951454 - Miller Millermatic 350P Aluminum MIG Welding System with 25ft Aluma-Pro Lite Gun

Industrial Precision for Aluminum Fabrication

The Miller Millermatic 350P Aluminum Package (951454) is a dedicated industrial system engineered to solve the specific challenges of welding aluminum in manufacturing and fabrication environments. At the core of this system is the Millermatic 350P, an inverter-based power source that delivers up to 400 amps of welding output with exceptional arc stability. This specific package is factory-optimized for aluminum applications, pairing the power source with the XR-A Aluma-Pro™ Lite 25-foot push-pull gun. This combination addresses the primary failure point in aluminum MIG welding: wire feeding. The push-pull system ensures consistent wire delivery without buckling or birdnesting, even with soft 4000 and 5000 series alloys.

Technologically, the 350P distinguishes itself with built-in Synergic Pulse capabilities. Unlike standard CV MIG welding, the pulsed output manages heat input more effectively, reducing burn-through on thin sections and allowing for out-of-position welding with spray transfer-like characteristics. The Aluminum Pulse Hot Start™ feature specifically targets the start of the weld, providing a momentary boost in power to break through the oxide layer and establish a puddle immediately, eliminating cold lap defects. The machine supports single- or three-phase input power (200/230/460 V), making it versatile for various facility power configurations.

Operational efficiency is enhanced through the Gun-On-Demand™ feature, which allows operators to keep a second gun connected (such as a standard steel MIG gun) and switch between processes simply by pulling the trigger. The Fan-On-Demand™ cooling system manages thermal regulation intelligently, reducing airborne contaminant intake and lowering noise levels in the shop. For facility managers and industrial engineers, the Millermatic 350P represents a robust, high-duty-cycle solution that minimizes downtime associated with wire feeding issues and maximizes weld quality through advanced waveform control.
