B-8 OPERATION B-8
CV-INNERSHIELD
This weld mode is a constant voltage (CV) mode fea-
turing continuous control from 10 to 45 volts. It is
intended for the FCAW-SS welding process.
Hot Start – Toggle to “ON” position to provide more
energy during the start of a weld.
Arc Control – The Arc Control regulates pinch effect.
At the minimum setting (-10), minimizes pinch and
results in a soft arc. At the maximum setting (+10),
maximizes pinch effect and results in a crisp arc.
Weld Terminals On/Remote
• When set to the “ON” position, the weld terminals
are at OCV (open circuit voltage) and ready to weld.
This selection is used for across the arc wire feed-
ers.
• When set to the “REMOTE” position, output is
enabled through a remote trigger.
Amperage Display Meter – This display will display
three dashed lines when the machine is in the idle
state. This indicates that amperage is not settable in
this weld mode. While output is enabled, the actual
welding 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" peri-
od.
Voltage Display Meter – This display will display the
pre-set welding voltage 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 voltage value for 5 seconds. Output adjust-
ment while in the "hold" period results in the "prior to
operation" characteristics. The displays blink indicat-
ing 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. Set this switch to “REMOTE”
when an external potentiometer/control is connected.
Output Control Dial
• When the Local/Remote is set to Local, this dial sets
the welding voltage.
• When the Local/Remote is set to Remote, this dial is
disabled
FLEXTEC™ 450 CE
The remote potentiometer controls the amperage from minimum
to this pre-set maximum.
CV-GAS
This weld mode is a constant voltage (CV) mode featuring con-
tinuous control from 10 to 45 volts.
It is intended for the GMAW, FCAW-GS, MCAW welding
processes.
Hot Start – Toggle to “ON” position to provide more energy
during the start of a weld.
Arc Control – The Arc Control regulates pinch effect
(Inductance). At the minimum setting (-10), minimizes pinch and
results in a soft arc. Low pinch settings are preferable for weld-
ing with gas mixes containing mostly inert gases. At the maxi-
mum setting (+10), maximizes pinch effect and results in a crisp
arc. High pinch settings are preferable for welding FCAW-GS
and GMAW with CO
2 .
Weld Terminals On/Remote
• When set to the “ON” position, the weld terminals are at OCV
(open circuit voltage) and ready to weld. This selection is
used for across the arc wire feeders.
• When set to the “REMOTE” position, output is enabled
through a remote trigger.
Amperage Display Meter – This display will display three
dashed lines when the machine is in the idle state. This indi-
cates that amperage is not settable in this weld mode. While
output is enabled, the actual welding 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 indi-
cating that the machine is in the "hold" period.
Voltage Display Meter – This display will display the pre-set
welding voltage when the machine is in the idle state. While out-
put is enabled, the actual weld amperage 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.
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.
Output Control Dial
• When the Local/Remote is set to Local, this dial sets the
welding voltage.
• When the Local/Remote is set to Remote, this dial is disabled.
