Product Description:

The high-power LF-3300 electronically temperature-controlled soldering station with touchscreen incorporates a special intelligent chip microcomputer control design was developed to meet the present and future lead-free soldering needs of the electronic production industry and is suitable for work on professional SMD electronics. The ergonomic handle with a short distance between the heating element and tip allows very fast heat-up time and quick heat dispersion. The high-quality sensor and heat transfer technology ensure precise temperature regulation that is essential for making consistent, reliable soldering connections. The aluminum alloy housing has advantages of strong structure, good heat sinking, and effective resistance from electromagnetic interference. It provides all the benefits of temperature regulation and connects via a highly flexible burn-resistant Silicone (rubber) lead.
The LF-3300 incorporates electronic circuitry which enables the user to alter tip temperature from 100 to 500°C without changing tips or heating elements. The LCD touchscreen on the front panel provides a user with a clear vision and convenient function setting controls. The temperature is maintained within +/-3° of its operating temperature by a thermocouple sensor placed in the head of the heating element, allowing the tip to rest against the sensor. The 150W/180W high power output results in both a rapid heat-up and super-fast recovery.
The revolutionary “Zero Voltage” electronic switching design also protects voltage and current sensitive components (CMOS devices. etc.) against damaging current and transient voltage spikes commonly produced by less efficient, mechanically switched stations. The power unit is isolated from the A.C. line by a transformer and allows only 36Vac to drive the heating element. The temperature “Lock-out” feature by “password” is convenient for production management. The many features of the LF-3300 make it the ideal tool for service and repair technicians as well as production line soldering operations. This unit is developed to meet the present and future lead-free soldering needs of the electronic production industry and is ideal for use at any AC outlet.

WORKING TEMPERATURE

If you are manufacturing to RoHS requirements, the 60/40 solder alloys are not allowed in the production process. For lead-free solder alloys, a working temperature of 30° higher than leaded electrical soldering is required. The working temperature of lead-free solder is detailed below but can vary from manufacturer to manufacturer.

• Melting point 227°
• Normal operation 300-360°
• Production line operation 360-410°

When the iron’s working temperature is set within the parameters suitable for the type of solder being used, a good joint is assured. Too low a temperature will slow the rate of solder flow while a high-temperature setting might burn the flux in the solder and emit heavy white smoke resulting in a dry joint or permanent damage to the printed circuit board (P.C.8). This may also shorten the tip life.

IMPORTANT: The temperature above 410t is not recommended for normal soldering functions, but can be used for short periods of time when high temperatures are required. Please note that the lead-free solder alloys require a higher soldering temperature which shortens tip life.

Operating Instructions

Ensure that the mains input voltage is between 220-240V before beginning use. Check carefully for any damage during transportation.
This unit contains:

1. Solder handle.
2. Iron holder with brass tip cleaner.
3. AC power cord with plug.

CAUTION: REMEMBER, THE TIP IS HOT. The tip and barrel of the solder handle will cause serious burns if they are allowed to contact the skin. Always return the solder handle to the safety holder after each use. Soldering irons operate at high temperatures and can easily burn people or objects. Do not touch the tip and heater at any time and keep it a safe distance from flammable materials while the unit is on or while it’s cooling. Please allow sufficient time for the unit to cool before changing tips or handles!
DO NOT WORK ON LIVE CIRCUITS. Before working on any mains-powered equipment, make sure that it is turned off, and the mains plug is removed from the PowerPoint.
DO NOT USE IF DAMAGED. If the power lead becomes damaged or the soldering station becomes faulty, discontinue use immediately.

COMMON CAUSES OF TIP UNWITTING

1. Tip temperature higher than 410′.
2. Tip has not been tinned before extended periods of idling.
3. Lack of flux in soldering, wicking, repairing, and touch-up operations.
4. Wiping the tip on a high sulfur content, dirty or dry sponges, and rags.
5. Use organic substances such as plastic, resin, silicone, grease or other chemicals.
6. Impurities in solder and/or low tin content.

CARE OF TIPS

Caution: The soldering iron can reach very high temperatures. Be sure to turn the unit off prior to carrying out any maintenance or troubleshooting steps listed below.
IMPORTANT: Remove the tip and clean after moderate to heavy use or at least daily for light usage. Remove any loose build-up in the tip retaining assembly to prevent tip freezing. The solder tips supplied are iron-clad copper, and if used properly, they should maintain optimum life.

1. Always tin the tip before returning it to the holder, turning off the station, or storing it for long periods of time. Wipe the tip on a brass cleaner prior to use.
2. Keeping the iron set at high temperatures (more than 400°C) will shorten tip life.
3. Do not use excessive pressure on the tip or rub the solder joint with the tip while soldering; this does not improve the heat transfer and may damage the tip.
4. Apply solder to the joint, not the tip when soldering. The flux is naturally caustic and will corrode the tip.
5. Never clean the tip with a file or abrasive material.
6. Do not use fluxes that contain chloride or acid. Use only rosin or resin-activated fluxes.
7. If an oxide film forms on the tip, it can be removed by careful buffing with a 600-800 grit emery cloth, isopropyl alcohol or equivalent and then wrapping rosin core solder around the newly exposed surfaces. Coat the tinned areas with rosin-core solder after the resin-core has melted.

NEW TIPS

Applying the following steps will lead to optimum life.

1. Set the temperature to min. then turn the main power switch to the “ON” position.
2. Set temperature to 250°C.
3. Coat the tinned surfaces with rosin-core solder after reaching 250°C.
4. Set to the desired temperature after allowing the unit to idle at 250°C for 3 minutes.
5. The iron will be ready for use once it reaches the preset temperature.

IMPORTANT: Remove and clean the tip daily. If a new tip is installed, remove any loose build-up in the barrel assembly, otherwise, the tip may fuse to the heating element or retaining barrel.

Maintenance

TIP MAINTENANCE AND DRESSING Tips can be changed or replaced simply by unscrewing the knurled nut barrel assembly. The station must be switched off and allowed to cool before this operation as damage may result if the system is left on without the tip in place! After removing the tip, blow out any oxide dust that may have formed in the tip retaining area of the barrel. Be careful to avoid getting this dust in your eyes. Replace the tip and screw back the knurled nut barrel assembly using only firm hand pressure to tighten. Pliers should only be used to tighten the nut to avoid burning your fingers, but care should be taken not to over-tighten as this could damage the element.

GENERAL CLEANING

The outer cover of the iron and station may be cleaned with a damp cloth using small amounts of liquid detergent. Never submerge the unit in liquid or allow any liquid to enter the case of the station. Never use any solvent to clean the case.

IMPORTANT SERVICE NOTE:

There are no user-serviceable parts inside the unit. Do not open the unit. If the fuse blows, only replace it with an equivalent fuse. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure they do not play with the appliance.

If the iron or station should become faulty or, for some reason not operate normally, the system should be returned to the service department of your authorized dealer or service agent, or a similarly qualified person, in order to avoid a hazard.
