A range of soldering irons to meet most applications. From electronics work to automotive repair work. Hints for long tip life: Periodically remove and clean the tip and barrel junction to maintain good heat transfer. Never file a tip clean – whilst still hot. simply wipe over with a damp sponge or rag to remove any residue. Filing should only be done as a last resort. Also limit the use of solders with acids by cleaning the job before soldering. Use crimp type connections where possible as they are superior to solder types and far more efficient to use.
