Dirt. Drops. Mud. Rain. Game on. You are a welder, and you are not afraid to get your hands dirty. You work in some of the toughest conditions, and you need equipment you can take anywhere. That is why we created Robust Feed – our most durable, ergonomic, and high-performing wire feeder yet.

The Robust Feed PRO – OS, with its ergonomic, robust and enclosed design, is the ideal partner whenever portability and durability are key. Equipped with a new precision wire drive system with enough power to handle up to 2.0 mm solid wire and 2.4 mm cored wire, it is the perfect partner to various ESAB equipment, including the Warrior 400 and 500.


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.
