400 Amp DC Stick Welding Power Sources

Look to the R3R family of power sources from Lincoln Electric for your heavy-duty stick welding needs. Whether you’re using mild steel, low hydrogen, stainless steel or hardfacing electrodes, the Idealarc® R3R-500-I produces a smooth, quality arc for consistent results day-in and day-out. The R3Rs provide piece of mind with their traditional, fan-cooled design for long life expectancy and low cost operation, calibrated current control knob for simple and easy procedure setting, and all weather protection including a powder paint finish for durability in even the roughest environments. The R3R-500-I is also a proven DC TIG welder – simply add optional TIG accessories and a cylinder of shielding gas.

• The R3Rs produce a quality, low spatter, smooth arc without pop-outs. Line voltage fluctuations of up to ±10% are handled by the R3Rs input compensation function, which keeps the output constant.
• Calibrated current control knob makes procedure setting simple and easy. Polarity switch, voltmeter and ammeter are standard.
• Smooth arc makes it easy to weld with mild steel, low hydrogen, stainless steel and hardfacing electrodes.
• Stackable case design with built-in lift hook allows for easy storage and handling. Machines can be safely stacked three high (without an undercarriage) to conserve floor space.
• Submersion dipped transformer assembly for added corrosion and moisture protection.
• Totally enclosed fan motor is permanently lubricated.
• Designed to NEMA specifications.
• The R3R-500-I is capable of arc gouging using a carbon electrode with a maximum diameter of 5/16" (7.9mm).
• Three year warranty on parts and labor.
  
• Manufactured under a quality system certified to ISO 9001 requirements.
