907717 / Dynasty® 400 208-575 V

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 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.

For more consistent non-contact starts and greater reliability compared to traditional HF arc starters.

Allows meters to be calibrated for certification.

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.
