ESAB introduces Aristo Mig 4004i Pulse power source

The ESAB Aristo Mig 4004i Pulse is a lightweight, multi-process welding power source that can be used for MIG, pulsed MIG, MAG, MMA or TIG welding in applications demanding both high productivity and high quality. The electronically-controlled Aristo Mig 4004i Pulse weighs 70% less than conventional welding equipment and has 70% smaller footprint. The equipment is therefore easier to transport and use in confined spaces. Typical applications include the manufacture of trucks, busses, trailers, off-highway equipment, railway locomotives and rolling stock, as well as wind turbine towers, structural steelwork, shipbuilding/offshore, and general industrial fabrication. To help in achieving high deposition rates, the Aristo Mig 4004i Pulse delivers a welding current of 300 A and voltage of 32 V at a 100% duty cycle. At a 60% duty cycle these figures rise to 400 A and 36 V. The machine operates from a 380-440 V (±10%), three phase supply at 50/60 Hz, and can be powered by a generator when there is no mains supply available. Pre-programmed synergic lines set the optimum welding parameters when welding with different combinations of material, wire and shielding gas. The U6 control panel has a memory to store up to 10 welding schedules while the U82 can store 255. The latter control panel also caters for customised synergic lines. The QSet intelligent welding system automatically fine-tunes the welding parameters 'on the fly' so operatives, even less experienced ones, only have to adjust the wire feed speed to achieve high quality welds. In addition, the LiveTig start function electronically limits the start current, and SuperPulse (available with the U82 control panel) controls the heat input for bridging variable gaps with a spatter-free arc. Creep start, gas pre-flow and hot start functions all help to provide a soft and more direct start with less spatter. TrueArcVoltage (applicable when using a torch from the PSF range) measures the actual arc voltage at the contact tip to ensure welding performance is not adversely influenced by the length of the interconnection cable, return cable or the welding torch assembly. The Aristo Mig 4004i Pulse and associated equipment also reduce operating costs through lower energy consumption. The Cool 1 cooling unit, used in conjunction with water-cooled torches, switches off automatically after 6.5 minutes of inactivity to reduce energy consumption while the equipment is at idle, as do the cooling fans in the power source. Furthermore, the fourth-generation inverter technology achieves a power factor of 0.94, resulting in further energy savings. To complement the Aristo Mig 4004i Pulse power source, ESAB is offering the Aristo Feed 3004 fully enclosed wire feeder. This can be specified with the U6 control panel that has a display, function keys and rotary knobs for voltage and wire feed speed (or current setting), or the U82 control that features a larger display, more controls and far greater functionality – such as the larger memory, SuperPulse capability and customised synergic lines. For less demanding applications, customers can specify the Aristo YardFeed 2000 with the U6 control panel.
