3-8. Postflow Time Control
1 Postflow Time Control
Use control to set the length of time
in seconds gas (and coolant if appli-
cable) flows after welding stops.

3-9. High Frequency Controls
USING HIGH FREQUENCY WITH THE SHIELDED METAL ARC WELDING (SMAW) PROCESS can result in
serious personal injury.
•
Place the High Frequency switch in the Off position before using the Shielded Metal Arc Welding (SMAW) Process.
WARNING
1 High Frequency Switch
Off – No HF. Use Off for SMAW
welding.
Start – provides HF for arc starting
only.
Continuous – provides HF continu-
ously throughout the weld.
2 High Frequency Intensity
Control (see Section 2-9)
Use control to change amount of
HF energy used to start and main-
tain the arc. Set as low as practical
to prevent interfering with electronic
equipment. Numbers around the
control are for reference only.

3-10. Crater Fill Switch
1 Crater Fill Switch
In – provides crater time;
Out – provides no crater time.
Place switch in the Out position for
SMAW.
Use crater to taper weld output from
setting of the Amperage Adjust-
ment control to the minimum of the
unit.
When using the crater time circuit,
set Postflow Time Control (see
Section 3-8) for at least 8 to 10
seconds.
