Product Details Supplier Info More products

The Aristo Mig 4004i Pulse power source from ESAB is a lightweight, multi-process welding power source that can be used for MIG, MAG, MMA or TIG welding in applications that require high productivity and high quality.

These include the manufacture of trucks, buses, trailers, off-highway equipment, trains and railway rolling stock, as well as wind turbine towers, structural steelwork and shipbuilding/offshore structures.

The equipment is light and compact, meaning it is easy to transport and easier to use in confined spaces.

The Aristo Mig 4004i Pulse and associated equipment also reduces 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.

In addition, the fourth-generation inverter technology achieves a power factor of 0.94, resulting in further energy savings.

Further information

  • Aristo Mig 4004i Pulse delivers a welding current of 300A and voltage of 32V at a 100 per cent duty cycle. At a 60 per cent duty cycle, these figures increase to 400A and 36V.
  • The machine operates from a 380–440V (±10 per cent) three-phase supply at 50/60Hz.
  • The machine can be powered by a generator when there is no mains supply available.
  • The Aristo Mig 4004i Pulse connected to the wire feeder’s Aristo Feed 3004 or Aristo Yardfeed 2000 inclusive accessories forms a complete MIG/MAG package.
  • Aristo Feed 3004 is offered with the choice of the U6 or U82 control panels; Aristo Yardfeed 2000 is available with the U6 control panel.
  • The U6 control panel can store up to 10 welding schedules; the U82 can store 255 — this panel also caters for customised synergic lines.
  • Compared with conventional welding equipment, the electronically controlled Aristo Mig 4004i Pulse weighs 70 per cent less and has a footprint that is 70 per cent smaller.
  • The Qset intelligent welding system automatically fine-tunes the welding parameters ‘on the fly’ so the operator only has to adjust the wire-feed speed.
  • The Live Tig start function electronically limits the start current.
  • Superpulse (U82 panel) controls the heat input for bridging variable gaps with a spatter-free arc.
  • Truearcvoltage (applicable when using a torch from the PSF range) measures the actual arc voltage at the contact tip to ensure the welding performance is not adversely influenced by the length of the interconnection cable, return cable or the welding torch assembly.

As part of ESAB, a world leading supplier of welding and cutting solutions, ESAB Group (UK) Ltd have access to a product research and development programme, the envy of the welding industry.

The brand is synonymous with world leading expertise  and today the company produces consumables and equipment for virtually every welding and cutting process and application.

As a logical step following his invention of the covered welding electrode back in 1904, Oscar Kjellberg founded ESAB. Since then, the company has constantly improved on existing methods and materials. At the same time, ESAB has developed new methods to meet the challenge presented by technological progress.

More than 100 years of continuous research, development and manufacture have made ESAB a world leader in welding, cutting and also an international supplier of products, know-how and services that none can match.

At is UK headquarters, ESAB Group (UK) Ltd have a team of highly experienced and qualified staff who are always available to offer help and advice on all aspects of welding and cutting.
