Features

  • Intuitive Interface LCD Display
  • Ensure proper machine setup and parameter selection with informative on-screen explanations and dynamic images.
  • AC TIG Features Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode.
  • Extended AC balance controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.
  • AC frequency (20 400 hz) controls the width of the arc cone and the force of the arc.
  • DC TIG Features Exceptionally smooth and precise arc for welding exotic materials.
  • High-speed DC TIG pulse controls - Pulse frequency capable of pulsing 5000 pulses per second.
  • Pulsing adds arc stability, reduces heat input and warpage and can increase travel speeds. Other parameters include peak amperage, peak time and background amperage.
  • Advance Squarewave provides a fast freezing puddle, deep penetration, and fast travel speeds.
  • Soft Squarewave is used for a soft buttery arc with maximum puddle control and good wetting action.
  • Sine wave is for customers that like a traditional arc. It is quiet with good wetting.
  • Triangular wave reduces the heat input and is good on thin aluminum. It provides fast travel speeds.
  • QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise.
  • High-frequency (HF) arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters.
  • Control the width of the arc cone and can improve directional control of the arc with adjustments between 50-150 Hertz.
  • This feature eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse and DIG

Choice of AC waveforms to suit your job : 

Advance Squarewave provides a fast freezing puddle, deep penetration, and fast travel speeds. 

Soft Squarewave is used for a soft buttery arc with maximum puddle control and good wetting action. 

Sine wave is for customers that like a traditional arc. It is quiet with good wetting. 

Triangular wave reduces the heat input and is good on thin aluminum. It provides fast travel speeds. 

Blue Lightning™ - High Frequency Arc Starter 

For TIG non-contact arc initiation. Provides more consistent arc starts and greater reliability 

Compared to traditional HF arc starters. Easy to set up and increases productivity. 

Auto-Line Power Management Technology 

Allows for any input voltage hookup (210-575 V) with no manual linking, providing convenience in any 

In any job setting. Ideal solution for dirty or unreliable power. Multi voltage input 240/415 v 

AC and DC TIG Features 

Extended AC balance (30-99%) controls the amount of oxide cleaning (amperage time in EN) which is 

Essential for high quality welds on aluminum. 

AC frequency (20-250 hz) controls the width of the arc cone and the force of the arc. 

Increasing the AC Frequency provides a more focused arc with increased directional control. 

Independent AC Amperage Control 

Allows the EN and EP amperage values to be set independently. Adjusts the ratio of EN to 

EP amperage to precisely control heat input to the work and the electrode. EN amperage 

Controls the level of penetration, while EP amperage dramatically effects the arc cleaning 

Action along with the AC Balance control. 

AC and DC TIG pulser control 

Pulses per second (Hz): DC = 0.1 – 5000 PPS / AC = 0.1 – 500 PPS 

Optional feature 

Wireless Remote Control Compatible 

Improve productivity, eliminate clutter and cord tangles in the work area. Prevent cord failure 

And associated downtime/repair costs and extend the operator's welding range without adding 

Cable extentions 

Dimensions Weight 61 kg. H=629 w=349 d=559mm 

Welding Mode TIG output 

400 A 20% duty cycle 

350 A 30% duty cycle
