951000005 - Miller Dynasty 400 Complete TIG Runner Package with Foot Control

Precision AC/DC TIG Welding Solution

The Miller Dynasty 400 Complete Package (951000005) represents the pinnacle of industrial TIG welding technology, designed for professional fabricators who demand absolute control over their arc. This comprehensive package combines the powerful Dynasty 400 power source with the essential components needed for high-amperage, water-cooled applications, including the Coolmate™ 3.5 cooler, a rugged runner cart, and a remote foot control for precision amperage adjustment.

Advanced Auto-Line™ Technology

One of the standout features of the Dynasty 400 is Miller's proprietary Auto-Line™ Power Management Technology. This innovation allows the machine to connect to any input voltage within the 208V to 575V range, single or three-phase, without manual linking. This makes the Dynasty 400 an ideal solution for facilities with "dirty" or unreliable power, as it maintains a steady arc even when input power fluctuates. It ensures that your welding parameters remain consistent, reducing rework and improving overall productivity.

Superior Aluminum Welding Performance

For aluminum welding, the Dynasty 400 is unmatched. It features Independent Amplitude/Amperage Control, allowing operators to set Electrode Positive (EP) and Electrode Negative (EN) amperages independently. This capability provides precise control over heat input to the workpiece and the electrode. Additionally, the extended AC Balance (30–99%) controls the amount of oxide cleaning, while AC Frequency (20–400 Hz) allows you to tailor the width and force of the arc cone. Whether you need a soft, buttery arc for thin materials or a focused, driving arc for thick plate, the Dynasty 400 delivers.

Complete Water-Cooled Package

This "Complete" SKU is designed to get you up and running immediately. It includes the Coolmate™ 3.5, powered directly by the Dynasty's integrated Cooler Power Supply (CPS). The CPS is a dedicated 120-volt receptacle on the machine that activates the cooler only when the welder is on, preventing torch failure due to lack of coolant flow. The included runner cart provides mobility for the entire setup, holding the cylinder, machine, and cooler securely.

Waveform Versatility

The machine offers four distinct AC waveforms to suit various applications:

• Advanced Squarewave: Fast freezing puddle, deep penetration, and fast travel speeds.
• Soft Squarewave: A buttery arc with maximum puddle control and good wetting action.
• Sine Wave: Traditional, quiet arc with good wetting.
• Triangular Wave: Reduces heat input, ideal for thin aluminum.
