7.3 Overview of welding parameters and processes
7.3.1 Overview of welding parameters
7.3.2 Overview of welding procedures
The possible combinations of welding procedures are listed in the following tables and can be selected by
the connected robot via the interface. If an impermissible combination is selected, this is indicated in the
right/left blinking digital display <->.
The welding procedures produce high-quality welding results only with the specified shielding gases and
shielding gas combinations. Changes to the shielding gases and shielding gas combinations always affect
the welding results.
If shielding gas mixtures other than the following are used, the automatic voltage adjustment will not reach
the correct value.
