OVERVIEW

Unlock Precision and Power with the Millermatic 355

Take your welding projects to the next level with the Miller Millermatic 355, the ultimate all-in-one MIG and Pulsed-MIG welding solution. Whether you are working on aluminum boats, stainless steel kitchen equipment, or heavy mild steel fabrication, this machine is built to handle it all with ease. The Millermatic 355 is the first in its class to offer such a comprehensive range of features in a package that weighs only 99 pounds, making it easy to move around your shop or load onto a truck for field work.

One of the standout features for professional welders is the Pulsed-MIG capability. If you've struggled with burn-through on thin gauge aluminum or excessive spatter on steel, the Pulse setting will change the way you weld. It provides a cleaner arc, better puddle control, and significantly reduces post-weld cleanup, saving you time and money on grinding and abrasives. The machine handles material thicknesses from 22 gauge all the way up to 1/2 inch in a single pass, giving you the range needed for diverse jobs.

Miller has made the 355 incredibly easy to use, regardless of your experience level. The large 7-inch color screen is intuitive and easy to read, even in low light. With Auto-Set Elite, you simply select your wire type, diameter, gas mix, and material thickness, and the machine sets the ideal parameters for you. If you prefer to dial it in yourself, the manual mode gives you full control. Plus, with the ability to save your favorite settings, you can return to repeat jobs instantly without guessing.

The package includes the premium Bernard BTB 300-amp MIG gun, known for its comfort and durability. The gun features AccuLock S consumables which ensure the wire feeds smoothly and the arc stays stable. The machine also supports direct connection for push-pull guns or spool guns, making aluminum welding setup a breeze. With the ability to run on almost any voltage found in North America (208-575V), the Millermatic 355 is the versatile workhorse your shop needs.

FAQ

The Millermatic 355 is extremely versatile and can operate on single-phase or three-phase power at 208, 240, 460, or 575 Volts. It features an input voltage selection switch to manually set the correct voltage.

Yes, the Millermatic 355 is excellent for aluminum welding. It features Pulsed-MIG capabilities which are ideal for aluminum, and it supports direct connection of Spoolmatic spool guns or XR push-pull guns.

Pulsed-MIG provides lower heat input, which reduces distortion on thin materials and minimizes spatter. This leads to better weld quality and less time spent on post-weld grinding and cleanup.

Yes, the machine is generator compatible. It requires a generator with at least 19,000 watts (19 kW) of output to operate at full capacity. Smaller generators may result in limited output.

The rated output is 310 Amps at 29.5 Volts with a 60% duty cycle. This applies to both single-phase and three-phase input power configurations.

The machine weighs only 99 lbs (45 kg), which is significantly lighter than its predecessor, the Millermatic 350P, making it much easier to transport.

It includes a 15-foot (4.5 m) 300-amp Bernard BTB MIG gun equipped with Bernard AccuLock S consumables for .035/.045 inch wire.

Yes, it features a 7-inch color LCD display that utilizes Auto-Set Elite to help users quickly and correctly set weld parameters based on material and wire specifications.
