The Miller Millermatic 355 MIG Welder with EZ-Latch Running Gear (951926) represents a significant leap forward in industrial welding technology, designed specifically for manufacturing, fabrication, and heavy-duty maintenance. This machine is engineered to handle a wide variety of materials with precision, offering standard MIG, Pulsed MIG, and Flux-Cored capabilities in a single, robust package. With an amperage range of 20 to 400 A and a rated output of 310 A at a 60% duty cycle, the Millermatic 355 delivers the power required for thick structural steel while maintaining the finesse needed for thin-gauge aluminum and stainless steel.
One of the standout features of this unit is its integrated Pulsed MIG capability. For industrial fabricators, this means lower heat input, resulting in less distortion on thin materials and significantly reduced spatter. This translates to lower post-weld cleanup times and higher overall productivity. The pulsed arc characteristics also provide better puddle control for out-of-position welding, making it an indispensable tool for complex fabrication jobs involving aluminum or stainless steel.
Flexibility is key in dynamic industrial environments. The Millermatic 355 features an Input Voltage Selection Switch located in the wire drive compartment, allowing operators to manually configure the machine for 208, 240, 460, or 575 V input power on either single- or three-phase lines. This ensures compatibility with virtually any North American power grid. Furthermore, the included EZ-Latch Running Gear revolutionizes shop mobility. The machine secures to the cart via robust latches that can be disengaged without tools, allowing the 99 lb power source to be separated and transported to hard-to-reach areas or loaded into a truck for field applications. It is also fully compatible with generators producing 19,000 watts or more, ensuring full output in remote locations.
The 7-inch color LCD display simplifies complex setups. Features like Auto-Set Elite provide predefined weld settings based on material thickness and wire type, ensuring consistent quality across operators of varying skill levels. The Program Mode allows for the storage and recall of favorite parameters, and the Trigger Program Select feature lets welders cycle through these programs directly from the gun trigger, eliminating unnecessary trips back to the power source.
