Inverter welder for arc welding

Inverter welders are technologically advanced products designed for arc welding with a coated electrode (MMA method).Inverter welders are a new type of welder, generating the necessary current values using electronic systems.They are characterized by small dimensions, low weight, considerable efficiency, wide range of applications, very good welding effects and transport mobility. Welding machine model: DESi155BT is designed for manual welding with coated electrodes of such materials as alloy steel, construction and cast iron.It can be used using electrodes with diameters from 1.6 mm to 3.25 mm, depending on the specified welding current, needs and the type of operations performed.The welders are adapted to a power supply with a voltage of 230V 50 Hz (single-phase).IGBT transistors are used in its construction.Insulated Gate Bipolar Transistor) - a bipolar transistor with an isolated input.It is a semiconductor power element used in power converters.It combines the advantages of two types of transistors: ease of operation of pole transistors and high breakdown voltage and switching speed of bipolar transistors.The use of IGBTs in a welder causes the device to achieve high efficiency at small size and low weight compared to welders with power circuits based on other technologies.The welder can be used with a TIG Lift cable, enabling welding using the non-melting electrode method (TIG, LIFT).
