Built around two strings of low internal resistance supercapacitors (3000 Farad) and four high-current MOSFETs, this machine delivers reliable, repeatable welds on demanding packs while keeping costs down.\u003c\/p\u003e \u003cp\u003eUnlike traditional batteries, capacitors store energy and release it quickly, offering instant high-current bursts without memory effects or maintenance headaches. Even after long storage, it remains ready to use. This makes it ideal for building cylindrical monomer packs, mobile phone soft packs, EV battery modules, and repairing power tool packs.\u003c\/p\u003e \u003cp\u003eThe welding pen features a thickened 16-square copper tip with an alumina copper needle, plus a non-stick needle for smooth soldering of 0.2 pure nickel, 0.3 nickel plating, and 0.4 stainless steel joints. The device is designed for bright, clean joints that don’t blacken over time.\u003c\/p\u003e \u003cp\u003eControl and visibility are user-friendly: a single display shows voltage, and you can adjust welding time from 0.5 to 7 seconds and welding power from 1 to 119 levels. The unit supports automatic welding with precise, repeatable results and includes charging controls with constant current and constant voltage charging and capacitor balancing.\u003c\/p\u003e \u003cp\u003eLanguage support is included — hold the power switch for 2 seconds to switch between Chinese and English displays, making it accessible wherever you work.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eAssemble cylindrical monomers and 18650 battery packs for DIY projects with reliable, repeatable welds.\u003c\/li\u003e \u003cli\u003eUse the 0.5–7 second welding window and 1–119 power levels to tailor welds for different nickel thicknesses (0.2–0.3 mm) and materials.\u003c\/li\u003e \u003cli\u003ePerfect for on-the-go repairs or small-batch battery work, delivering strong joints without overheating.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e DWiusty\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eOrigin:\u003c\/b\u003e Mainland China\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eWelding method:\u003c\/b\u003e Capacitor discharge spot welding\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eElectrodes:\u003c\/b\u003e 16-square copper welding pen with alumina copper needle; non-stick needle\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eWelding capabilities:\u003c\/b\u003e 0.3 mm nickel plating, 0.2 mm pure nickel, 0.4 mm stainless steel (joint thickness in mm)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003ePower and drive:\u003c\/b\u003e Four ultra-high current MOSFETs\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eCapacitors:\u003c\/b\u003e Two strings of low internal resistance, 3000 Farad supercapacitors; automatic balancing\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eDisplay:\u003c\/b\u003e Voltage display on a single screen; 2-second language toggle (Chinese\/English)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eControl:\u003c\/b\u003e Automatic welding with adjustable time 0.5–7 seconds; welding power 1–119 levels\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eCharging:\u003c\/b\u003e Constant current\/constant voltage charging with capacitor balancing\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eApplications:\u003c\/b\u003e Suitable for assembling cylindrical monomers, mobile phone soft-pack batteries, electric vehicle batteries, and repairing electric tool batteries\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eDetails not provided.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings \u0026amp; Reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eCapacitors store energy and should be handled with care; ensure proper discharge before maintenance.\u003c\/li\u003e \u003cli\u003eUse the welder for its intended purposes (battery assembly and repair) and follow the user manual for safe operation.\u003c\/li\u003e \u003cli\u003eObserve proper safety precautions when welding and handling energized components.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003ci\u003eProviding quality and trusted service since 2002 at intercyprus.com\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cp\u003ePlease note: All electronic and mechanical equipment, devices and machines sold to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e","brand":"InterCyprus","offers":[{"title":"Black \/ France","offer_id":51470049608022,"sku":"1005008460620076-Black-france","price":148.9,"currency_code":"EUR","in_stock":false},{"title":"Black \/ Poland","offer_id":51470049640790,"sku":"1005008460620076-Black-Poland","price":150.63,"currency_code":"EUR","in_stock":true},{"title":"Black \/ Spain","offer_id":51470049673558,"sku":"1005008460620076-Black-spain","price":148.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Ad3b09e8020654a48bbf448b6f0b4490ej.webp?v=1759506467","url":"https:\/\/www.intercyprus.com\/fr\/products\/0-3mm-nickel-spot-welder-120-gears-adjustable-farad-capacitor-diy-energy-storage-sheet-18650-lithium-battery-welding-equipment","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
