Miller Syncrowave® 400 AC/DC

Key Features

• Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.  

• Wind Tunnel Technology™ protects internal electrical components from airborne contaminants, extending the product life. 

•  Coolmate™ 3S cooler (Complete packages only). Three-gallon cooling system equipped with a visual flow indicator ensures that the coolant is flowing. An external coolant filter stops foreign objects from entering the water-cooled torch cable for better flow and longer life. Extended cooling capacity ensures maximum productivity. One-year cooler warranty.  

• Arc timer/cycle counter records actual welding time and number of arc starts. Great for estimating job costs.  

• Welding aluminum? Oxides that form on aluminum melt at temperatures over 3,700 degrees Fahrenheit. The aluminum material that is located under this layer of oxide melts at 1,200 degrees Fahrenheit. The AC squarewave welding current of the Syncrowave 400 auto – matically removes the layer of oxide which is necessary for producing high-quality welds.  

• Do you have power fluctuations? The Syncrowave 400 compensates for power fluctuation without changing your welding parameters. Line voltage compensation works on fluctuating power ±10 percent.  

• Easy-load cylinder rack minimizes cylinder lifting. Cylinder is not included.  

• Lift-Arc™ provides AC or DC arc initiation without the use of high frequency.  

• Blue Lightning™ high-frequency (HF) arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters.  

• Auto-postflow adjusts the length of postflow time based on the amperage setting, shielding your tungsten and eliminating the need to set the postflow time.
