951873 - Miller Syncrowave 400 AC/DC TIG Welder Package with Wireless Pedal

Industrial AC/DC TIG Welding Solution

The Miller Syncrowave 400 Complete Package (951873) represents a modern evolution in industrial TIG welding, replacing the legendary Syncrowave 350 LX with a lighter, more energy-efficient inverter-based platform. Designed for precision metal fabrication, heavy manufacturing, and maintenance applications, this system delivers up to 400 amps of welding power while reducing energy costs by up to 33% compared to traditional transformer-rectifier machines. This specific package is the "Complete" edition, factory-equipped with the Miller Wireless Foot Control, providing operators with untethered freedom and reducing cable clutter on the shop floor.

At the core of the Syncrowave 400 is Miller's Auto-Link technology, which automatically detects and adjusts to the primary input voltage—whether 208V, 240V, or 480V, single or three-phase—eliminating the need for manual linking and reducing installation errors. The machine features advanced Squarewave technology with adjustable AC Balance (60-80%) and AC Frequency (50-150 Hz), allowing for precise control over cleaning action and arc cone width when welding aluminum. The integrated Coolmate 3S water cooler ensures consistent torch performance during high-amperage applications, featuring a visual flow indicator and an external coolant filter to protect the torch cable.

The user interface is streamlined for efficiency. The Pro-Set feature allows operators to bypass complex setup procedures by selecting preset parameters for Balance, Frequency, Pulse, and DIG, ensuring professional results with minimal downtime. For Stick welding, the machine includes DIG control to tailor arc characteristics for specific electrodes, such as E6010 or E7018. This package includes the power source, Coolmate 3S, running gear, wireless foot control, Weldcraft W-375 torch, and all necessary coolant and cables, making it a turnkey solution for high-performance fabrication.
