TIG Welding Equipments

Heliarc 252-352 AC DC

MMAW/TIG Power Source

Tig Welding (GTAW) with high frequency starts Stick Welding (SMAW) with variable arc force.

Special Features

  • Output current range from 5 to 320 amps.
  • Square wave AC output gives superior welding with improved cleaning and lack of rectification.
  • AC wave balance control-adjust from maximum cleaning to maximum penetration.
  • Arc control fine-tunes the arc for stick welding from a soft arc to a high penetration, digging arc.
  • A choice of AC, DCSP or DCRP welding current with a simple turn of the polarity selector switch.
  • Adjustable preflow and post flow gas control protects the weld area and extends tungsten life.
  • 100% solid-state design - no mechanical contactor; no output drift - long life with low maintenance.
  • Modular design - easy to upgrade as per requirement.
