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 (208-460 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 volt 

Also allows single phase or three phase input. Generator friendly. 

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. 

AC and DC TIG pulser control Pulses per second (Hz): AC/DC = 0.1 – 500 PPS 

Memory card port for easy software updates and expansions 

Auto post flow - automatically calculatess the time gas post flow dependant on welding current 

Sleeper timer - conserves enegy by powering down when not in use operator adjustable. 

CPS - Cooler power supply 110v from power source to supply cooler unit. 

Optional feature 

Wireless Remote Control Compatible
