Frequently Asked Questions - SPI 41 Weller

How to adjust the temperature on the Weller SPI 41?

Use the adjustment knob on the front panel to set the temperature between 200 °C and 450 °C. The actual temperature is displayed on the LCD screen.

Which tip to use for soldering SMD components?

For SMD, use a fine tip (type ET-B) for optimal precision. Make sure it is well tinned.

Why does my soldering iron tip turn black?

A blackened tip indicates oxidation due to too high temperature or lack of tinning. Clean it with a damp sponge and re-tin it with solder.

How to activate automatic standby mode?

Standby mode activates automatically after 20 minutes of inactivity. The temperature drops to 200 °C to save energy and extend tip life.

Can I use the Weller SPI 41 to solder thick wires?

Yes, but choose a wider tip (type ET-D) and increase the temperature to 350-400 °C for good heat transfer.

How to replace the soldering iron tip?

Unplug the station, wait for the iron to cool down, then unscrew the fixing nut and remove the old tip. Insert the new tip and tighten the nut.

What to do if the displayed temperature is unstable?

Check that the tip is properly inserted and that the heating cable is not damaged. If the problem persists, contact customer service.

What is the temperature calibration procedure?

Calibration is done using an external thermometer. Follow the instructions in the manual to access calibration mode and adjust the displayed temperature.

Does the soldering iron heat up quickly?

Yes, the Weller SPI 41 reaches working temperature in less than 30 seconds thanks to its ceramic heating element.

How to clean the station stand?

Use a damp cloth to clean the housing. For the iron stand, remove the grid and clean it with a wire brush to remove solder residues.

Safety information

The soldering tool must be operated only in perfect technical working order. Safety devices must not be deactivated.

Faults and defects must be repaired immediately. Before using the unit / tool, safety devices must be carefully checked to make sure that they are functioning properly and in the manner intended. Check that moving parts are functioning properly and are not sticking, and whether parts are damaged. All parts must be correctly fitted and must satisfy all the requirements necessary to guarantee troublefree operation of the unit.

For safety reasons, children and youths under the age of 16, as well as persons who are not familiar with these operating instructions, may not use the device. Children shall not play with the appliance.

This device is not intended for use by persons (including children) with limited physical, sensory or mental aptitude, or by persons who lack knowledge or experience in handling the device.

Keep other persons well away from your workplace.

The work area is out of bounds for children and unauthorised persons. Never allow other persons to touch the soldering tool or cable.

WARNING

Danger of injury

The device or parts of the device may fall off during transportation.

WARNING

Danger of injury

Danger of crushing injuries! / Cutting hazard

Risk of injury after opening the hood, as no protection against moving parts is provided.

• The key-operated switch may only be used by specialist, trained personnel, who are fully aware of the risks involved in operating the machine without any protective function, thanks to their specialist qualification and experience.
  • The key must be kept in a safe place.
• Do not leave the key in the switch during normal operation of the machine!
  Risk of injury on interchangeable magazines
• Never put your hand inside the device when the magazine is open

Danger: compressed air.

- Take care when fitting the compressed air connection. Depressurise the hose. When soldering, hold the coupling firmly as the coupling socket can spring out of your hand.

WARNING

Electrical shock

Protect yourself against electric shocks.

• Do not use the soldering tool in a damp or wet environment.
• Before doing any work on the machine, pull the plug out of the socket. Leave the unit to cool down.

Connecting the control unit incorrectly poses a risk of injury due to electric shock and can damage the device.

• Carefully read the attached safety information, the safety information accompanying these operating instructions as well as the operating instructions for your control unit before putting the control unit into operation and observe the safety precautions specified therein.
• Only connect WELLER tools.
  If the device is faulty, active electrical conductors may be bare or the PE conductor may not be functional.
  • Repairs must always be referred to a Weller-trained specialist.
• If the electrical tool's power supply cord is damaged, it must be replaced with a specially prefabricated power supply cord available through the customer service organisation.

WARNING

Fire hazard

• Keep all combustible objects, liquids or gases well away from the hot soldering tool.
• Once switched on, never leave the tool unattended.

WARNING

Risk of burns

The soldering tip becomes very hot during soldering work. There is a risk of burns from touching the tips. Tools may still be hot long after they have been switched off.

• Do not touch the hot tools and workpieces.
• Only replace solder tips when cold
• Do not touch the housing until it has cooled down.

After the soldering process, the soldering tool and the workpiece holder are still hot.

• Soldering profiles must be configured so that the printed circuit boards are cold on removal.
• Wear gloves when removing the printed circuit boards. Care must be taken to ensure that hot printed circuit boards are beyond the reach of third parties after removal.

WARNING

Danger of poisoning

• The soldering process can produce hazardous solder vapours. Hazardous vapours and other aerosols may be released when printed circuit boards are heated and/or overheated. Use a solder fume extraction unit.
• When working with adhesives, special attention must be paid to the warning information provided by the adhesive manufacturer.
• Avoid skin contact with the adhesive or the solder paste. Skin contact with these substances can have adverse health effects.

The power cable must only be plugged into the power socket or adapter approved for this purpose. Check to see if the mains voltage matches the ratings on the nameplate. Make sure the machine is switched off before plugging in.

Do not use the cable for purposes other than those for which it is intended. Never carry the unit by the cable. Do not use the cable to pull the plug out of the socket. Protect the cable against heat, oil and sharp edges..

Be alert. Pay attention to what you are doing. Be smart when using the unit. Do not use the soldering tool if you are having difficulty concentrating.

Avoid abnormal posture. Arrange your work station in an ergonomically correct way. Avoid bad posture when using the unit, as this can lead to postural problems.

Use the correct tool. Use only accessories or auxiliary devices which are included in the list of accessories or approved for use by the manufacturer. Use WELLER accessories or auxiliary devices on original WELLER equipment only. The use of other tools and other accessories can cause injury.

Store your soldering tool in a safe place. When not in use, units and tools should be stored in a dry, high or locked area out of the reach of children. Make sure that unused soldering tools are free of voltage and de-pressurised.

Fix the axles in place during transport using cable ties.

Specified Conditions Of Use

The soldering installation may only be used to piston solder assemblies.

This device may only be used at room temperature and indoors. Protect against moisture and direct sunlight.
