setting range
factory setting
The value set for G-H only applies if the maximum welding current really has been set.
The actual value is derived from the instantaneous welding amperage. With a medium
welding amperage, for example, the actual value will be one-half of the value set for G-
H.
Important! The values for the set-up parameters G-L and G-H are added together. For
example, if both parameters are on maximum (40 s), the gas post-flow will last:

-
If Aut is selected, the gas post-flow time G-H is calculated automatically. This takes the
selected process (AC or DC welding) into account.

Gas Purger - Purging of shielding gas
Unit
Setting range
Factory setting
Purging of the shielding gas begins as soon as GPU is allocated a value.
For safety reasons, purging of the shielding gas cannot be restarted until a new GPU
value is entered.
Important! Purging with shielding gas is necessary if condensation forms when the
device is left unused in a cold environment for a prolonged period. Long hosepacks are
most affected.
