Fronius 3400 Used Mig Welder
Product overview
About this machine.
Fronius is a global leader in advanced welding technology, known for delivering precision, reliability, and innovation in every weld. Designed for professional fabricators and industrial applications, Fronius welding machines feature cutting-edge inverter technology, exceptional arc stability, and user-friendly digital controls. From MIG/MAG, TIG, and Stick welding to automated and robotic solutions, Fronius systems provide consistent performance, energy efficiency, and superior weld quality across a wide range of materials and thicknesses.
The Fronius VarioSynergic 3400 is an industrial grade MIG/MAG welding power source engineered for serious structural steel, machinery, and container fabrication work. With a welding current range spanning approximately 10 - 340 A, it gives you the capacity to handle moderate to heavy fabrication jobs with confidence. It features synergic control technology: simply set the material thickness and filler wire type, and the machine automatically adjusts voltage, current and deposition behavior, greatly simplifying setup and boosting consistency. A strong build underscores its suitability for industrial use: it includes a 4-roller wire feed drive for smooth wire impressions, automatic cooling cut-out, and protection rating of IP23 for tougher environments.
Key performance highlights:
- 3 phase supply
- Open-circuit voltage around 45 V.
- Working voltage roughly 14.5 - 31.0 V.
- Generator compatible design, making it suitable for onsite or remote power scenarios.
Please note:
- We have not internally tested this machine as we do not have the capacity. We welcome you bringing your own gas bottle and running it through its paces before purchasing.
- We believe it is in good working order.
