The Miller Syncrowave 400 offers single or three phase power and features a 30% duty cycle at 400 amps. This machine comes with Auto-Link technology that automatically links the power source to primary voltage being applied (208/240/480). The AC squarewave welding current of the Syncrowave 400 automatically removes the layer of oxide which is necessary for producing high-quality aluminum welds. The Syncrowave 400 compensates for power fluctuation without changing your welding parameters - line voltage compensation works on fluctuating power +-10 percent. Miller's fan-on-demand technology operates the power source only when needed, reducing noise and energy use. The Syncrowave 400 comes with an Arc Timer/Cycle Counter that records actual welding time and number of arc starts, which is great for estimating job costs.
The Syncrowave 400 is easy to use - the intuitive user interface is simple to understand, making it easy to adjust parameters, and means less time training new employees. The Pro-Set button gets to factory preset parameters with one touch of a button. The AC balance control provides adjustable oxide removal which is essential for creating the highest quality aluminum welds, the AC balance can be adjusted from 60-80%, and the Pro-Set is defaulted to 68%.. The Syncrowave 400 comes with Pulsed TIG, which can increase puddle agitation, arc stability, and travel speeds while reducing heat input and distortion. This welder comes with DIG control that allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like 7018, and increase the DIG setting for stiffer, more penetrating electrodes like 6010. The Syncrowave 400 also offers Hot Start which is an adaptive control that provides positive arc starts without sticking.
