ESAB A6 S is an automatic welding machine intended for fillet and butt welding, compatible with column and boom units, trolleys, or other equipment. It suits applications such as internal welding in pipes or pressure vessels, strip cladding, or air-arc gouging.

The A6 S supports both single-wire and double-wire (twin arc) welding, featuring a permissible load of up to 1500A DC/AC or 600A DC, and a maximum wire feed speed of 4 m/min for submerged arc welding or 17 m/min for MIG/MAG welding. Its compact design, with an adjustable angular slide for precise positioning, enables welding in confined or hard-to-reach areas.
