特点：1、电阻对焊机是将两工件端面始终压紧，利用电阻热将接触部分加热至塑性状态，然后迅速施加顶锻压力或不加顶锻压力只保持焊接压力，来完成焊接的方法。2、与闪光对焊相比，电阻对焊操作简单，价格便宜，焊接效率高，焊接后接头光滑，毛刺小。3、结构设计精巧，对精细不一的工件焊接容易调整,专用的对焊机控制电路，确保焊接质量。4、主要用于对焊截面积小于250mm的金属型材，如铁线、板料、管材等。MainPrinciple:1、ACResistanceButtWeldingistheweldingmethodthattheendsurfacesoftwopartsarepressedtightly,andtheresistanceheatisusedtoheatupthesurfacestotheplasticizedstatus,thentheupsettingforcequicklypressthemtogethermoretightagainorwithoutapplyingtheupsettingforcepressure,justonlyholdontheweldingpressuretocompletethewelding.2、ComparedtoFlashButtWelding,ResistanceWeldingismucheasilytoforworkeruseandoperate,thecostismuchlower,weldingproductivityisalsohigher,3、.4、Mainlyusedforbuttweldingvariousmetalmaterialwithweldingsectionarealessthan250mm,suchasiron,wires,pipes,etc.主要技术参数：MainTechnicalParameter:参数Parameter额定容量RatedCapacity额定输入电压RatedInputVoltage额定频率RatedFrequency最大短路电流MaxShortCurrent负载持续率RatedDutyCycle  夹紧力MaxClampingForce  顶锻力MaxUpsettingForce冷却水流量CoolingWaterRequired外形尺寸OverDimensionsL*W*H平均重量AverageWeight型号1-2525KVA380V50/60Hz11000A50%3900N1500N150L/H90*80*120CM300KgTUN1-3535KVA380V50/60Hz15000A50%3900N1500N150L/H90*80*120CM350KgTUN1-5050KVA380V50/60Hz19000A50%3900N1500N150L/H90*80*120CM400KgTUN1-7575KVA380V50/60Hz23500A50%6100N2500N200L/H90*80*120CM450KgTUN1-100100KVA380V50/60Hz26000A50%6100N2500N200L/H90*80*120CM500KgTUN1-150150KVA380V50/60Hz31000A50%8000N3900N300L/H135*80*160CM550KgTUN1-200200KVA380V50/60Hz35000A50%8000N3900N300L/H135*80*160CM650Kg
