The welding parameters are described in the following in the order shown in fig.
9.
3.6.2 Gas preflow time
The gas preflow time is set as described in Chapter 3.6.1.
The gas preflow time is the time in which the inert gas valve is opened after the
torch button 1 has been pressed in order to start a welding procedure, before the
arc is ignited. This causes the arc to be lit with an inert gas shielding layer, which
protects the electrode and the workpiece from burning out.
If the welding procedure is restarted during the gas post-flow time, the gas
preflow time is automatically set to 0 seconds by the processor controller. This
speeds up re-ignition, which saves time when tacking, for example.
3.6.3 Ignition energy
The ignition energy is set as described in Chapter 3.6.1.
The ignition energy can be adjusted to a value of between 10 and 100% when
igniting with high frequency or Lift Arc (infinitely variable).
Depending on the selected value for the ignition energy, the processor controller
defines a preselection for the required ignition process. This preselection can
now be adapted to the selected electrode (type, diameter), the gas type and the
respective welding task depending on the polarity by adjusting the ignition
energy.
During welding work with thin materials and small electrode diameters, less
ignition energy should be selected.
In AC welding systems "power ignition" is carried out with an ignition energy
setting of 90% or above, which makes ignition easier in harsh environments.
