ESAB has different flux equipment/systems to combine with automatic submerged-arc welding equipment. The OPC<br />

<br />

and A6 equipment, both stationary and travelling. The FFRS-systems (flux feed and recovery) are designed for<br />

continuous, high-capacity welding operations. They are ideal for long runs and mass production.<br />

Handling<br />

<br />

<br />

ESAB has a comprehensive range of positioners for automatic welding. These<br />

very versatile handling tools enable welding to be carried out in the optimum<br />

positions to enhance productivity and quality. They are easily integrated with<br />

A2/A6 automatic welding equipment.<br />

<br />

mechanical adjustment for circular workpieces and self-aligning roller beds<br />

which automatically adapt to the workpiece diameter. These roller beds are<br />

designed to operate in combination with A2/A6 automatic welding equipment<br />

and ESAB column and booms.<br />
