AC and DC TIG Features

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 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.

Blue Lightning™ - High Frequency Arc Starter 

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

120 V Auxiliary Power

The  Dynasty 350 has a 120 V auxiliary power receptacle for the cooling system or small tools.

Stick Features (AC/DC)

Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.
 
Hot Start™ adaptive control provides positive arc starts without sticking.
 
AC frequency control adds additional stability when Stick welding in AC for smoother welds.

AC Waveforms

AC Waveforms
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.

Program memory

Program memory features 9 independent program memories that maintain/save your parameters.

Meter Calibration

Allows meters to be calibrated for certification.

Auto-Line Power Management Technology

Auto-Line Power Management Technology
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.
