B-7 OPERATION B-7
• When the Local/Remote is set to Remote, this dial
sets the maximum welding amperage. The remote
potentiometer than controls the amperage from min-
imum to this pre-set maximum.
GTAW
This weld mode is a constant current (CC) mode featuring con-
tinuous control from 10 – 500 amps. It is intended for the GTAW
TIG welding processes.
Hot Start - The Hot Start control regulates the starting current
at arc initiation. Hot Start can be set to “Off” and no additional
current is added at arc start. When set to the “On” position,
additional current (relative to the preset current) at arc initiation.
Arc Control – This control is not used in the GTAW mode.
Weld Terminals On/Remote
• When set to the “ON” position, the weld terminals are at OCV
(open circuit voltage) and ready to weld.
• When set to the “REMOTE” position, output is enabled
through a remote trigger.
Voltage Display Meter – 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 welding 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.
Amperage Display Meter – 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 sec-
onds. 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.
Output Control Local/Remote – When the control is set to
local (no remote potentiometer/control plugged into the 6-pin or
14-pin connectors), the output is controlled through the Output
Control Dial on the front of the FLEXTEC™ 450 CE. Set this
switch to “REMOTE” when an external potentiometer/control is
connected.
• When a remote potentiometer is connected, the output control
on the FLEXTEC™ 450 CE and the remote act as a
master/slave configuration. Use the control dial on the FLEX-
TEC™ 450 CE to pre-set the maximum welding current. The
remote will control output from minimum to the pre-set maxi-
mum.
Output Control Dial
• When the Local/Remote is set to Local, this dial sets the
welding amperage.
• When the Local/Remote is set to Remote, this dial sets the
maximum welding amperage.

BASIC MODES OF OPERATION
MMAW
This weld mode is a constant current (CC) mode fea-
turing continuous control from 15 – 500 amps. It is
intended for the MMAW stick welding processes and
arc gouging.
Hot Start - The Hot Start control regulates the starting
current at arc initiation. Hot Start can be set to “Off”
and no additional current is added at arc start. When
set to the “On” position, additional current (relative to
the preset current) at arc initiation.
Arc Control - 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.
Weld Terminals On/Remote – Set to “On” so the
machine is in the ready to weld state.
Voltage Display Meter – 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.
Amperage Display Meter – 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.
Output Control Local/Remote – When the control is
set to local (no remote potentiometer/control plugged
into the 6-pin or 14-pin connectors), the output is con-
trolled through the Output Control Dial on the front of
the FLEXTEC™ 450 CE. Set this switch to
“REMOTE” when an external potentiometer/control is
connected.
• When a remote potentiometer is connected, the out-
put control on the FLEXTEC™ 450 CE and the
remote act as a master/slave configuration. Use the
control dial on the FLEXTEC™ 450 CE to pre-set
the maximum welding current. The remote will con-
trol output from minimum to the pre-set maximum.
Output Control Dial
• When the Local/Remote is set to Local, this dial
sets the welding amperage.
