EDSYN engineers patented the first temperature controlled soldering instrument in 1971 and trademarked it LONER® because it stood in a class of its own. Decades later and still using this trademark, EDSYN has created a complete line of LONER® soldering instruments, stations and tips to suit your needs. When Selecting the right soldering tool, quality should be top priority as well as ensuring that it genuinely enables technicians and operators to be more efficient and productive. All EDSYN soldering irons and stations are manufactured or assembled in California and backed by an 18 month warranty. All are ESD safe, RoHS compliant and accept a wide variety of tips.
