Miller MigMatic 320i
£2,098.00
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.
