{"product_id":"esccpsw","title":"ECS-S Pneumatic Spot Welder for Cylindrical Cells, ESCCPSW","description":"\u003cp\u003eA Pneumatic Spot Welder is a critical piece of equipment in the assembly of cylindrical battery packs (18650, 21700, etc.). It uses compressed air to drive the welding electrodes downward with consistent, adjustable pressure, ensuring a uniform contact between the battery terminal and the nickel connector (tab). \u003c\/p\u003e\n\u003cp\u003eThe welder uses Resistance Spot Welding (RSW). A high-current pulse is passed through the electrodes, creating localized heat at the interface of the nickel tab and the battery cap. (1) \u003cstrong\u003ePressure Phase\u003c\/strong\u003e: The pneumatic cylinder lowers the electrodes onto the workpiece with a specific force (e.g., 20 N to 100 N). (2) \u003cstrong\u003eCurrent Pulse\u003c\/strong\u003e: The welder releases a millisecond-duration current (often in two pulses: \"Pre-weld\" to clear oxides and \"Main-weld\" to fuse). (3) \u003cstrong\u003eHold Phase\u003c\/strong\u003e: The electrodes remain down for a fraction of a second to allow the weld nugget to solidify. (4) \u003cstrong\u003eRetract\u003c\/strong\u003e: The cylinder lifts, ready for the next spot.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 604.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESCCPSW (ES-CC-PSW)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110 V or AC220V±10%, single phase, 50\/60 Hz, 3 kW\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 184.8px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 184.8px;\"\u003e\n\u003cp\u003e\u003cem\u003eSpot Welding Features\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 184.8px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable Power: 0-99%.
