7 Flow Adjust
Typical flow rate is 20 cfh (cubic feet
per hour) (9.4 L/min).
After activating remote control, 0.2

Preflow Application:
Preflow is used to purge the imme-
diate weld area of atmosphere.
Preflow also aids in consistent arc
starting. Preflow is preset and is not
adjustable.
Post Flow 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 (see
Section 3-8).
