Miller Syncrowave 400 AC/DC TIG and Stick Welder (907783)

Miller Syncrowave 400 AC/DC TIG and Stick Welder (907783) 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.
