The Stahl Tools DDSS Digital Display Soldering Station is designed for production soldering that meets the daily demands of the electronics professional. It features a 48 watt ceramic heating element with a 31/2 ft. power cord that can heat up quickly to 400DegreeC.With a superslim ESD safe pencil iron tip that measures 3inch, and a 41/2inch handle, you can work confidently on or around sensitive components. The ceramic ringed stand can be attached to the base or detached if space is limited. Temperature control up/down buttons provide precision heat management. Operating temperature is shown on the 21/4inch x 11/8inch LCD display. Tip Replacement and Dressing: Tip replacement should always be done only when the iron is at room temperature. The tip can be changed or replaced simply by unscrewing the knurled nut from the barrel assembly. The station must be switched off and allowed to cool before and during this operation, as damage may result if the system is left on without the tip installed. 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 debris in your eyes. Replace the tip and screw the retaining knurled nut onto the barrel assembly; tighten only fingertight. Pliers should only be used to tighten the nut if it becomes loose when the iron is hot to, avoid burning your fingers. Care should be taken not to over tighten as this can damage the element. General Cleaning: The outer case of the iron or station may be cleaned with a damp cloth using a small amount of liquid detergent. Never submerse the unit in liquid or allow any liquid to enter the case of the station. Never use solvent to clean the case. Maintenance: The iron must be placed in its stand when not in use. If the supply cord becomes damaged, it must be replaced by a qualified service technician.
