New! Miller Dynasty 300

Experience unfailing precision arc performance paired with a state-of-the-art, user-friendly interface that puts advanced capabilities at your fingertips. Dynasty TIG power sources help minimize error and achieve high-precision welds every time, making the best welders even better.

Features

Easy-to-understand interface with 4.5-inch LCD display

Ensures proper machine setup and parameter selection.
Informative on-screen explanations and dynamic images enhance the parameter selection process.

Program memory

Allows easy naming, saving and recalling of favorite weld settings.
Deliver more productivity by eliminating the need to manually set the parameters.
Deliver consistent quality by welders of all skills.

Pro-set™

Eliminates the guesswork when setting weld parameters.

Locks and limits.

Provides control of weld parameter ranges minimizing deviation from the welding procedure specification (WPS).

Auto-Line™

Allows for any input voltage hookup (120–480 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

Blue Lighning™

Provides more consistent high‑frequency (HF) arc starts and greater reliability compared to traditional arc starters.

USB

Front panel port provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.

Cooler Power Supply (CPS)

Is an integrated 120-volt dedicated-use receptacle for the Coolmate™ 1.3.

Cooler-On-Demand™

Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.

AC TIG Features

alance control provides adjustable oxide removal which is essential for creating the highest quality aluminum welds
Frequency controls the width of the arc cone and can improve directional control of the arc.

AC Waveforms

• Advanced square provides a fast freezing puddle, deep penetration and fast travel speeds.
• Soft square for a soft buttery arc with maximum puddle control and good wetting action.
• Sine for customers that like a traditional arc. Quiet with good wetting.
• Triangular reduces the heat input and is good on thin aluminum. Fast travel speeds.

Independent amplitude/amperage control allows EP and EN amperages
to be set independently to precisely control heat input to the work and electrode

AC/DC Stick Features

DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010.

• Hot Start™ adaptive control provides positive arc starts without sticking.
• AC frequency control adds additional stability when stick welding in AC for smoother welds.
• Stick-Stuck™ detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode. Menu selectable.

DC TIG Features

Exceptionally smooth and precise arc for welding exotic materials.

Pulse Waveforms

• Square provides a fast freezing puddle for ultimate arc control.
• Sine produces a reduced audible sound and provides a more fluid puddle that is good for overlaying applications.
• Triangular provides a quick-forming puddle while further reducing heat for thin materials.
