IGBT inverter technology gives it excellent line voltage compensation and stepless current control, so weld quality stays consistent even as incoming power fluctuates — a common issue on large industrial sites drawing from shared power infrastructure.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eRunning on a 400V ± 15%, 3-phase supply at 50\/60Hz, the RDA-3100 delivers an output range of 250–3150A, with a rated output of 3150A at an 84% duty cycle — meaning it can sustain near-maximum output for the large majority of a working cycle without overheating, a critical factor for continuous heavy-duty production welding rather than intermittent light use.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt handles stud diameters from ø6mm to ø32mm, covering a wide range of structural and heavy fabrication stud sizes, with weld time adjustable from 0.01 to 4.0 seconds for precise control across different stud sizes and materials. Operator-friendly front panel controls with digital meters make it straightforward to monitor and adjust settings on the shop floor, while a simplified internal circuit design keeps maintenance more manageable than more complex industrial welding systems.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eKey Features\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eIGBT inverter technology with excellent line voltage compensation\u003c\/li\u003e\n\u003cli\u003eStepless current control for consistent, high-quality welds\u003c\/li\u003e\n\u003cli\u003eHigh rated output: 3150A at 84% duty cycle\u003c\/li\u003e\n\u003cli\u003eWide stud diameter range: ø6mm to ø32mm\u003c\/li\u003e\n\u003cli\u003eAdjustable weld time from 0.01 to 4.0 seconds\u003c\/li\u003e\n\u003cli\u003eOperator-friendly front panel with digital meters\u003c\/li\u003e\n\u003cli\u003eSimplified circuit design for easier maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\"\u003eTechnical Specification\u003c\/h2\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable style=\"width: 55.0079%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" style=\"width: 42.8623%;\"\u003e\u003c\/th\u003e\n\u003cth scope=\"col\" style=\"width: 56.5907%;\"\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003eRDA-3100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eInput voltage\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e400V ± 15%, 3 Ph, 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eInput power\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e137 KVA \/ 130 KW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eOutput range\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e250–3150 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eRated output\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e3150A @ 84% duty cycle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eStud diameter\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003eø6–32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eWeld time\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e0.01–4.0 sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eOCV\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e32 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eDimension (L x W x H)\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e840 x 405 x 950 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eApprox. weight\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003e100 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 42.8623%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"width: 56.5907%;\"\u003eRalli Wolf Industries Ltd.
