3-8. Postflow Time Control

3-9. High Frequency Controls

WARNING
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.

1 Postflow Time Control
Use control to set the length of time
in seconds gas (and coolant if appli-
cable) flows after welding stops.
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.
S-000 485
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.
