Remote Control Of The Output Control And Weld Terminals - Red-D-Arc EX350ie Operator's Manual

b-3
• 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.
TIG GTAW: The TIG mode features continuous control
from 5 to 425 amps. The TIG mode can be run in either
the TIG touch start or high frequency assisted start
mode.
• The hot Start control selects the starting mode
desired. A setting of less than 5, the TIG lift start mode
is selected. The OCV is controlled below 10v and the
short circuit "TIG touch" current is maintained at 25
amps independent of the preset current. When the
tungsten is lifted, an arc is initiated and the output is
regulated at the preset value. hot start settings
between 0 and 5 regulate the arc initiation current. A
setting of 5 results in the most positive arc initiation. A
setting of 0 reduces hot start.
• hot Start settings between 5 and 10, select high fre-
quency assisted starting TIG mode. In this range, the
OCV of the machine is controlled between 50 and 70
volts. If using the Lincoln K930-1 TIG Module, set the
hot start to 10 for maximum OCV.
• The Arc Control is not used in the TIG mode.
TIG SOLENOID OPTION
The Solenoid only operates when the EX350ie (CE) is in
the TIG mode. If the Weld Terminals are in "Remote"
then the solenoid will open when the arc start switch is
closed. The solenoid will close after the arc switch has
been opened and the post flow time expired.
If the Weld Terminals are turned "ON", then the solenoid
will open when the electrode is touch to the work. The
electrode needs to remain in contact with the work to
allow for gas coverage before attempting to start the arc.
The solenoid will close after the arc has been broken and
the post flow time expired.
CV-WIRE: The CV-WIRE mode features continuous
control from 10 to 45 volts. The mode was intended for
most GMAW, FCAW, and MCAW applications.
• The hot Start control is not used in the CV-WIRE
mode.
• The Arc Control regulates pinch effect. At the mini-
mum setting (-10), minimizes pinch and results in a
soft arc. Low pinch settings are preferable for welding
with gas mixes containing mostly inert gases. At the
maximum setting (+10), maximizes pinch effect and
results in a crisp arc. high pinch settings are prefer-
able for welding FCAW and GMAW with CO
OPERATION
CV-INNERShIELD: The CV-INNERShIELD mode
features continuous control from 10 to 45 volts. This
mode was designed for self-shielded flux cored wires
that require tight voltage control.
• The hot Start control is not used in the CV-FLUX
CORED mode.
• The Arc Control regulates pinch effect. At the mini-
mum setting (-10), minimizes pinch and results in a
soft arc. At the maximum setting (+10), maximizes
pinch effect and results in a crisp arc. Most self-
shielded wires work well at an Arc Control setting of 5.
8. hOT START and ARC CONTROL features have
different functions depending on the welding Mode
that is active. Each feature is described under the
welding mode heading. (See Item 6 for specified
Mode Operation)
LOWER CASE FRONT
The output studs, line switch and remote connector
are located on the lower case front.
9. Both STUDS contain "Twist-Mate" connector
inserts.
• The Negative stud is configured to accept the
pass through gas system.
10. The ON-OFF switch is a 3-phase circuit breaker
rated at 100 amps per leg.
11. The METER POLARITY switch is located above
the output connectors. The switch provides a work
connection for wire feeder voltmeters. Place the
switch in the position of the electrode polarity indi-
cated by the decal. The switch does not change
the welding polarity.
12. 6-PIN MS-style connector for remote control.
REMOTE CONTROL of the OuTPuT CON-
TROL and WELD TERMINALS
The EX350ie (CE) has auto sensing of remote output
controls. If after connecting or removing a remote, the
EX350ie (CE) did not configured the way you would
like the local or remote control settings can be
changed by pushing the OUTPUT CONTROL or
WELD TERMINAL button. (A user cannot select
between the 6 and 14-pin MS-style connector.)
CV modes
• The remote will default to the 14-pin MS-style con-
nector remote if a remote is connected. If no
remote is connected to the 14-pin MS-style connec-
tor then the remote will default to the 6-pin MS-style
.
2
connector if a remote is connected to it.
• In all of the CV modes, the WELD TERMINAL con-
trol will default to REMOTE.
