With the introduction of new Murex Tradestig portable welding units, welding craftsman will have the optimum solution for a wide range of TIG AC/DC welding applications within repair and maintenance functions, general light fabrication and civil construction, process industry, shipbuilding and offshore, transport and mobile machinery markets.

he Tradestig AC 220 and AC 220a machines are compact and impact resistant with a polymer and aluminium casing.  They are light and easy to carry, and as they are built in accordance with IP23, they can be used both indoors and outdoors.  The durable design and the superior welding performance give you a machine that you can rely on day after day.

A key feature is the Power Factor Correction (PFC) which makes it possible to use the full range of the machine on a 16 A fuse. The PFC also protects the machine against fluctuating mains voltage and makes it safer to use with a generator.

In both AC and DC mode these TIG welding machines will give an excellent arc strike and consistent, stable arc. All types of material and thickness up to 5 mm can be welded with the highest quality. Two easy to use control panels are available with the necessary functions for TIG DC, AC/DC and MMA welding.

One of the most important tasks of an AC TIG Welding machine is to provide a stable arc. The QWave™ function optimises the AC wave form to give a smooth arc and at the same time the lowest possible noise without compromising the weld result.  This machine also has True AC rating where the actual welding current is always equal to the set current.
