The Miller Syncrowave 400 Complete Package (951000004) represents the evolution of industrial TIG welding, replacing the legacy Syncrowave 350 LX with a lighter, more energy-efficient inverter-based power source. Designed for heavy-duty fabrication, manufacturing, and maintenance applications, this complete system arrives ready to tackle complex welding tasks on aluminum, stainless steel, and mild steel. The package is built around the Syncrowave 400 power source, which delivers a smooth, stable arc with an amperage range of 5 to 400 amps, ensuring versatility for both thin gauge materials and thick plate welding.
One of the standout features of this machine is the Auto-Link circuit, which automatically links the power source to the primary voltage being applied, whether it is 208V, 240V, or 480V, in either single or three-phase configurations. This eliminates the need for manual linking and simplifies installation in varied shop environments. The integrated Coolmate™ 3S cooling system ensures the included Weldcraft W-375 TIG torch remains cool during high-amperage applications, maximizing duty cycle and consumable life. The cooler features a visual flow indicator, providing operators with immediate confirmation of coolant flow.
For operators, the intuitive user interface is enhanced by Miller's Pro-Set feature. Pro-Set eliminates the guesswork often associated with setting advanced TIG parameters by offering professionally optimized presets for Balance, Frequency, Pulse, and DIG. This allows welders to quickly achieve the speed, convenience, and confidence of expert settings with a single touch. Additionally, the AC Frequency control (adjustable from 50 to 150 Hz) allows for precise tailoring of the arc cone width, improving directional control when welding aluminum. The Blue Lightning™ high-frequency arc starter ensures non-contact, consistent arc initiation every time, reducing tungsten contamination and improving weld quality.
This complete package includes the power source, running gear with cylinder rack, Coolmate 3S cooler, W-375 torch kit, RFCS-14HD wired foot control, coolant, and ground clamp, providing a comprehensive solution for professional fabricators seeking reliability and performance.
