WARNING! Work that is carried out incorrectly can cause serious injury and dam-
age. The welding sequence must only be programmed by trained specialist per-
sonnel. Observe the safety regulations in the operating instructions, paying
particular attention to the section entitled "Safety inspection".
NOTE! When welding a number of short weld seams one after the other, do not
switch off the crossjet flow and external extraction until the end of the entire se-
quence. This will prevent welding smoke from making the protective glass dirty.
Set the "extraction on" signal
Set the "Crossjet on" signal
Select the mode
e.g. mode "3" (internal parameter selection for adjustment purposes):
set mode bit "0" to "1"
set mode bit "1" to "1"
set mode bit "2" to "0"
If "Job" mode is selected, see the operating instructions for the MIG/MAG power
source for more detailed information about this mode.
If preheating is not required, continue from "LaserHybrid welding start position".
Set the "gas test" signal
Set the "laser on" signal
The preheating temperature comes from the following factors:
travel speed,
laser power,
distance to the surface of the workpiece
Reset the "laser on" signal
Reset the "gas test" signal
Set the "arc on" signal
Wait for the current flow signal ("arc on")
