Names of Parts

Setting up the HAKKO 950

1. Affix the caution sticker to the station
   The HAKKO 950 cannot be used at temperatures above 400 C (752 F). Higher temperatures may damage the station. Be sure to affix the caution sticker to the station. When using the HAKKO 950 SMD Hot Tweezer, do not operate this station temperatures over 400 C (752 F).

2. Install the Heat Resistance Pad
   Insert the cord plug through the hole in the Heat Pad. The Heat Pad is used when the soldering tip is replaced.

Iron holder
(Optional, part no. C1313)
An optional iron holder (part no. C1313) is available for use with the HAKKO 950.

1. Dampen the small cleaning sponge with water and squeeze it dry. Place it in one of the 4 openings in the iron holder base.

2. Add water to approximately the level shown in the illustration. The small sponge will absorb water to keep the larger sponge above it wet at all times.
   Note: The large sponge may be used separately (without the small sponge and water)

3. Dampen the large cleaning sponge and place it on the iron holder base.

 Connections

1. Connect the Plug to the receptacle.
2. Place the HAKKO 950 in the iron holder.
3. Plug the power cord into the power supply. Be sure to ground the unit.

Calibration

Before operating the HAKKO 950, be sure to calibrate the station using a tip thermometer (HAKKO 191 Thermometer or 192 Soldering Tester. When calibrating the tip for removing SOP´s, place the edge of the tip on the measuring point of the HAKKO 191 or 192, See sketch.).
Please refer to the instruction manual for your station.

CAUTION
The sponge is compressed. It will swell when moistened with water. Before using the unit, dampen the sponge with water and squeeze it dry.
Always use a damp sponge to clean the tip. Never wipe the tip clean on a dry sponge as this can damage the tip.

Replacing the Tip/Tip selection

Replacing the Tip

CAUTION
Be sure to turn off the power switch before replacing the tip.

1. Loosen the nipple by turning it counterclockwise. It is not necessary to pull it out completely.
2. When the tip is heated, grasp the pipe part using the heat resistance pad of the tip and pull.
3. Insert the new tip as far as it will go, and align it so that it is parallel to the other tip.
4. Tighten nipple to fix the tip in place.

Tip Selection (Refer to P13)
The tip temperature will vary according to the shape of the tip. The preferred method of adjustment uses a tip thermometer. (See your station’s instruction manual.) Less accurate methods include adjusting the temperature control knob and calibrating with a room thermometer.

CAUTION
Use only genuine HAKKO 950 replacement tips.

Use the tip alignment tool to easily align the two tips in parallel.

CAUTION

The tip is very hot. If handled improperly,
it can cause serious burns.
Do not hold onto the heat resistance pad for a long period.

1. Dial type station
   Example: When using an SOP 25L tip at a temperature of 400 C (750 F), the differ-ence between this tip and CHIP 2L is -5 C (-9 F).
   Set the temperature control knob to 405 C (759 F).

2. Digital type station
   Digital-type stations can be calibrated with a room thermometer. Refer to the compensation value chart below.
   Specific instructions can be found in your station’s instruction manual.

Operating Instructions

1. Set the Temperature
   CAUTION
   Never set the temperature to any value over 400˚C (752˚F). Doing so may damage the station.
   Set the temperature according to the type of work to be done.

2. Apply solder or flux.
   If there is insufficient solder on the PWB, or the soldered area is too small, apply solder or flux to the PWB. Solder may also be applied to the tip.

3. Melt the solder
   Place the tip on the soldered part and melt the solder. Confirm that the solder is fully melted. See sketch `A´.

4. Remove the component
   After confirming that the solder is fully melted, lightly squeeze the tweezer to grasp the component and lift to remove the component. See sketch `B´.

CAUTION
(For users of the HAKKO 937 Soldering Station)
The HAKKO 950 contains a sensor-—attached to the heating element in handle B—to detect the tip temperature. The HAKKO 937 Soldering Sta-tion’s heater error function will not operate if the heating element in handle A is broken.

CAUTION
Very high tip temperatures may damage the printed circuit board, possibly causing the printed pattern to become detached. HAKKO recommends setting the tip temperature to 300˚C (572˚F) for all normal work, and raising it only when a specific job requires a higher temperature. Using the lowest possible effective temperature not only helps protect parts that are sensitive to heat, it also helps protect the tip from deterioration caused by heat.

Troubleshooting Guide

WARNING

Disconnect the power plug before servicing. Failure to do so may result in electric shock.
More information can be found in your station’s instruction manual.

Checking for breakage of the heating element, cord assembly, and tip-to-

ground resistance

Disconnect the plug and measure the resistance between the connecting plug pins as follows.
If the values of ‘a’ and ‘b’ are outside the ranges shown in the chart, replace the heating element (sensor) and/or cord assembly.

Broken heating element

CAUTION

Be sure to measure the resistance of the heating element in both handles A and B. If one of the heating elements is found to be broken, replace both heating elements.
Disassembling the HAKKO 950 (Refer to P11,12)

1. Loosen the nipple by turning it counterclockwise.

2. Pull out the tip.

3. Remove the screw.

4. Remove the strut pin, and detach handles A and B.
   CAUTION
   Do not lose the tension spring.

5. Remove the self-tapping screw and the handle cover.

6. Pull out the PWB and the heating element.

Measure when the heating element is at room temperature.

1. The resistance value of the heating element (RED) 2.5 – 4.5
2. The resistance value of the sensor (BLUE) is 43-58 @If the resistance value is not normal, replace the heating element.
   (Refer to the instructions included with the replacement part.)

Broken Cord
There are two methods of testing the cord.

CAUTION
The LED heater lamp will flicker even with a normal cord if the temperature reaches 400˚C (752˚F).

Checking the tip-to-ground resistance

If the value of ‘c’ (between pin 3 & tip) is over the above value 2 as measured with a tester, remove the oxidization film by lightly rubbing with sand-paper or steel wool the points shown below.

1. Turn the unit ON and set the temperature to 400˚C(752˚F). Then wiggle and kink the iron cord at various locations along its length, including the strain relief area.
   If the LED heater lamp flickers, then the cord needs to be replaced.

2. Check the resistance between the pin of the plug and the wire on the terminal in the handle B.

3. Pin 1: Red

4. Pin 2: Blue

5. Pin 3: Green

6. Pin 4: White

7. Pin 5: Black
   The value should be 0 . If it is greater than 0 or is , the cord should be replaced.

Maintenance

Inspect and Clean the Tip

CAUTION
Never file the Tip to remove oxide.

1. Set the temperature to 250 C (482 F).
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.
4. If the tip is deformed or heavily eroded, replace it with a new one.

Tip Care and Use

• Tip Temperature High operating temperatures can degrade the tip. Use the lowest possible operating temperature.
• Cleaning 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 Not in Use Never leave the HAKKO 950 sitting at high temperature for long periods of time, as the tip’s solder plating will become covered with oxide, which can greatly reduce the tip’s heat conductivity.
• After UseWipe the tip clean and coat the tip with fresh solder. This helps prevent tip oxidation.
