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 (30–99%) controls the amount of oxide cleaning (amperage time in EP) 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.

Allows for any input voltage hookup (208–575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
Lift-Arc™ start provides AC or DC arc starting without the use of high frequency
Blue Lightning™ high-frequency arc starter for more consistent non-contact starts and greater reliability compared to traditional HF arc starters.
Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.
