2 INTRODUCTION
The RobustFeed AVS (Arc Voltage Sensing) is a portable wire feeder. The unit is powered entirely on
the arc voltage from a constant current (CC) or constant voltage (CV) welding power source. It
operates with reversed polarity (Direct Current Electrode Positive - DCEP) or straight polarity (Direct
Current Electrode Negative - DCEN).
The wire feed unit comes in different versions (see the "ORDERING NUMBERS" appendix).
The wire feed units are sealed and contain four-wheel drive wire feed mechanisms as well as control
electronics.
They can be used together with wire on ESAB's Marathon Pac™ or on wire bobbin (standard Ø 200
mm and Ø 300 mm).
The wire feed unit can be placed on a trolley, suspended above the workplace or on the floor (standing
up or laying down and with or without a wheel set).
ESAB accessories for the product can be found in the "ACCESSORIES" chapter of this manual.
