Idealarc®R3R-400 & 500
Look to the R3R-400 and R3R-500 power sources from
Lincoln Electric for your heavy-duty stick welding needs.
Whether you are using cellulosic, low hydrogen, stainless
steel or hardfacing electrodes, the Idealarc R3R-400 and
R3R-500 produce smooth, quality arcs for consistent
results day-in and day-out.
The R3R-400 and R3R-500 provide peace of mind with
their traditional 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 the roughest
environments. Need to do arc gouging? The R3R-400 and
R3R-500 can help you do that too!

Processes
Advantage Lincoln
• The R3R-400 and R3R-500 produce quality, low spatter, smooth arcs
without pop-outs. Line voltage fluctuations of up to ±10% are handled
by the R3R compensation function to keep the output constant.
• Easy to operate. 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 to conserve
floor space.
• Submersion dipped transformer assembly for added corrosion and
moisture protection.
• Totally enclosed fan motor is permanently lubricated.
• Arc gouging is possible with the R3R-400 with up to 5/16" (7.9mm)
diameter carbon electrode and R3R-500 with up to 3/8" (9.5mm)
diameter carbon electrode.
• Both the R3R-400 and R3R-500 can be used for limited DC TIG
welding – simply add TIG accessories and shielding gas.
• Manufactured under a quality system certified to ISO 9001
requirements and ISO 14001 environmental standards.
• Three-year warranty on parts and labor.
• Seven-year warranty on the power rectifier.
