MMA Welding Unit For Mobile Welding

Fronius has launched a battery-powered MMA Welding Unit for convenient mobile welding. The AccuPocket 150/400 is said to be the world’s first-ever MMA welding system with a high-performing lithium-ion rechargeable battery and a low overall weight of only 11 kg, giving users unprecedented freedom of movement in manual electrode and TIG welding. A fully charged battery (400 Wh) delivers sufficient power to weld up to eight 3.25 mm diameter electrodes or 18 electrodes of dia 2.5 mm. The ActiveCharger device supplied with the AccuPocket is specially tailored to the requirements of the welding unit, and is based on Fronius’ proven Active Inverter Technology. An intelligent control system using AccuBoost Technology makes sure that the battery and the welding electronics work together perfectly. In practice, this regularly means better welding results than could be obtained with a comparable mains-only powered MMA welding unit. Compared to conventional lithium-ion batteries, the rechargeable batteries used in the AccuPocket (lithium-iron-phosphate, LiFePO4) stand out for having the highest intrinsic safety and environmental compatibility currently available, lower self-discharge and no memory-effect. Built-in battery-management functions and the specially adapted external ActiveCharger – with Active Inverter Technology that detects the state of the battery and optimally adapts the charging characteristic – together ensure safe operation and long battery-cell life. Although it weighs only 5.25 kg, the rechargeable battery delivers rated energy of nearly 400 Wh. Together with the unit’s compact dimensions (435 x 160 x 320 mm) and sturdy constructional design, this makes AccuPocket the ideal solution for repair welding or site-erection work in remote terrain where there is no direct access to mains electricity. Fronius India Private Ltd has a state-of-the-art technical support centre – including all kind of power sources as well as robots – in Pune. The company provides best support for welding trials with its highly qualified service and application engineers.
