Sorry for mi BAD German, so I will explain this on English. Agl is excellent for thick Aluminum and their alloys. Looking to physics od Welding , IT is known that for thick Aluminum and their alloys, we use Helium and not Argon, regarding higher heat input of Helium. In the other hand, Helium shows erratic coverage of weld pool, so German company established gas composition of 90% Helium and 10…% Argon, for arc stabilysing purposes. Advantages occurred mainly in cheaper GTAW machine ( DC, and not AC), and enorm penetration,when compared to AC with pure Argon. Disadvantages occurs when welding should performed on thin aluminum plates or tubes, and enorm costs of shielding gas (Helium). in meantime I recommend one of the processes that have “ near MIG “ productivity, and GTAW quality, and that is TIP - TIG welding process, with hot wire feeding. With that process, all materials that can be blended as a wire in welding spool can be welded, including Aluminum and their alloys.
