UNITECH 558 + X4

Description

The UNITECH range has been created to simplifying the adjustment of the welding parameters, facilitating the welder’s job. Each function and parameter can be easily managed and configured thanks to the simplified control panel. UNITECH machines are designed to be used in Manual MIG mode. However, ynergic programs can be activated and selected from the front panel. Thanks to the high Duty Cycle and the user-friendly control panel, the HELVI UNITECH range is the perfect replacement for the “old” generation transformer welding machines. Versions with separate feeder are equipped with a new generation wire feeder, whose high precision avoids potential annoying wire jams, making welding even more stable and precise. The innovative “SPEED SPOT” function, available on all HELVI UNITECH versions, guarantees perfect spot welding in MIG mode on any material. The HELVI UNITECH range already complies with the new regulations for Eco Design standards.
