Pulsed GMAW System Optimizes Aluminum Welding

Miller Electric Mfg. Co.’s (Appleton, WI) new aluminum welding system features an enhanced Millermatic 350P all-in-one gas-metal-arc-welding (GMAW)/pulsed GMAW power supply combined with the new XR-Aluma-Pro welding gun. The system provides superior 4000- and 5000-series aluminum feeding and welding performance, according to company officials. It comes with everything necessary to weld aluminum out-of-the-box, including reversible 0.035 to 3⁄64-in. U-groove drive rolls and a Teflon intermediate guide.

The Millermatic 350P includes new pulse programming to meet the specific welding requirements of 4000- and 5000-series aluminum, while providing a more forgiving arc and increased consumable life. When combined with the XR-Aluma-Pro push-pull gun, special calibration software syncs the motor speeds in the gun and power source to provide optimal feeding.

Additionally, an aluminum series-specific tension setting on the XR-Aluma-Pro eliminates wire-feeding problems and erratic arcs caused by an operator setting too much or too little wire tension.
