OPERATION
B-4
TIG mode
•
The remote will default to the 6-pin amphenol if a
remote control is connected to the 6-pin amphenol
and one of the 14-pin amphenols. If a remote is not
connected to the 6-pin amphenol then the remote
will default to the 14-pin amphenols if a remote is
connected to one of the 14-pin amphenols.
•
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 con-
trol will default to ON.
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 Invertec V350-PRO (CE)
’
s 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 Amphenol lead 75 is pin G, lead 76 is pin F
and lead 77 is pin E.
•
6-Pin Amphenol 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 pro-
duce the current that has been set by the Invertec
V350-PRO (CE)
’
s front panel Output Control.)
•
Remotes of this type offered by Lincoln Electric are
the K857, K812 and K870.
Voltage Control
•
The supply should be an isolated supply. (Not refer-
enced to earth ground, any auxiliary power from the
Invertec V350-PRO (CE) or the welding output) The
supply should be capable of supplying at least 20mA.
•
0 volts supplied to 76 will set the Invertec V350-
PRO (CE) to minimum output for the mode that has
been selected while 10 volts supplied to 76 will set
the Invertec V350-PRO (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 Invertec V350-PRO (CE)
’
s front panel
Output Control.)
Types of Remote WELD TERMINAL Control
•
The Invertec V350-PRO (CE)
’
s Weld Terminals can
be controlled from each of the amphenol connec-
tors. The circuit has a nominal OCV of 15VDC and
requires a dry contact closure (less than 100 ohms)
to activate the output of the Invertec V350-PRO
(CE).
•
14 Pin Amphenols the Weld Terminals are controlled
from pins C (lead 2) and pin D (lead 4). Pin C is posi-
tive.
•
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.
DESIGN FEATURES and ADVANTAGES
•
Multiple process DC output range: 5 - 425 amps
•
Pre-settable welding outputs.
•
Built-in Line Voltage Compensation holds the output
constant over +/- 10% input fluctuations.
•
State of the art inverter technology yields high
power efficiency, excellent welding performance,
lightweight, and compact design.
•
Utilizes microprocessor control.
•
Electronic over current protection.
•
Input over voltage protection
•
Manual reconnect switch located on the back panel
with a clear reconnect door to allow easy determina-
tion of input configuration. The reconnect door is
fastened with 1/4-turn connectors that allow quick
and easy access to the reconnect area. Circuit
breaker protected auxiliary.
•
System Self Configure. The power source analyzes
the remote controls connected to the amphenols
and the desired welding mode to properly determine
the location of trigger and output control.
•
Modular options for easy upgrades
