Designed for ease of use and high performance, this all-in-one welder handles MIG, Stick, and DC TIG processes with professional precision. Whether you are welding mild steel, stainless steel, or aluminum, the Multimatic 255 delivers a smooth, stable arc. The included MDX-250 MIG gun features the AccuLock S consumable system, which ensures flawless wire feeding and superior arc performance, reducing downtime and operator fatigue.

Intuitive 7-Inch LCD Display

Gone are the days of guessing your settings. The Multimatic 255 features a vibrant 7-inch color LCD screen that guides you through the setup process. The Auto-Set Elite technology eliminates the guesswork by providing optimal settings based on your material and gas type. This feature is perfect for welders of all skill levels, ensuring that the job is done right the first time. For those who prefer manual control, the machine offers full adjustability and a Program Mode to save your favorite settings for instant recall.

Built for Mobility and Efficiency

Weighing only 84 lbs, the Multimatic 255 is designed for portability. The inverter technology not only reduces weight but also improves energy efficiency. The machine is compatible with the optional EZ-Latch running gear (sold separately), which allows for quick detachment of the power source from the cart, making it easy to load into a truck or move around the shop. The Auto-Gun Detect feature automatically adjusts voltage and wire speed when switching between the standard MIG gun and an optional spool gun or push-pull gun.

Complete Welding Solution

This package includes everything you need to start MIG and Stick welding immediately. It comes with the power source, a 15-foot MDX-250 MIG gun, a 10-foot cable with electrode holder, a 10-foot work cable with clamp, a flow gauge regulator with gas hose, and reversible drive rolls. With its ability to run 6010 stick electrodes and its direct connection for push-pull guns, the Multimatic 255 is a versatile workhorse ready for any challenge in the shop or field.
