Lincoln Electric Idealarc R3R-400 Stick Welder - 230/460V

The R3R-400 covers 60 to 500 amps, handling everything from light maintenance stick welding at 60A to heavy structural welding and carbon arc gouging at 500A. The calibrated control knob makes procedure setting simple and repeatable. The voltmeter and ammeter on the front panel confirm actual welding parameters.

Yes. The R3R-400 handles carbon arc gouging with electrodes up to 5/16 inch (7.9 mm) diameter. The 500A maximum output provides the sustained amperage that gouging demands. This eliminates the need for a separate gouging power source in shops that do both heavy stick welding and groove preparation by gouging.

The smooth arc characteristic works with mild steel, low hydrogen (7018), cellulosic (6010/6011), stainless steel, and hard facing electrodes. The polarity switch and wide amperage range accommodate the specific requirements of each electrode type without compromising arc stability or weld quality on any of them.

Yes. The stackable case design with built-in lift hook allows machines to be safely stacked three high to conserve floor space. The lift hook also simplifies crane or forklift handling when moving the machine in and out of the shop. This is practical for rental fleets and large fabrication shops with multiple units.
