Abstract
In this paper
a set of controlling system of no static difference be used ininverter-type CO2/MAG gas shielded arc-welding machine is desinged
what is adjusted byvoltuge and complex solution to the static characteristic and the dynamic characteristic of theweldiny source is obtained. The maximum short-circuit current is limited
the splashquanlity is reduced
and the welding formation is improved. In this paper
a set of PWMcontrol system driving wire feed that is adjusted no static difference by feedback is designed.For this reason
"the wire drive feed is smooth
accurate and reliable.
