Case

The robot cell was 100 per cent accurate at the first go, and the finish of the large batches of welds is now beautiful and uniform. Migatronic’s high-tech power source is very efficient and powerful. It features a pulse function and intelligent gas control, which reduces weld spatter as well as gas consumption. All things considered, the robot cell has significantly reduced our production time and costs
