Pulsed-MIG Advantage

  • Whether welding aluminum, steel or stainless steel, improving productivity by 30, 50 or 100% and saving tens of thousands of dollars are typical results when switching to Pulsed-MIG with the Millermatic 350P.


  • Optimizes the size and shape of the arc cone, bead width and appearance and puddle fluidity.

Millermatic 350P Autobody Aluminum Package

  • The automotive industry is trending to aluminum frames and body panels to improve performance and fuel mileage. Welding thin gauge aluminum creates problems with warping, distortion and burn through. The Millermatic 350P Autobody Aluminum Package makes it easy to setup, use and make quality aluminum repairs.

Aluminum Pulse Hot Start

  • Automatically provides more arc power to eliminate a “cold start” that is inherent with aluminum starts.


  • The Fan-On-Demand Cooling system only operates when needed, reducing power consumption and keeping internal components cleaner.

Line Voltage Compensation (LVC)

  • Line Voltage Compensation keeps output of the power source constant regardless of fluctuation in input power ± 10%.


  • Miller’s Gun-On-Demand feature allows you to use either a standard MIG gun, a Spoolmatic 15/30A spool gun or any other Miller push-pull gun without flipping a switch. The machine senses which gun you are using when you pull the trigger.
