OVERVIEW

Industrial Multi-Process MIG Welder for Aluminum Applications

The Miller Millermatic 350P Autobody Package (907300002) is a premier industrial MIG welding solution designed specifically for the automotive repair, fabrication, and manufacturing sectors. This machine distinguishes itself as the first Millermatic to offer compatibility with both single- and three-phase input power, providing exceptional versatility for shops with varying power infrastructure. It supports input voltages of 208V, 220/230/240V, and 460/480V, automatically adjusting to the supplied power.

Engineered for precision, the 350P features advanced Pulsed MIG (GMAW-P) capabilities. This process is critical for welding thin-gauge aluminum, common in modern auto body repair, as it controls heat input to prevent burn-through and distortion while maintaining excellent fusion. The unit offers a wide amperage range of 25 A to 400 A, allowing it to weld materials from 22 gauge up to 1/2 inch thick in a single pass. The rated output stands at a robust 300 Amps at 32 VDC with a 60% duty cycle, ensuring reliability during extended welding sessions.

The Autobody Package is delivered ready for aluminum work. It includes a Bernard Q200 12-foot MIG gun, a spool of Hobart .047-inch 5554 aluminum wire, and U-groove drive rolls. The 5554 alloy wire is harder than standard 4043, allowing for smoother feeding through a standard MIG gun without the immediate need for a spool gun, although the machine is fully compatible with Spoolmatic and XR-series push-pull guns for softer alloys. The integrated running gear and low-mounted cylinder rack provide stability and mobility within the workshop environment.

FAQ

The Millermatic 350P is versatile and can operate on both single-phase and three-phase power. It accepts input voltages of 208V, 220/230/240V, and 460/480V.

No, this specific Autobody Package includes a Bernard Q200 MIG gun and is set up to push harder aluminum wires (like the included 5554 alloy). However, it is directly compatible with Miller Spoolmatic 15A/30A spool guns and XR-series push-pull guns if needed for softer wires.

The machine has a rated output of 300 Amps at 32 VDC with a 60% duty cycle, meaning it can weld at 300 amps for 6 minutes out of a 10-minute period without overheating.

The Millermatic 350P can weld mild steel up to 1/2 inch (13 mm) thick and aluminum up to 3/8 inch (9.5 mm) thick in a single pass.

The Bernard Q200 gun uses the #N-5800C screw-type copper nozzle with a 5/8-inch (15.9 mm) orifice flush.

Yes, the machine comes with a factory-installed, low-mounted running gear that includes a cylinder rack. A dual cylinder rack (part #195299) is also available as an optional accessory.

It can handle solid steel wire from .023 to .045 inches, stainless from .030 to .045 inches, and aluminum from .035 to .047 inches.

Pulsed MIG allows for welding at lower average heat inputs, which is crucial for thin automotive sheet metal (especially aluminum) to prevent burn-through and minimize warping while ensuring strong penetration.
