The UNIMIG RAZOR 320 AC/DC TIG Welder (KUMJRRW320ACDC) is a high-end, three-phase powerhouse built for precision fabrication and industrial performance. Designed for professionals who demand the best, this machine delivers superior control, versatility, and weld quality across aluminium, stainless steel, and other demanding materials.
Featuring High-Frequency AC/DC TIG, MIX ARC AC/DC, and Pulse TIG functionality, it gives you complete command over every weld cycle. The multiple AC waveforms (Square, Trapezoidal, and Sine) allow you to fine-tune arc characteristics, bead profile, and penetration. With MIX ARC mode, you can blend AC and DC currents for faster weld speeds, deeper penetration, and cleaner puddle control—ideal for thick or cold workpieces.
Equipped with digital weld sequencing, the RAZOR 320 allows full control over gas timing, slope, and current parameters for ultimate precision. Job memory lets you store and recall up to 50 settings, while Hot Start, Arc Force, and Crater Current features optimise both TIG and Stick (MMA) welding.
The machine supports foot control, water cooler connection, and multiple trigger modes (2T, 4T, 2S, 4S) for unmatched flexibility. Combined with its 43kHz inverter frequency for smooth arcs and ARC TORCHOLOGY T3 TIG torch, you get consistent, professional welds in every application.
Ideal for aluminium fabrication, marine work, stainless steel production, and industrial welding environments, the RAZOR 320 AC/DC is a complete professional solution backed by a 3-year warranty.
