The Millermatic 211 PRO is a compact yet powerful inverter welder that brings real versatility to both hobby shops and professional garages. Designed with dual-voltage capability (120/240 V), this machine easily adapts to common power sources, making it ideal for mobile jobs or fixed shop settings. Despite weighing only around 35 lb, it delivers up to 230 A, allowing you to tackle a wide range of materials — from delicate aluminum to 3/8-inch steel. With its user-friendly Auto-Set™ technology, even less experienced welders can dial in ideal weld parameters quickly. The Quick Select™ drive roll simplifies changing between solid and flux-cored wire, and advanced features like Smooth-Start™ minimize spatter for cleaner starts. Plus, with USB-enabled firmware updates, your welder can grow as your skills do — while a 15-foot MDX-100 MIG gun and dinse connections help you weld longer and with fewer interruptions. The 211 PRO is a reliable, future-proof investment for fabrication, automotive work, and repair-and-maintenance.
Key Features:
-
Dual-Voltage (120/240 V): No tools needed — just swap MVP™ plug and you're ready for either standard household or workshop power.
-
Wide Amperage Range: 30–230 A, so you can weld thin gauge sheet up to 3/8" steel or aluminum.
-
Auto-Set™ Technology: Predefined weld settings make setup fast, accurate, and repeatable.
-
Inverter Technology: Lightweight, portable design (approx. 35 lb), but maintains excellent arc performance and stable welding.
-
Smooth-Start™: Provides a spatter-free arc start, reducing mess and cleanup.
-
Quick Select™ Drive Roll: Three-groove drive roll supports different solid wire sizes and flux-cored wire, making wire changes faster and easier.
-
USB Port for Upgrades: Easily update software, back-up weld settings, or transfer programs via USB.
