In 2009, Serkay Electronic Welding Manufacturing and Marketing Limited Company was established and started to manufacture high-tech Kuzay inverter welding machine. It gained momentum by adding a single-phase 230 A welding machine to the welding machines it first manufactured as 160 A and 200 A. In 2012, R&D studies of 250 A, 400 A, 600 A Inverter Welding Machines with 380 V input (three phase) were completed and we started mass production. Again in 2012, single-phase group 160A, 200A and 230A Inverter Welding machines were used with generators and mass production was started. In 2014, we started to manufacture inverter welding machines with high voltage protection.
