Running on a 415V ± 10%, 3-phase, 50Hz supply, it's engineered for continuous industrial production environments.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eDrawn arc stud welding creates a full-strength bond by drawing an arc between the stud and base metal before plunging the stud into the molten pool — producing a strong, reliable weld without visible spatter on the surrounding surface. This makes the RDA 2500 well suited to visible or finished applications like architectural lighting, name plates and food service equipment, where weld cleanliness matters as much as strength.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWith a welding current range of 250–2500A and the ability to handle stud diameters from 6–25mm and lengths up to 400mm, the RDA 2500 covers a wide range of stud welding jobs across construction, shipbuilding and heavy fabrication. Welding time is adjustable from 0.01–9.99 seconds, giving operators precise control to match stud size and material thickness. Forced cooling keeps the machine running reliably through sustained industrial use at 107 KVA rated input.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eKey Features\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eDrawn arc type welding for strong, reliable stud attachment\u003c\/li\u003e\n\u003cli\u003eNo weld spatter — suited to visible and finished surfaces\u003c\/li\u003e\n\u003cli\u003eWorks on painted or pre-coated items without damaging the finish\u003c\/li\u003e\n\u003cli\u003eWide welding current range: 250–2500A\u003c\/li\u003e\n\u003cli\u003eHandles stud diameters from 6–25mm, lengths up to 400mm\u003c\/li\u003e\n\u003cli\u003eForced cooling for sustained industrial operation\u003c\/li\u003e\n\u003cli\u003eFast attachment and cost-efficient compared to alternative fastening methods\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: 59.6215%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" style=\"width: 37.0525%;\"\u003e\u003c\/th\u003e\n\u003cth scope=\"col\" style=\"width: 62.6492%;\"\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eRDA 2500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eDrawn arc stud welding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eInput voltage\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e415V ± 10%, 50Hz, 3 Ph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eRated input current\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e162 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eRated input\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e107 KVA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eRated welding voltage\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e32 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003ePower factor\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e0.88\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eWelding current\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e250–2500 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eWeldable stud diameter\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e6–25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eWelding time\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e0.01–9.99 S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eWeldable stud length\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e≤400 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eCooling\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eForced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eProtection grade\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eIP-21S*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eInsulation grade\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eF (typical for this class)*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eDimension (L x W x H)\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003e780 x 355 x 870 mm*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eNet weight\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eTo be confirmed*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.0525%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"width: 62.6492%;\"\u003eRalli Wolf Industries Ltd.
