6-4. Setting Preflow Time
1 Encoder Control
Turn encoder to select from 0 to
25 seconds of preflow. The value
selected is displayed on the am-
meter.
Application: Preflow is used to
purge the immediate weld area
of atmosphere. Preflow also aids
in consistent arc starting.

6-5. Stick Open-Circuit Voltage (OCV) Selection
1 Encoder Control
2 Meter Display
Turn Encoder to change between low OCV
and normal OCV. Active selection is dis-
played on the meters.
When Stick low OCV is selected, open-cir-
cuit voltage is between 9 and 14 volts.
When Stick normal OCV is selected, open-
circuit voltage is approximately 72 volts.
Application: For most Stick applications
use low open-circuit voltage. Use normal
open-circuit voltage for hard to start Stick
electrodes, or if required for your particular
application.

6-6. Stick Stuck Check Selection
1 Encoder Control
2 Ammeter Parameters Select Display
Turn Encoder to change between Stick
Stuck Check [ON and [OFF] meter display.
When Stick Stuck Check is on and the
welding electrode (rod) is stuck, output is
turned off.
Application: For most Stick applications,
use Stick Stuck Check off. With Stick
Stuck Check on and the welding electrode
(rod) stuck, output is turned off in an at-
tempt to save the rod for reuse. This allows
the operator time to un-stick the rod, or dis-
connect the rod holder from the rod without
arc occurring. Turn Stick Stuck Check on
when this function is desired.
.
Some applications may require Stick
Stuck Check to be turned off. For ex-
ample: Large stick electrodes operat-
ing at high amperages would require
Stick Stuck Check to be turned off.
