Remote Control Of The Output Control And Weld Terminals - Lincoln Electric INVERTEC V350-PRO CE 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 con-
trol 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 main-
tained 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 set-
tings between 0 and 5 regulate the arc initiation cur-
rent. A setting of 5 results in the most positive arc ini-
tiation. 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 th V350 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 sole-
noid 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 weld-
ing 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
preferable for welding FCAW and GMAW with CO2.
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 Invertec
remote output controls.If after connecting or removing
a remote, the Invertec
ured the way you would like the local or remote con-
trol settings can be changed by pushing the OUTPUT
CONTROL or WELD TERMINAL button. (A user can-
not select between the 6 and 14-pin MS-style connec-
tor.)
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 connector then
the remote will default to the 6-pin MS-style connec-
tor if a remote is connected to it.
• In all of the CV modes, the WELD TERMINAL con-
trol will default to REMOTE.
