摘要：

A　push　and　pull　feeding　system　with　real-time　control　for　CO2　welding　was　proposed　and　achieved.　It　utilizes　the　motion　controller　to　control　AC　servo　motor　with　the　low　moment　of　inertia,　fast　response,　and　the　buffer　to　connect　the　constant　feeding　part　and　the　push　and　pull　feeding　part.　The　PWM　feeder　speed　control　circuit　with　speed　negative　feedback　by　rotate　coder　was　designed　to　compensate　the　speed　fluctuation　caused　by　the　system　load　and　supply　voltage　changing.　The　push　and　puller　feeding　mechanism　was　designed　to　push　and　pull　the　wire　based　on　the　AC　servo　motor.　According　to　the　characteristics　of　CO2　welding　with　push　and　pull　feeding　system,　the　feeder　speed　curve　is　pre-designed.　The　wire　motion　was　managed　by　the　real-time　control　software　written　in　the　motion　controller.　The　system　has　good　ability　in　anti-jamming　and　stability.　The　highest　feeder　frequency　with　push　and　pull　process　can　reach　90　Hz.
