6.7.5 Gas preflow
The gas pre-flow time is set automatically to the optimum value for the type of material and gas
selected.
6.7.6 Ignition Management
The arc striking process is monitored and optimised to suit the prevailing conditions. This leads to
consistent, reproducible arc striking characteristics under the widest variety of applications.
6.7.7 Forced Shut-down
The forced shut-down function helps to prevent accidents.
Whenever welding is interrupted for more than 3 seconds, the wire-feed, the welding voltage and
the gas are switched off.
6.7.8 Short-circuit monitoring
This function also helps to prevent accidents (both for the user and the machine).
If a short-circuit between the welding wire electrode and the workpiece or anything at the same
electrical potential as the workpiece occurs when welding or using the welding machine the gas, wire-
feed and welding voltage are switched off in fractions of a second. The short-circuit is also displayed
as an error message.
(see 6.6.5.1+6.6.5.2).
