RS PRO 137-2292 LCD Desoldering Station

RS-PRO-137-2292-LCD-Desoldering-Station

Description

137-2292 is designed for lead free desoldering. The quick heat-up and strong vacuum are suitable for all types of DIP components.
Robust design, single hand operation and strong suction provide easy removal of the residual solder from the single-sided or double sided PCBs.

Control Unit
The desoldering gun is micro-processor controlled. The digital control electronics, high-quality sensor and heat exchange system guarantee precise temperature control at the soldering tip.

Desoldering Iron gun
The 90W Desoldering iron gun along with a wide spectrum of soldering tips can be used anywhere in the electronics field.
The high power and gun design make this iron suitable for fine desoldering work. The heating element is made of ceramic and the sensor on the tip can control temperature quickly and accurately.

Operating Instruction

Place the desoldering gun in the separate holder. Then connect the plug to the receptacle on the station and turn clockwise to tighten the plug nut. Check that the power supply is corresponding to the specification on the type plate and the power switch is in the “OFF” position. Connect the control unit to the power supply and switch on the power. A self-test will be carried out in whichall display elements are switched on briefly. The electronic system then switches on automatically to the set temperature and the value is displayed.

The display and temperature setting

Shows the actual temperature of the desoldering tip.
Shows the setting temperature: Pressing the “UP” or “DOWN” button can switch the digital display to the set point display. The set-point can be changed by ±1℃ by tapping the “UP” or “DOWN” button. Press and hold the button to change the set-point quickly. The digital display will return automatically to the actual value and the iron will reach the setting temperature automatically.
℃/℉ display: Switching the temperature display from ℃ to ℉ by pressing the “ * ”button and then the electronic system will display the actual temperature① and setting temperature② in ℉, and vice versa.
When the actual temperature on the desoldering tip is less than the set-point, “HEAT ON” will display and make the desoldering tip heat up.
When the absolute offset is more than ±10℃ between the actual temperature and the set-point on the desoldering tip or the nozzle, “WAIT” will display. This means that the temperature control system is not in a stable state,wait a moment to let the “WAIT” disappear.
When “—–” & “ERROR” displays, there may be a problem with the system, or the desoldering iron gun is not connected to the control system correctly.

Safety Instruction

The manufacturer assumes no liability for uses other than those described in the operating instructions or for unauthorized alterations.
The operating instructions and cautions should be read carefully and kept in an easily accessible location in the vicinity of the control system. Failure to observe the cautions will result in accidents, injury or risks to health.

Caution

The power cord only can be used in approved power sockets or adapters.
High Temperature
The temperature of the desoldering tip can reach as high as around 400℃(752℉) when the power switch is on. Since mishandling may lead to burns and fire, be sure to comply with the following precautions:
- A. Do not touch metallic parts near the desoldering tip/ nozzle.
- B. Do not use this system near flammable items.
- C. Advise other people in the work area that the unit can reach a very high temperature and should be considered potentially dangerous.
- D. Turn off the power switch while not in use .
- E. Before replacing parts or storing the system, turn off the power and let it cool down to the room temperature.
- F. Warning: this tool must be placed on its stand when not in use.
- G. Fire may result if the appliance is not used with care, therefore:
- a) Be careful when using the appliance in places where there is combustible material.
- b) Do not apply to the same place for a long time.
- c) Do not use in presence of an explosive atmosphere.
- d) Be aware heat may be conducted to combustible materials are out of sight.
- e) Place the appliance on its stand after use and allow it to cool down before storage.
- f) Do not leave the appliance unattended when it is switched on.
Take care of your tools
Do not use the tools for any applications other than desoldering.
Do not tap the iron against the work bench or otherwise subject the iron to severe shocks.
Do not file the desoldering tip to remove the oxide, please wipe the tip on the cleaning sponge.
Use only accessories or attachments which are listed in the operation manual. 3.5 Use of other tools and other accessories can lead to injury.
Please turn off the power before connecting or disconnecting the gun.
Maintenance
Before use, safety devices or damaged parts must be carefully checked for error-free and intended operation.
Inspect moving parts to ensure they don’t bind,and there is no damage to the parts.
Damaged parts must be repaired or replaced by a qualified technician,so long as nothing else is indicated in the operation manual.
Use only accessories or attachments which are listed in the operation manual. Use of other tools and other accessories can lead to a danger of injury.
Keep children at a distance
Warning: this appliance is not intended for use by young children and infirm persons unless they have been adequately supervised by a responsible person to ensure that they can use the appliance safely. Warning: Young children should be supervised to ensure that they do not play with the appliance. When not in use the station should be stored in a dry location which is out of the reach of children. Switch off the desoldering station when not in use.
Work environment
Do not use the desoldering station in a moist or wet environment. The desoldering gun should be placed on the holder after finished using.
Observe the valid safety regulations at your work place.

Warnings

To avoid injury or damage; do not touch metallic parts near the nozzle, do use this system near flammable items.
Ensure power is off and unplugged before performing any maintenance procedure, except during the cleaning process of the nozzle and heating element.
If the pump does not operate, immediately clean the nozzle & heating element, and replace the filter
At high temperatures, the solder waste will become oxidized (lead free solder’s melting point is 220°C, non-lead-free solder’s melting point is 180°C), swelled and stuck tightly on the inner wall. If it is not cleaned after use, the solder waste will block the desoldering gun and will not be able to be removed even with cleaning pin.

Instructions

After each operation is finished, immediately trigger the gun to activate the vacuum pump in free air 3-5 times, this can clean the older waste from inside the pipe.
If used for more than 20 minutes continuously repeat 1. Along with using the cleaning tool.
When you find the desoldering efficiency gets down, please use the cleaning pin to clean the pipe immediately.
If the operation interval is long, we advise to adjust the temperature to about 200°C. When you use it again, you can adjust to the working temperature.
When the glass tube has absorbed about 1/2 solder waste, please clean it immediately. When you find the filter is getting hardened, please replace the filter immediately.

then use the cleaning pin to dredge

Remove solder waste

Pull the lever up “A” and the holder “B”
Take the spring out from the glass tube ,then remove the solder waste
Put the spring back into the glass tube, then fix the glass tube back into position.
Press the rear of the holder back into position (B) , then the lever (A) will move down and lock automatically.
