Miller Electric Mfg. Co. has introduced the new Millermatic® 350P aluminum GMAW machine, a dedicated aluminum welding power source with a new true-torque, push-pull motor design; electronic wire spool brake; trigger schedule select; and synergic capabilities in both GMAW and pulsed GMAW settings. The operator can tailor the arc to the weld by adjusting machine performance at the point of use, eliminating trips back and forth to the machine and concerns over wire feed consistency.
The torque motor and the electronic brake work together to provide hours of continuous wire delivery, the manufacturer states. The motor delivers positive, 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 unit automatically adjusts voltage and amperage when the operator adjusts wire speed on the gun. The welder can react in real time to changing joint profiles and positions without having to stop welding and go back to the machine.
