NEW feature on 2023 model onward CV MIG Mode just add a feeder 

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 

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

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