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.
