Semi-automatic Welder Magnum MIG 278 MMA
Magnum MIG 278 MMA is a powerful three-phase semi-automatic welder, designed as a dependable workhorse for professional use. Supplied from a 400V mains and fitted with a solid four-roll wire feeder, it gives steady, efficient work in repair shops, in agriculture and on light and medium structural projects. It is a sound choice for professionals who value power, reliability and simple operation.
Key features
Strong and stable three-phase 400V supply
High welding current up to 280A at a 60% duty cycle
Professional four-roll wire feeder (4×4) for steady feeding
Flexibility 3-in-1: MIG/MAG welding, MMA and self-shielded FLUX wire
Takes large wire spools (5/15 kg), which raises working output
Solid, hard-wearing build made for heavy use
Technical details
Technology in detail
The heart of the machine is a modern inverter board in IGBT technology, which keeps energy losses low and holds a stable welding arc. The part that sets this model apart in its class is the professional four-roll feed mechanism (4×4). It feeds the wire smoothly and precisely, which is needed when working with long welding torches (4-5m) and when welding with aluminium wires. Polarity can be reversed, so FLUX welding (FCAW) is possible without an external gas cylinder, which adds a lot to the mobility of the set.
Recommended applications
- Professional metalwork and repair shops
- Steel structures of light and medium load
- Production and assembly work
- Agriculture and plant maintenance
- Welding carbon and stainless steels and aluminium (after changing the setup)
Control panel
The control panel of the Magnum MIG 278 MMA welder was laid out for simplicity and reliability. It has two clear digital displays showing the welding voltage and current. Parameters are set with proven manual knobs, which allows precise and quick setting of the arc voltage, the wire feed speed and the inductance. Experienced welders value this layout for how intuitive it is and how well it stands up to hard workshop conditions.
