4-11. Postflow Time Control
1 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.
