A powerful, compact power source capable of welding up to 5/8" aluminum. Total arc control provides maximum productivity and weld quality while conserving energy compared to traditional welding machines.

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.

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 quiet with good wetting for a traditional arc. Triangular wave reduces the heat input, provides fast travel speeds, and is good on thin aluminum.

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™ is a high-frequency (HF) arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters.
• Includes an integrated 120V dedicated-use receptacle to power the Coolmate™ 3.5. The power switch on the Dynasty also activates the receptacle to help prevent torch failure.
• USB port provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
• LCD display with intuitive interface ensures proper machine setup and parameter selection with informative on-screen explanations and dynamic images.
• Program memory allows easy naming, saving, and recalling of common weld settings.
• Pro-Set (professional settings) feature eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience, and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters.
• Locks and limits provide control of the weld parameter ranges, minimizing deviations from the welding procedure specifications.
• For portability and reliability, Auto-Line™ Technology inverter power supply allows for any single-phase input voltage hookup (208–600 V) with no manual linking.
• Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010. HotStart™ adaptive control provides positive arc starts without sticking.
• Control the width of the arc cone and can improve directional control of the arc with adjustments between 50-150 Hertz.
• QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise.
• Manufacturer's warranty.
