Miller Electric Mfg. Co. has introduced the first dedicated aluminum welding power source with a new true torque push-pull design, the Millermatic 350P. It also features an electronic wire spool brake, Trigger Schedule Select and synergic capabilities in both MIG and pulsed MIG weld settings.
Consistent aluminum wire delivery is the core feature thanks to the enhanced wire delivery design. The torque motor and the electronic brake work together to provide hours of continuous and productive wire delivery. The new true torque push-pull feed motor provides positive and accurate wire feeding between the torque motor and gun, and the electronic brake allows the wire spool to “free spool” to provide drag-free wire delivery. The new MIG aluminum welder gives the operator the first-of-its-kind flexibility with synergic “one knob” control in both pulsed MIG and MIG operation. This connection means the welder can automatically adjust voltage and amperage when the operator adjusts wire speed on the gun.
The machine is equipped with easy-to-use operator controls, including the new “Trigger Schedule Select”, which permits the user to pre-program two weld settings that they can they quickly toggle between, allowing for quick changes between weld settings or from pulsed to MIG welding. It also prevents costly stop-and-go welding. The new Trigger Hold allows welders to simply press the trigger down and after a few seconds, the gun holds, giving the welder better comfort while working on long weldments. The wire jog feature is a convenient and safe way for the operator to feed wire at the machine without energizing the weld output.
The 350P provides superior aluminum performance when matched with the XR-Aluma-Pro, or the new XR AlumaPro Lite or XRPistol Pro air-cooled push-pull guns. The Millermatic 350P Aluminum’s Hot Start™ eliminates fusion issues by ensuring correct heat from the beginning of the weld. Sharparc gives control of the arc cone shape, puddle fluidity and bead profile while in the Pulsed MIG mode.
