Product DescriptionIntermediate Frequency Inverter DC Spot (Convex) WelderDTB-80  DTB-160  DTB-240  DTB-280  DTB-340  DTB-450Customizable according to requirementsHigh Power ▪ Intermediate Frequency ▪ DC output currentEnergy saving, power saving, high efficiency, low operating cost, and high welding quality.Product overview: The medium frequency inverter DC spot welding machine converts the power frequency (50Hz) AC to the medium frequency (1000Hz) DC output. The time resolution is higher than that of the power frequency, the control accuracy is also improved, and the output current is not affected by the change of the secondary output circuit. It has high thermal efficiency, large output power rate and better welding quality. Compared with the traditional power frequency welding machine, inverter medium frequency DC welding will be efficient and energy-saving. It is a technological revolution breakthrough in the field of resistance welding.Welding material: Aluminum, copper, galvanized sheet, carbon steel, nikel, tungsten and other metal materials.Material thickness for standard machine: < 6.0+6.0mmProcess recommendation: Spot weldingApplication industry: Widely used in welding of metal products in automobile and auto parts manufacturing, new energy power battery, photoelectric communication, Electric light, compressor, hardware, furniture, kitchenware and other industries Product Parameters ParameterDTB-80DTB-160DTB-240  Rated capacity80kVA160kVA240kVA  Input power3 φ 380V3 φ 380V3 φ 380V  Max. short circuit current25KA35KA50KA  Load duration rate20%20%20%  Inverter frequency1000Hz1000Hz1000Hz  Max. pressure6000N6000N12000N  Electrode stroke80mm80mm100mm  Welding ability / Aluminum2.0+2.0 mm2.5+2.5 mm3.0+3.0 mm  Welding ability / Carbon steel2.5+2.5 mm3.0+3.0 mm4.0+4.0 mm  Arm extension size500 × 250mm500 × 250mm500 × 350mm  Electrode arm size¢59 × 173mm¢59 × 173mm¢74 × 195mm  Electrode holder size¢24.6 × 180 mm¢24.6 × 180 mm¢31.6 × 250 mm  Electrode head size¢16 × 50 mm¢16 × 50 mm¢20 × 60 mm  Net weight / Packing weight336kg / 392kg384kg / 440kg733kg / 809kg  Overall dimension / Packing size1180×750×1830mm / 1230X790X1950mm1180×750×1830mm / 1230X790X1950mm1200×870×2070mm / 1230X790X1950mmDetailed PhotosProduct advantages 1. PDKJ MFDC ControllerThe intermediate frequency welding controller and current closed-loop control can control the actual welding current at high speed. The output current is DC, and the current is smooth, the inductance reactance is zero. The working frequency is 1000Hz, and the time control accuracy is 1ms. The welding program can achieve multiple welding functions such as preheating, welding, and tempering to achieve complex welding functions. Humanized design, can save multiple welding presets.  2.LCD touch screenThe interface is simple and beautiful, and the operation is simple. Multi language switching between Chinese and English, with clear welding parameters at a glance. Cooperate with preset functions to achieve fast welding.  3.  Water cooling circulation systemTransparent and intuitive water flow meter for easy observation and adjustment of cooling water flow. PDKJ customized anti-corrosion and anti-aging soft water pipes have a long service life and prevent water leakage accidents. Stable and appropriate temperature can improve welding quality and speed.  4. Thickened and stable body designThe body is designed with a high-strength thickened steel plate mechanical structure, which is stable and rigid, ensuring that the body does not vibrate during welding, and large welded work-pieces do not shake. The high-strength corrosion-resistant nano coating body can ensure machine quality and ultra long service life. And it won the Red Dot, known as the "beautiful spot welder".  5. Pure copper transformerThe transformer of PDKJ is made of pure copper for both primary and secondary poles, with a high conductivity magnetic core and high-quality epoxy resin poured inside. It has good insulation performance and stable performance, and is packaged in a stainless steel shell, with a compact and beautiful appearance. The rectifier component adopts high-power ABB diodes, with stable performance and high efficiency, making it the most reliable heart of PDKJ spot welding machine.  6. Precision and flexible welding platformThe welding platform adopts high conductivity brass material with the copper content of  85%, integrated electrode voltage mechanism, short gas path, compact structure, fast reaction speed, and more convenient installation and maintenance. The stroke between electrodes is adjustable, which can greatly improve the welding speed. Internally, it adopts water-cooled circulation for heat dissipation, and can quickly replace welding fixtures and electrode heads.  7. R&D Pneumatic systemThe seventh generation pressure stabilizing cylinder developed specifically for welding has fast response speed, high pressure resistance, and long service life, meeting the needs of high-speed weldi
