Intermediate-Frequency Inverse DC Spot (projection) Welding Machine Mfdc Welder

Intermediate-frequency Inverse DC spot (projection) welding machine
• The direct pressure mechanism has good servo performance and fast welding speed: the guiding part adopts special material with small friction foce, and the electromagnetic valve and cylinder connect directly to speed the action speed, improve the beating speed, and reduce the loss of air flow.
• The service life is long and the noise is small. With the adjustment function of pressure speed, the upper and descending speed of the pressure head can be adjusted arbitrarily, and the impact the welds is reduced. With the function of rising buffer, it can adjust the ascending and buffering speed arbitrarily, reduce the mechanical impact and improve the service life of the cylinder block, and also reduce the noise.
• Safe and easy to use: high performance gas circuit filter cup with a shield, can prevent the glass breakage deb is splash, and also Protect the impact from the impact from the external. Cups and shields can be handled and easily overhauled.
• High quality and high efficiency welding power, power factor up to 98%, three phase input load balacing, and the impact on user power grid is greatly reduced.
• The output current of DC current, smoothing, zero reactance. The woking frequency and time control accuracy of 1000Hz are 1ms.
• The fuselage is designed with high quality steel plate and optimized mechanical structue, which is beautiful and rigid, ensuing stable welding quality.
• The electrode voltage mechanism is integrated, the gas path is short,the stuctuer is compact, the reaction speed is quicker,installation and maintenaice are more convenient.
• The seconde circuit uses high quality conductive materials, which greatly reduces the impedance of the circuit.
• The cylinder reversing valve adopts imported well-known brand, which has fast response speed, large flow rate and long service life, and is suitable for high-speed rush request.
• The standard components adopt the international brand, so that the overall quality of the welder reaches the first class level.
• Equipped with intermediate frequency soldering controller and current closed loop control, it can control the actual welding current at high speed and accurancy.
• Can store 60 sets of welding specifications, large screen LCD screen interface, with Chinese and English switch display.
• Widely used in aerospace, automobile and automobile parts manufacturing, new energy and power battery ad other special areas of high quality welding requirements.Customer CaseTechnical ParametersModelDTB-80DTB-160DTB-240Rated capacity80KVA160KVA240KVAInput power supply3Φ380V3Φ380V3Φ380VInverting frequency1000HZ1000HZ1000HZMaximum short circuit current25000A35000A5000ALoad sustainability20%20%20%Inverting frequency1000HZ100HZ1000HZArm extension500*250mm500*250mm450*350mmMaximum pressure6000N6000N10000NElectrode stroke60mm60mm60mmCooling water flow12L/min12L/min12L/minWeldability/aluminum plate2.0+2.0mm3.0+3.0mm4.0+4.0mmWeldability/gavanized sheet1.5+1.5mm2.5+2.5mm3.5+3.5mmWeight(kg)350390580Overall size(mm)1105*670*17201105*670*17201180*910*2140
