WELDING SET

Higher Speed and Greater Penetration

A RECENT addition to the Esab range of semi-automatic welding units is the A9 400 unit. It is based ลด the

A9 200 company's

and A9 275 machines but uses a larger

Esab A9/400 welding set

welding rectifier. Higher welding speeds. greater penetration and grea- ter deposition rates are thus achieved and thicker plates can be welded.

The A9 400, like the smaller units carries all welding elements

weld- ing wire, current and gas in a flexible conduit which gives greater manoeuvrability and less strain the operator.

The unit is suitable for short-arc and spray-arc welding and is supplied
