Digital gas management
Gas quantities can be programmed individually. Various possibilities of adjusting the gas pre purge time and gas post
purge time:
X
The transmission of the weld head is to be kept permanently free of oxygen during idling. This allows the gas pre
purge time as well as the process time to be reduced.
8.3.5
Adjusting gas times
Auto programming generates gas pre and post purge times of 30 seconds for cassette weld heads. The adjustment of
the gas times (gas pre purge time and gas post purge time) may be necessary to optimize the results of the welding
process.
The space to be filled with gas also depends on the weld head size and pipe diameter. It may therefore be necessary to
shorten the gas pre purge time for smaller weld heads. If the seam (with closed weld heads) is bare and nearly free of
annealing colors right from the beginning, the gas pre purge time is correct. For special materials (e.g. titanium), it may
be necessary to lengthen the gas times. The gas post purge time must at least be long enough that the material no longer
reacts to oxygen in the air when the closed weld heads are opened. This also depends on the energy introduced during
welding.
Cassette weld heads:
Due to electrode oxidation, do not use a gas post purge time of less than 10 seconds.
LP weld tongs:
Do not change the gas times specified by auto programming.
