• Prior to STICK or TIG operation (current flow), the
meter displays preset current value.
• Prior to CV operation, the meter displays four dash-
es indicating non-presettable AMPS.
• During welding, this meter displays actual average
amps.
• After welding, the meter holds the actual current
value for 5 seconds. The displays blink indicating
that the machine is in the "hold" period.
•Output adjustment while in the "hold" period results
in the "prior to operation" characteristics

• This switch determines the trigger location.
• When set to the V$#W position, the weld terminals
are at OCV (open circuit voltage) and ready to weld.
• When set to the V'"$)W position, output is
enabled through a remote trigger.
?>DB?<!?31<'5=?D5)?77<5(G9D38
• Set the switch to V!?31<W to control output at the
machine by the Output Control dial.
• Set the switch to V'"$)W to control output via a
remote device (K857 hand amptrol or K870 foot
amptrol) connected to the @9> remote connector
or a wire feeder connected to the @9> connector.

• This status light indicates when the power source
has been driven into thermal overload. If the output
terminals were $#, the output will be turned back
on once the unit cools down to an acceptable tem-
perature level. If the unit was operating in the
'"$) mode, the trigger will need to be
opened before or after the thermal has cleared and
closed after the machine has cooled down to an
acceptable temperature to establish output.

This weld mode is a constant current (CC) mode fea-
turing continuous control from 15 – 500 amps. It is
intended for the SMAW stick welding processes and
arc gouging.
?D(D1BD The Hot Start control regulates the starting
current at arc initiation. Hot Start can be set to V$66W
and no additional current is added at arc start. When
set to the V$>W position, additional current (relative to
the preset current) at arc initiation.

B3?>DB?< The Arc Control regulates the Arc Force
to adjust the short circuit current. The minimum setting
(-10) will produce a "soft" arc and will produce minimal
spatter. The maximum setting (+10) will produce a
"crisp" arc and will minimize electrode sticking.
,5<4)5B=9>1<C$>'5=?D5U Set to V$>W so the
machine is in the ready to weld state.
+?<D175 9C@<1I"5D5BU This display will display
three dashed lines when the machine is in the idle
state. This indicates that voltage is not settable in this
weld mode. While output is enabled, the actual weld-
ing voltage is displayed. After welding, the meter
holds the actual voltage value for 5 seconds. Output
adjustment while in the "hold" period results in the
"prior to operation" characteristics. The displays blink
indicating that the machine is in the "hold" period.
=@5B1759C@<1I"5D5BU This display will display
the pre-set welding current when the machine is in the
idle state. While output is enabled, the actual weld
amperage is displayed. After welding, the meter holds
the actual amperage value for 5 seconds. Output
adjustment while in the "hold" period results in the
"prior to operation" characteristics. The displays blink
indicating that the machine is in the "Hold" period.
$ED@ED?>DB?<!?31<'5=?D5U When the control is
set to local (no remote potentiometer/control plugged
into the @9> or @9> connectors), the output is con-
trolled through the Output Control Dial on the front of
the Flextec™ 450. Set this switch to V'"$)W
when an external potentiometer/control is connected.
• When a remote potentiometer is connected, the out-
put control on the Flextec™ 450 and the remote act
as a master/slave configuration. Use the control
dial on the Flextec™ 450 to pre-set the maximum
welding current. The remote will control output from
minimum to the pre-set maximum.
$ED@ED?>DB?<91<
• When the Local/Remote is set to !?31<, this dial
sets the welding amperage.
• When the Local/Remote is set to '5=?D5, this dial
sets the maximum welding amperage. The remote
potentiometer than controls the amperage from min-
imum to this pre-set maximum.
