At that time, there were no uniforms and the hockey players wore gym shorts, soccer socks, football jerseys, and skates known as Friesen, which used shoes made of wood with a metal bar as a runner, which were laced with leather straps on the feet.

In the 1933–34 season, EC KAC won its first league title and thus stopped the almost uninterrupted dominance of the Vienna Ice Skating Association.

The Second World War interrupted play abruptly and post-war it took a long time to get the league back functioning properly.

With games still played outdoors and susceptible to inclement weather, on 22 November 1959, the Stadthalle Klagenfurt complex opened, which after several modifications is still in use today as the home rink of EC KAC.

At the turn of the 1960s, with the influx of influential players such as Dieter Kalt Snr and Sepp Puschnig, KAC sowed the seeds in dominating the Austrian championship from 1964 to 1980, in which the title went fifteen times to Klagenfurt.
