Simplified TIG welding for tube and pipe fabrication and maintenance

from 5 to 230A DC and 15 to 230A AC (maximum output of 230A at 30 per cent duty cycle) and a maximum MMA output of 180A at 30 per cent duty cycle for welding with electrodes up to 4mm. It connects to 115/230V AC mains power and meets the EU’s Ecodesign Directives for energy efficiency. The Rogue ET 230i is effective for welding aluminium because it provides four AC waveshape options: square wave for maximum arc stability and energy transfer, soft square for a softer arc and more fluid puddle, sinusoidal for a quieter and traditional arc and triangle for reduced heat input on thinner material. To further tailor the wave form to the application, the machine also offers an amperage offset that is adjustable ± 50 amps in each half of the AC cycle.

TO enable intuitive control over the variables that optimise TIG welding performance, ESAB has introduced the Rogue™ ET 230i AC/DC TIG and MMA welder, which features ESAB’s signature 5” colour TFT graphical interface. The Rogue ET 230i provides useful controls for welding, including pulse AC and DC TIG, an adjustable AC output frequency, AC amplitude offset, a TIG sequencer, four AC waveshape options and an optional water-cooler and water-cooled TIG torch. “The Rogue 230i provides operators more control over heat input, penetration, puddle direction, bead appearance and weld quality without the typical complexities associated with setting TIG variables,” said Bartosz Kutarba, global director, light industrial equipment, ESAB. “No other machine on the market can match Rogue’s combination of intuitive operation, range of control and

affordability. It is an ideal machine for both experienced and newer welders.” With Lift TIG and high frequency (HF) arc starting options, it enables users to weld stainless steel, aluminium and other metals in a wide range of applications, including general fabrication, process industries, tube and pipe fabrication, repair and maintenance and aerospace. For optimised arc starts, users enter the tungsten type and diameter and the machine will automatically set parameters. The Rogue 230i ET AC/DC has a TIG welding amperage adjustable
