Issued April 2021 • Index No. AD/4.28 TIG/Stick Welding Power Source Industrial Applications Quick Specs Precision metal fabrication Maintenance and repair Light and heavy manufacturing Shipbuilding Tube and pipe Automotive Vocational TIG (GTAW) Stick (SMAW) DC pulsed TIG (GTAW-P) Max. Open-Circuit Voltage 70 VDC Rated Output 400 A at 26 V, 30% duty cycle 300 A at 22 V, 60% duty cycle Input Power 208/240/480 V, 3-phase or 1-phase power Net Weight Machine only: 131 lb. (59.4 kg) With Cooler and Running Gear: 211 lb. (95.7 kg) Auto-Link® circuit automatically links the power source to primary voltage being applied (208/240/480 V, three- or single-phase). AC TIG Features Balance control provides adjustable oxide removal which is essential for creating the highest quality aluminum welds. Simple to install. Accepts either single- or three-phase input power. Internal cooler power supply runs the Coolmate™ 3S off of the input power and requires no additional hook up. DC TIG Features Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion. Smaller footprint and lightweight design make it easier to install and maneuver. Easy to use. Intuitive user interface is simple to understand making it easy to adjust parameters, and means less time training new employees and more time getting work done. DC Stick Features DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010. Machine only Hot Start™ adaptive control provides positive arc starts without sticking. Pro-Set™ button gets to factory preset parameters with one touch of a button. Complete package Energy efficient. Save on energy costs versus outdated welding equipment. More stable arc and better arc starts versus outdated welding equipment. Power source is warrantied for three years, parts and labor. Equipment Sales US and Canada An ITW Welding Company 1635 West Spencer Street P.O.

Additional Features 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 automatically removes the layer of oxide which is necessary for producing high-quality welds. 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...
