The ESAB Warrior 400i CC/CV brings the outstanding arc performance and energy savings you expect from an inverter. Along with increased energy efficiency and more power from a lighter, smaller, and more portable unit, Warrior provides the simple functionality welders want at a competitive price.

Perfect for long runs across a variety of applications and delivers 400 amps @ 60% Duty Cycle. Warrior has been designed to be durable and rugged, with an IP23 rating for outdoor and indoor use in the rough environment.
With an easy-to-use, clear and intuitive user interface for everyone to get started quickly, including glove-friendly knobs make adjustments quick and easy.


Robust Feed Pro – OS has three comfortable handles (all are crane certified) and two additional lifting points for best-in-class portability and maneuverability, making it easy to lift and carry through confined spaces and around obstacles.

Rounded edges and special high durability wear surfaces let you drag it anywhere without catching on other objects. The optional flat and vertical wheel kits and trolley integration allow for even greater mobility. The new design can handle power source cables up to 90 metres long, so you will always get to where you need to weld – in the shop or the field.


The new precisely crafted aluminium drive stand feeds solid wire up to 2.0mm and cored up to 2.4mm at speeds of 0.8–25.0m/min. When changing the spool, you can feed the new wire without opening the drive stand. When it comes to power, Robust Feed Pro – OS easily handles 550A at 50% duty cycle, 500A at 60% duty cycle, and 400 A at 100%, enabling productivity that few other portable feeders can.
