Ever since the foundation of the company back in 1904, as Elektro Svejsning Aktie Bolaget, ESAB, satisfying the needs and demands of our customers has always been our main focus. The company was founded by Oscar Kjellberg, a Swedish engineer and the inventor of the coated welding electrode. His invention revolutionised the manufacture of boilers and ships. Today, in parallel with the development of modern filler metals ESAB has developed welding units that are perfectly matched for just about any process. In addition to modern inverter units there are still robust classics rectifiers.
