Setting the gas preflow time (gas test)
An often overlooked source of error is that there is ambient air and moisture in the inert
gas line and inert
gas shroud. It is therefore crucial to maintain a sufficiently long gas
preflow time to expel the ambient air and moisture before each welding process.
If you do not have specified values for the gas preflow time, please refer to the tables in
chapter
“11.1.1 Support tables for device settings from page 62. These may be used as
an aid for a basic setting.
The "Gas test" mode can be used to check that the inert
gas flows through the inert
gas
shroud of the gun. As soon as the release button on the gun is pressed, inert
gas flows
out of the inert
gas shroud of the gun for the time set in seconds. This means the gas
lines can also be flushed with inert
gas before starting work.
During initial start-up or longer periods of non-use, the supply lines of the
inert gas supply must be flushed.
This ensures that the weld pool is reliably covered with inert gas.
Setting the gas preflow time
Step 1:
Connect the device as described in chapter
welding device and the stud welding guns
Step 2:
Use the ↑↓ arrow keys to select the
position for the gas preflow time
setting.
The LED lights up if the selection is
correct.
Step 3:
Use the +/- keys to set the required
value (1-5 s) for the gas preflow time
on the display.
The gas preflow time has been set.
