01 / Overview
320 A in AC and DC, water cooled
The HORNET 3277 takes HELIOS AC/DC TIG to industrial level: 320 amps of AC and DC power on a 220 V three-phase supply.
It combines THINK TANK design with the most advanced electronics and an easy yet complete panel. Water cooling allows more continuous working time on the longest shifts.
Several 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 handles electrodes from 1.6 to 6.0 mm.
