Few years later, they released to the market a soldering iron on with self-adjusting temperature. In 1951, the company WEN Products began manufacturing its own instantaneous soldering iron. After a three years trial Weller won for patent infringement. [11] In 1960 Weller got the patent for the soldering iron "Magnastat", renewed in 1964 and ...
A soldering station is a multipurpose power soldering device designed for electronic components soldering. This type of equipment is mostly used in electronics and electrical engineering . Soldering station consists of one or more soldering tools connected to the main unit, which includes the controls (temperature adjustment), means of ...
This gene encodes a subunit of the cytokine Interleukin 12 (IL-12) that acts on T and natural killer cells, and has a broad array of biological activities.The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family.
A 1948 advertisement for a Weller soldering gun. Pistol-grip electrically-heated soldering tools had been used since the 1920s. In 1941 Carl E. Weller invented and later obtained U.S. patent 2,405,866 [1] for a transformer-based soldering tool which heated and cooled rapidly, [2] essentially as described in this article.
A 100-watt soldering iron may provide too much heat for printed circuit boards (PCBs), while a 25-watt iron will not provide enough heat for large electrical connectors. Using a tool with too high a temperature can damage sensitive components, but protracted heating by a tool that is too cool or under powered can also cause heat damage.
The split tip of a ColdHeat soldering iron. The first two products were soldering irons powered by alkaline batteries.The manufacturer claims this soldering iron is unique in that its Athalite tip undergoes a temperature change from ambient temperature to approximately 800 °F (427 °C) and back to ambient within three seconds when the tip is removed from the work.
