Miller Dynasty 400 AC/DC TIG Runner Package

Unleash Your Potential with the Dynasty 400

For professional welders who refuse to compromise on arc quality, the Miller Dynasty 400 TIGRunner is the ultimate weapon of choice. This machine isn't just a power source; it's a precision instrument designed to give you total control over the puddle, whether you are welding thin gauge aluminum or thick steel plate. The TIGRunner package takes the hassle out of setup by mounting the machine and the Coolmate™ 3.5 water cooler on a stable, easy-to-move cart, ensuring your torch stays cool during long, high-amperage runs.

Advanced Waveform Control

The Dynasty 400 puts you in the driver's seat with its advanced AC TIG features. You can manipulate the arc like never before using four distinct waveforms:

• Advance Squarewave: Delivers a fast-freezing puddle for deep penetration and quick travel speeds.
• Soft Squarewave: Provides a buttery, smooth arc with maximum puddle control and excellent wetting action.
• Sine Wave: Mimics the feel of a traditional machine for those who prefer a classic arc.
• Triangular Wave: Reduces heat input, making it perfect for thin aluminum applications.

Independent Amplitude & Pulse

Take your precision to the next level with Independent Amplitude/Amperage Control. This allows you to set Electrode Positive (EP) and Electrode Negative (EN) amperages independently, giving you the ability to precisely control the ratio of cleaning action to heat input. Combined with high-speed DC TIG pulsing (up to 5000 pulses per second), you can reduce heat input, minimize warpage, and increase travel speeds on exotic materials. The Blue Lightning™ high-frequency starter ensures consistent, non-contact starts every time, eliminating tungsten contamination and frustration.

Stick Welding Capability

When the job calls for Stick welding, the Dynasty 400 delivers with tailored arc control (DIG). Whether you are running smooth 7018s or need a stiffer, digging arc for 6010 cellulosic electrodes, the machine adapts to your needs. Hot Start™ adaptive control ensures positive arc starts without sticking, making this machine a true multi-process powerhouse for the serious fabricator.
