Carbon dioxide for arc welding

Supply of welding posts with carbon dioxide can be carried out the next ways:
directly from autonomous station on production of carbonic acid;
from a stationary vessel store - at the considerable volumes of consumption of carbon dioxide and absence at the enterprise of own autonomous station;
from transport carbon dioxide capacity - at the smaller volumes of consumption of carbon dioxide;
from cylinders - at the insignificant volumes of use of carbon dioxide or impossibility of laying of pipelines to a welding post.
