Accupocket brochure - .PDF file.

Fronius has introduced the Accupocket 150/400, a portable welding unit that is powered by built-in lithium-ion rechargeable batteries for off-grid use. Applications include repair welding or site-erection work in remote terrain where there is no direct access to mains electricity.

The unit is designed for convenient mobile manual electrode and TIG welding and can be used in electrically high-risk environments in battery mode because its internal design structure ensures that the highest voltage occurring anywhere inside it is always far below the permissible maximum of 113VDC.

A fully charged battery (400Wh) delivers sufficient power to weld up to eight 3.25mm-diameter electrodes or 18 2.5mm-diameter electrodes.

The rechargeable battery delivers rated energy of nearly 400Wh while only weighing 5.25kg.

Even when attached to the Activecharger, Accupocket can still be used to carry on working, in hybrid mode. During run-times, the energy from the battery is used to ensure a constant arc under all operating conditions (for example, mains-voltage fluctuations). The welding off-times are then used for recharging the battery.

The battery exercises a buffering function that lessens the load on the supply network, in turn preventing the annoyance of circuit-breakers being tripped on jobsites. In addition, the full welding amperage of 150A is available in TIG mode, or 140A in MMA mode, even in a 110V network.

Accupocket can also be run from very small generators. In this case, the integrated rechargeable battery reduces the required maximum power input, meaning that a much lower-capacity source can be used — instead of an 8kV generator, a 2kV one is now sufficient.

Thanks to its facility for battery-powered operation, Accupocket minimises time-consuming weld preparation work. This means that in many applications, Fronius states that it is actually more economical, over its service life as a whole, than conventional electrode welding systems.

Key product features

  • Low weight and compact dimensions: 11kg; 435 x 160 x 320mm
  • Activecharger device supplied with the Accupocket is based on Fronius’s Active Inverter Technology and is specially tailored to the requirements of the welding unit
  • Intelligent control system using Accuboost technology makes sure that the battery and the welding electronics work together perfectly, regularly meaning better welding results than could be obtained with a comparable mains-only-powered MMA welding unit
  • The rechargeable batteries (lithium-iron-phosphate, LiFePO4) used in Accupocket offer high intrinsic safety and environmental compatibility, lower self-discharge and no memory effect
