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
