Allowing clean and quiet, virtually smoke-free welding with 100% Argon. The preflow is a purge feature to insure there is airflow at the tip to become a charged plasma stream and benefit for blowing clean cuts. Postflow is primarily for cooling.The longer the cut at high amp on thick metal, the more post flow need to dissipate the heat. Recommend air pressure: 50-60 PSI.
