The Warrior 330 Three-Phase MIG Welder is a powerful 300 Amp inverter MIG welder with a 415V three-phase input, ideal for general fabrication and digger bucket repair. If you’re looking for a 300A MIG welder but with extra oomph, the Warrior 330 MIG Welder is the machine for you.

The Warrior 330 Three-Phase MIG Welder weighs only 32kg, including a 15kg wire spool with cover. This welding machine’s highly portable and efficient design allows it to run off a generator, including our Bison Whisper Three-Phase 10kVA Diesel Generator, a Mosa 300 and a Genset 300.

Soft start prevents wire tangling and uses less than 30% electricity than a conventional transformer-based machine, whilst its powerful four roller wire-feed is superb for aluminium welding. Our optional Warrior Aluminium MIG Welding Kit enables you to modify your Warrior 330 MIG Welder to start welding aluminium immediately.

Our 300A MIG welder provides stepless adjustable welding voltage and wire speed with excellent welding characteristics, including variable burnback and spatter control, and has the capacity to be run as a water-cooled machine; increasing the machine’s efficiency, operating time and amperage.

Unlike other companies, we can provide bespoke built-in Goblin Fume Extraction for the Warrior 330 Three-Phase MIG Welder; an independent twin fan ventilation design with comprehensive protection (anti-dust, anti-moisture, anti-corrosion).

    A dream to weld with


    I own a small Marine Engineering Company. I purchased the awesome Warrior MIG from Phil. Not only is this probably the most powerful portable inverter MIG in its class but it is just a dream to weld with. The very clever arc sensing wire feed eliminates burnback and prolongs tip life. When pumping in the amps on heavy plate your hand will overheat a long time before the machine does! Phil is dedicated to first class after sales & service and is always just a call away for welding tips & hints should you wish to make the very best of your skills & machine. Phil was so confident in the quality of his machine he allowed me to trial the warrior machine for an indefinite period and to be honest it has exceeded even my expectations. In the unlikely event I had a problem with my machine, I have every confidence Phil would sort out it out with the greatest of efficiency.
