TIG mode
• The remote will default to the 6-pin MS-style if a
remote control is connected to the 6-pin MS-style
and to the 14-pin MS-style connectors. If a remote
is not connected to the 6-pin MS-style connector
then the remote will default to the 14-pin MS-style
connector if a remote is connected.
• If a remote control is connected to any of the
amphenols the WELD TERMINAL control will
default to REMOTE. If there are not any remote
control devices attached the WELD TERMINAL
control will default to ON.
TIG CONTROL MODuLE: To access this mode use
the Weld Mode Control button to scroll through all of
the welding modes until the lights for the CC-STICK
"SOFT" and CC-STICK "CRISP" are both illuminated.
This mode is intended to supply power to control mod-
ules that independently control welding output.
• The displayed output for this mode will always be
set to 425 amps and cannot be changed. The actu-
al output will be dictated by the current and voltage
draw of the connected module.
• The hot Start Control and Arc Control are not used
in this mode.
• The output is automatically enabled when this
mode is selected and the "ON" display will be lit.
CC-Stick modes
• The remote will default to only the 6-pin amphenol if
a remote is connected to it.
• The WELD TERMINAL control will default to ON
with or without a remote connected.
Types of Remote OuTPuT CONTROL
• The EX350ie (CE) Output Control can be controlled
by either a potentiometer connected between 77 &
75 with the wiper connected to 76 or a 0V to 10V
DC supply connected between 76 & 75. (76 needs
to be positive)
• 14-pin MS-style connector lead 75 is pin G, lead 76
is pin F and lead 77 is pin E.
• 6-pin MS-style connector lead 75 is pin C, lead 76
is pin B and lead 77 is pin A.
Potentiometer Control
• The total resistance should be between 2000 ohms
(2K) and 10,000 ohms (10K)
• The machine output will be at minimum when lead
76 (wiper) is at the end of the potentiometer that is
connected to 75. The machine's output will
increase as the wiper of the potentiometer is moved
to the end that is connected to 77. (Note: In TIG
mode, moving the lead 76 (wiper) to lead 77 would
produce the current that has been set by the
EX350ie (CE) front panel Output Control.)
• Remotes of this type offered by Lincoln Electric are
the K857, K812 and K870.
OPERATION
Voltage Control
• The supply should be an isolated supply. (Not ref-
erenced to earth ground, any auxiliary power from
the EX350ie (CE) or the welding output) The supply
should be capable of supplying at least 20mA.
• 0 volts supplied to 76 will set the EX350ie (CE) to
minimum output for the mode that has been select-
ed while 10 volts supplied to 76 will set the
EX350ie (CE) to the maximum output for the mode.
(Note: In TIG mode, 10 volts supplied to lead 76
would produce the current that has been set by the
EX350ie (CE) front panel Output Control.)
Types of Remote WELD TERMINAL Control
• The EX350ie (CE) Weld Terminals can be con-
trolled from each of the amphenol connectors. The
circuit has a nominal OCV of 15VDC and requires a
dry contact closure (less than 100 ohms) to activate
the output of the EX350ie (CE).
• 14 Pin Amphenols the Weld Terminals are con-
trolled from pins C (lead 2) and pin D (lead 4). Pin
C is positive.
• 6 Pin Amphenol the Weld Terminals are controlled
from pin D (lead 2) and pin E (lead 4). In the 6-pin
amphenol pin D is positive.

AuXILIARY POWER

• 42VAC and 24VAC power is available from the 14-
pin MS-style connector. These supplies are intend-
ed to supply power for auxiliary equipment like wire
feeders.
• 42 VAC supply is rated at 5.5 amps and is protect-
ed by a 10 amp breaker located by the amphenol.
• 24 VAC supply is rated at 5.5 amps and is protect-
ed by a 10 amp breaker located by the amphenol.

LIMITATIONS

• The EX350ie (CE) is not recommended for
processes other than those listed.
• The EX350ie (CE) can only be used with the rec-
ommended equipment and options.

RECOMMENDED PROCESSES

Properly equipped, the EX350ie (CE) supports
GMAW, FCAW, SMAW, GTAW and CAC-A
processes for a variety of materials, including mild
steel, stainless steel, cored wires, and aluminum.
