Slow Wire Feed (Fig. 9-3) –
The welding unit has a feed-on-demand system to
prevent wire waste. Initially the wire is slowly fed through the torch, regardless
of the set speed. Once an arc is struck, the unit feeds the wire at the user’s
selected speed.
Burnback Setting (Fig. 9-4)
– Burnback is a feature that continues to supply
power to the welding wire after the torch trigger is release, but stops the
welding wire from feeding. This provides time for the welder to remove the
welding wire from the weld pool before it solidifies. The setting is preset by
the factory.
Gas Post-Flow (Fig. 9-5)
– Choose the length of time the gas flows after the arc
is extinguished to prevent weld contamination.
Load and Save (Fig. 9-6 and 9-7)
– The MIG settings may be saved into the
memory and then reloaded for future welding tasks.
TIG –
The current parameter is adjustable.
There is no foot pedal option with this welder.
STICK (ARC) –
The current, arc force and
hot start parameters are adjustable. VRD is
ON or OFF.
ARC Force (Fig. 11-1) –
Welding in difficult
areas or angles may require a longer arc length,
creating a voltage drop. The ARC Force
increases the amperage to compensate for the
lost power and maintain the heat of the weld.
Hot Start (Fig. 11-2) –
The current increases
temporarily during arc ignition to make sure a
reliable arc is quickly established.
Voltage Reduction Device (VRD) (Fig. 11-3) –
Select to turn VRD ON or
OFF. VRD reduces the voltage at the welding torch or electrode when there is
no load.
WARNING! VRD does not shut the voltage off. The welding torch or electrode
is still live and can inflict an electrical or burn injury if touched.
