01 / Overview
Precision in your hands. The pro TIG.
The HORNET 2077 is HELIOS' professional TIG for steel, stainless and aluminium: AC/DC, 200 A and 110/220 V dual voltage, with a 0.99 power factor.
It combines HELIOS' THINK TANK design with the most advanced electronics and an easy yet complete panel, driven by a full-colour TFT display running HELIOS OS 1.5.
It offers several AC waveforms — square and sine — 2T and 4T modes, a spot function, pulsed HF or Lift Arc ignition and compatibility with wired or wireless foot pedals. In MMA it runs every type of electrode.
