4-11. Postflow Time Control1 Postflow Time Control
Use control to set length of time
(0–50 seconds) gas flows after
welding stops. It is important to set
enough time to allow gas to flow un-
til after the tungsten and weld
puddle has cooled down.
Application:
Postflow is required to cool tung-
sten and weld, and to prevent con-
tamination of tungsten and weld. In-
crease postflow time if tungsten or
weld are dark in appearance.
