Castolin Eutectic has recently launched two new last-generation arc welding machines (MMA) across Europe: ACCUmax, the new portable power source running on high capacity lithium-ion battery, and POWERmax 4.0 at 150A, with the POWERmax 1800 alternative at 180A.
With the new AccuMax, cable-less mobile welding on top of mountains, in difficult-access areas, on farming land or construction sites is now possible. The lightweight small MMA welding machine does not require mains electricity. With a fully charged battery, welding work can be autonomously performed for up to 6 electrodes of 3.25 mm diameter and up to 18 electrodes of 2.5 mm diameter. ACCUmax is also fit for welding in electrically hazardous areas, such as boiler welding, container construction, shipbuilding.
With reduced weight and compact size for versatile on-site handling, PowerMax 4.0 makes welding easier via an innovative resonance principle: the quick reacting characteristic curve control of the unit means the welding result is improved even with demanding manual electrodes. The digital resonance inverter ensures an extremely stable arc, as well as reduced spatter formation. In addition, by adapting the power consumption to the network voltage, the losses (inductive and capacitive reactance effects) are reduced and the energy-efficiency improved. The Power Factor Correction enables energy savings and extended mains cables up to approx. 100 m, as well as a more flexible input voltage range.
