Product Description
The welding machine in this series inverts the 50Hz power supply to a high-
frequency, high-voltage power supply. The inversion process is facilitated by a
powerful IGBT device followed by step-down rectification and pulse-width modulation
(PWM) technology producing a high-power DC output suitable for welding. The
advanced inverter technology allows for the construction of a smaller volume and
light-weight, stable and reliable transformer with a 30% improved efficiency.
Added to the advantages of the inverted power supply, the machine has good
dynamic characteristics, and offers a stable arc, good welding quality and ease of
control.
This semi-automatic, high-performance machine is designed for argon or carbon
dioxide and mixed-gas welding on aluminium, aluminium alloys, low-carbon steel,
