{"product_id":"ralli-wolf-rs25-stud-welding-machine","title":"Ralli Wolf RS25 Digital Drawn Arc Stud Welding Machine – 415V, Dual-Use MMA Rectifier","description":"\u003cp dir=\"ltr\"\u003eThe Ralli Wolf RS25 is a digital drawn arc stud welding machine built specifically for steel structure fabrication, with a dual-purpose design that also functions as a 2500A MMA rectifier for conventional arc welding. That versatility makes it a practical choice for fabrication shops and construction sites that need both stud welding and general arc welding capability without running two separate machines.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eRunning on a 415V ± 10%, 3-phase supply, the RS25 delivers a working current range of 200–2000A with a 60% duty cycle, giving it strong sustained output for structural steel work. It handles stud diameters from Ø10 to Ø25mm, and ships with a stud gun on a 10m cable — long enough to work across large fabrication areas or structural assemblies without repositioning the machine constantly.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAn H-class insulation rating supports reliable performance under sustained thermal load in demanding industrial environments. At 70kg and 830 x 520 x 850mm, it's built as stationary shop or site equipment, mounted on wheels for repositioning between work areas. Standard accessories include the stud gun and an electric welding handle, covering both its stud welding and MMA rectifier functions out of the box.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eKey Features\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eDual-function: drawn arc stud welder and 2500A MMA rectifier in one machine\u003c\/li\u003e\n\u003cli\u003eDigital front panel for precise monitoring and control\u003c\/li\u003e\n\u003cli\u003eStud gun supplied with 10m cable for extended reach\u003c\/li\u003e\n\u003cli\u003eWide working current range: 200–2000A\u003c\/li\u003e\n\u003cli\u003e60% duty cycle for sustained structural welding work\u003c\/li\u003e\n\u003cli\u003eH-class insulation for reliable performance under heavy use\u003c\/li\u003e\n\u003cli\u003eSpecialized for steel structure fabrication\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: 53.056%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" style=\"width: 34.1885%;\"\u003e\u003c\/th\u003e\n\u003cth scope=\"col\" style=\"width: 65.5131%;\"\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003eRS25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eVoltage range\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e3 Ph, 415V ± 10%, 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eRated input power\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e137 KVA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eRated input current\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e190 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eOutput no-load voltage\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e95 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eWorking current range\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e200–2000 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003ePower factor\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e0.88\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eDuty cycle\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e60%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eStud diameter\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003eØ10–Ø25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eInsulation class\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003eH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e70 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eExternal dimensions\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003e830 x 520 x 850 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eStandard accessories\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003eStud gun (10m cable), electric welding handle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 34.1885%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"width: 65.5131%;\"\u003eRalli Wolf Industries Ltd.
