CO2 GTAW/MIG/MAG welding machine development

Sep 2011 - Feb 2012 (5 months)

The 220V/380V ac input is rectified to get high voltage DC source for feeding welder sufficient power. This DC high voltage will be step down to 20~40V DC output which is the range of voltage used in MIG welding.

CVCF Device development

Oct 2005 - Apr 2006 (6 months)

The input voltage range is 110~230V and the input frequency range is 30~55Hz. The output is stayed in constant voltage 220V and the frequency is remained as 50Hz. The modern inverter technology is used in CVCF.
