The Warrior 250 Single-Phase MIG Welder and Bison Mark II 10kVA Diesel Generator is the ideal set for on-site welding; portable, powerful and efficient.

The Warrior 250 Single-Phase MIG Welder is a portable 200A/240V inverter MIG welder. Weighing only 32kg, including a 15kg wire spool with cover, this welding machine is highly portable making it ideal for on-site fabrication. With soft start and a powerful four roller wire-feed, it is ideal for aluminium welding. Straightforward to use and high-quality, this MIG welding machine is constructed using IGBTs and plug in circuit boards for reliability and easy maintenance. The Warrior 250 Single-Phase MIG Welder’s highly efficient design allows it to run off our Bison Mark II 10kVA Diesel Generator; ideal for transportation and use away from the workshop.

The Bison Mark II Generator is a portable, air-cooled, single-cylinder, 10kVA diesel generator, producing 110V and 240V single phase output. Complete with remote start/stop key fob, this open-framed generator has a 680cc electric-start diesel engine which produces 15hp. It is fitted with a low oil pressure alert system that shuts down the engine automatically. The Bison Mark II Diesel Generator has a modified AVR (Automatic Voltage Regulator) that reacts to an inductive load, delivering a non-fluctuating current to perfectly run the Warrior 250 Single-Phase MIG Welder.

    Salute to Phil


    Everything is superb – I have been welding with it for about 2 hours now, configured and marked up all my amp settings and it runs great and super smooth, especially at 220 amps where, with a steady hand, it only deviates +/-2 amps! Salute to Phil for doing a remarkable job on setting these up! For many years I have pondered on having a MIG plant running off a genny instead of using genset stick, especially for speed and troublesome large gaps to fill. Can’t wait to get out onsite and try it.

    That’s the 250 powered by the new 10kva generator. Near Bradford on Avon and it’s an adaptor plate for the front of a telehandler. Welding 1.2mm wire at 225 amps.

    Excellent product at an affordable price


    I would just like to say thank you for the explanations and overall experience. When I returned home I couldn’t wait to get stuck in. This welder is without doubt the finest machine I’ve ever used, especially on thin sheet steel, I would never have believed it if I hadn’t seen it with my own eyes, that a MIG of all things could weld two thin pieces of sheet on its ends. Thanks Phil for your effort in maintaining the notion that we in this country can still produce the best welding machines. Your dedication and commitment to making such an excellent product at an affordable price leaves me speechless.
