder and flux can form impurities on the tip. These impurities can result in defective joints or reduce the tip's heat conductivity. When using the soldering iron continuously, be sure to loosen the tip and remove all oxides least once a week. This helps to prevent reduction of the tip temperature. Never leave the soldering iron sitting at high temperature for long periods of time, as the tip's solder plating will be covered with oxide, which can greatly reduce the tip's heat conductivity. Wipe the tip and coat it with fresh solder after use. This helps to prevent tip oxidation.


    How to clean the tip?

    Caution! Never file the tip to remove oxide.

    1. Set the temperature to 250C.
    2. When the temperature stabilizes, clean the tip with the cleaning sponge and check the condition of the tip.
    3. If there is black oxide on the solder-plated portion of the tip, apply new solder (containing flux) and wipe the tip on the cleaning sponge. Repeat until the oxide is completely removed. Coat with new solder. The solder protects the tip from oxidation and prolongs the life of the tip.
    4. If the tip is deformed or heavily eroded, replace it with a new one.


    What temperature should use for soldering?
    600- 650F (316- 343C) is a good place to start for lead-based solder and 650- 700F (343- 371C) for lead-free solder.

    Note: if clots form, the temperature is too low.

    Why a "de-tinned" tip fails to work?

    A de-tinned tip is one which cannot wet with solder. This exposes the plating to oxidation and degrades the heat transfer efficiency of the tip.

    The de-tinning is caused by:

    1) Failure to keep the tip covered with fresh solder while not in use.

    2) High tip temperatures.

    3) Insufficient melting in soldering operations.

    4) Wiping the tip on dirty or dry sponges and rags (Always use a clean, wet, industrial grade, sulfur-free sponge).

    5) Impurities in the solder, iron plating, or on the surfaces to be soldered.
