Apex Tool Group - Carl Weller started the Weller Electric Co. in Easton, PA in 1945 with the invention of the soldering gun. He was looking for a way to service the rapidly growing radio repair market. That invention was followed by the first soldering iron in 1950, followed by the first temperature controlled soldering iron in 1976.
Weller expanded into Europe in 1959. Throughout it's history, Weller has continually developed forward looking products for the consumer and industrial markets.

Weller's commitment to technology is evidenced by the seven person R&D team, with numerous patents and awards to their credit.

The Weller University training center in Apex, NC, was established in 2007. Training is provided for over 100 people per year.
