951876 - Miller Dynasty 400 AC/DC TIG Welder Package with Wireless Foot Control

Advanced Industrial AC/DC TIG Welding Solution

The Miller Dynasty 400 Wireless Foot Control Package (951876) represents the pinnacle of industrial TIG welding technology, designed for precision fabrication and heavy-duty manufacturing. At its core is the Dynasty 400 power source, a compact yet powerful inverter capable of delivering 400 amps of welding output. This machine is engineered to weld aluminum up to 5/8-inch thick with exceptional control, thanks to its independent amplitude/amperage settings. Operators can set Electrode Positive (EP) and Electrode Negative (EN) amperages independently, allowing for precise management of heat input to the workpiece and the electrode. This level of control is critical for maintaining tungsten integrity while achieving deep penetration on thick materials.

One of the standout features of this system is the Auto-Line™ Power Management Technology. This innovation allows the machine to connect to any input voltage from 208 to 575 V, single- or three-phase, without manual linking. This makes the Dynasty 400 an ideal solution for facilities with dirty or unreliable power, ensuring consistent arc performance regardless of voltage fluctuations. The unit also features advanced AC waveforms, including Advance Squarewave for fast travel speeds, Soft Squarewave for a buttery arc, Sine wave for traditional feel, and Triangular wave for reduced heat input on thin aluminum.

This specific package enhances the operator experience by including Miller's Wireless Foot Control. By removing the control cable, this system eliminates a common trip hazard and reduces cable clutter in the workspace, which is particularly beneficial when working on large weldments. The machine also includes Blue Lightning™ high-frequency arc starting for non-contact ignition, ensuring contamination-free welds. With high-speed DC TIG pulse capabilities up to 5000 pulses per second, the Dynasty 400 provides increased arc stability and reduced heat input, minimizing distortion on exotic materials.
