AC TIG Feautures

  • Independent Amplitude / Amperage.
  • Balance Control. Provides adjustable oxide removal which is essential for creating the highest quality aluminum welds. Features extended ranges.
  • Frequency. Controls the width of the arc cone and can improve directional control of the arc.

DC TIG Features

  • Exceptionally Smooth and Precise Arc. For welding exotic materials.
  • AC/DC Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.

AC/DC Stick Features

  • DIG Control. Allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010.
  • Hot Start Adaptive Control. Provides positive arc starts without sticking.
  • AC Frequency Control. Adds stability for smoother welds when AC Stick welding.

AC Waveforms

  • Advanced Squarewave. Fast freezing puddle, deep penetration and fast travel speeds.
  • Soft Squarewave. For a soft buttery arc with maximum puddle control and good wetting action.
  • Sine Wave. For customers that like a traditional arc. Quiet with good wetting.
  • Triangular Wave. Reduces the heat input and is good on thin aluminum. Fast travel speeds.

Lift-Arc Starting

Provides AC or DC arc initiation without the use of high frequency.

Blue Lightening

High-frequency arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability.

Fan-On-Demand

Power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.

Program Memory

Features 9 independent program memories that maintain/save your parameters.

Auto-Postflow

Calculates the length of postflow time based on the Amperage setting. This eliminates the need to independently set the postflow time for different Amperages. This feature preserves your tungsten and prevents porosity.

Sleep Timer

Conserves electricity. This programmable feature will power down the machine if it sits idle for a specified time.

Meter Calibration

Cooler Power Supply (CPS)
