In　order　to　reduce　the　influence　of　polar　zone　effect　in　cross-coupling　arc　by　changing　inter-wire　arc　(IWA)　configuration,　the　influence　of　polarity　arrangement　of　the　IWA　on　droplet　transfer　was　studied.　The　change　of　voltage-current　waveform　and　the　process　of　droplet　transfer　were　recorded　and　analyzed　by　a　high-speed　camera　and　electric　signal　synchronous　acquisition　system.　The　results　show　that　when　the　IWA　polarity　is　arranged　as　anode　on　the　bottom　and　cathode　on　top,　the　anode　spot　force　always　promotes　the　droplet　transfer　and　reduces　the　critical　current　value　of　spray　transfer.　However,　with　the　increase　in　the　input　voltage　of　the　IWA,　the　resistance　of　the　cathode　spot　force　becomes　obvious,　which　hinders　the　droplet　transfer.　While　the　IWA　polarity　is　arranged　as　anode　on　top　and　cathode　on　the　bottom,　increasing　the　input　voltage　of　the　IWA　obviously　reduces　the　plasma　arc　voltage.　The　critical　current　of　spray　transfer　increases　in　anode　droplet,　while　the　cathode　droplet　is　mainly　globular　transfer,　and　there　is　no　spatter　explosion　process.　Through　a　comprehensive　comparison　of　the　droplet　transfer　process　of　anode　and　cathode　under　the　different　IWA　polarity　arrangement,　the　process　of　anode　and　cathode　in　the　IWA　polarity　arrangement　of　the　anode　on　top　and　the　cathode　on　the　bottom　is　more　stable　than　that　in　the　IWA　polarity　arrangement　of　the　anode　on　the　bottom　and　the　cathode　on　top,　mainly　because　the　cathode　spot　force　under　high　current　do　not　hinder　the　cathode　droplet.
