The Miller MigMatic 320i is a high-performance, workshop-oriented MIG/MAG (GMAW) welding system, designed for professional fabrication, repair and maintenance environments. It delivers synergic wire feed control, a heavy-duty 4-roll drive mechanism and a user-friendly graphical interface — making it ideal for both solid and flux-cored wires (FCAW) in a 400 V three-phase input configuration.

The MigMatic is best suited for:

  • General fabrication and metalwork of medium gauge to thicker materials
  • Automotive repair/body-shop applications
  • Training schools or vocational environments
  • Agricultural equipment, repair and maintenance workshops

Description

Key Features:

  • Synergic MIG/MAG mode: The machine offers preset synergic lines for the most common wire/gas combinations, allowing the operator to set material type, wire diameter and thickness and let the system handle the rest.
  • Heavy-duty 4-roll wire drive: Ensures consistent, precise wire feeding even under demanding usage.
  • Trigger-program switching: Up to 4 pre-set programs can be recalled from the torch trigger (using any standard MIG torch) to boost productivity when working on complex parts.
  • Energy-efficient cooling (Fan-On-Demand™): The machine’s cooling fan operates only when required, reducing noise and contaminant ingress — helpful for cleaner workshop environments.
  • Robust construction: Designed and tested by Miller for heavy-duty workshop use in demanding conditions; built to last.
  • Ease of use & versatility: Large intuitive LCD panel for quick and precise setting of advanced weld parameters. Compatible with Push/Pull torches. Integrated wheels and shelf for a single gas cylinder.
