Wedge Cleaning; Changing The Wedge Holder / Changing The Welding Width - Leister SEAMTEK W-AT Series Manual

8.2 Wedge Cleaning

When the wedge is positioned properly and the welding parameters are set correctly, very little slag is formed. It is
mainly limited to the front part of the wedge (22). If an excessive amount of slag is formed, readjust the wedge and
reduce the energy value.
Clean the wedge at regular intervals to remove slag and impurities. Use a plastic scraper to remove the slag. If the
welding performance deteriorates or mechanical damage occurs, replace the wedge (Chapter 8.5).

8.3 Changing the Wedge Holder / Changing the Welding Width

The wedge holder must be replaced in the event of damage or if the welding width needs to be changed.
Thanks to the quick-change system, the holder can be replaced quickly and easily. Turn screws 2A and 2B a quar-
ter-turn counterclockwise while holding on to the wedge. The wedge holder can then simply be lowered and removed.
