EXPRESSWELD Inverter 251-ULTRA
, is an inverter welding machine which is manufactured by using the
latest inverter technology and inverter arc welding power units is a technology that has been emerged as of
1980s in international market. 50Hz/60Hz frequency is converted to 20 KHz and higher, in other words to high
frequency by IGBTs, and then alternating current (AC) in converted to direct current (DC) by decreasing the
voltage, in inverter technology a powerful DC welding current is produced by using PWM technique, thanks to
inverter technology, dimensions and weight of the welding machine has been decreased significantly and its
productivity has been increased 30%. Issues like stabile arc creation, safety, lightness and energy saving are
the most important features of welding machines manufactured by using inverter technology. Development of
inverter welding machines is characterized as a revolution in welding field by the experts.
