OPERATION
b-10
DIP Switch 5: Low OCV Enable
This controls the OCV of the machine. When the
DIP switch is OFF the OCV is set to the normal level
as stated in the manuals for the machines. When
the DIP switch is ON the OCV is reduced to 20V.
This low OCV mode was created for the Australian
markets and should only be used as required by
these Australian specifications. The low OCV will
somewhat reduce the starting performance of the
machine when dirt, rust, and/or slag is present on the
work piece.
DIP Switch 6: European/USA Machine
Configuration
This configures several functions of the V160 as
required by the European and USA markets. For the
European market it is OFF and for the USA market it
is ON.
Specifically, this configures the operation of the TIG
slope timers, remote control, and trigger. However,
this configuration also depends on the position of
DIP Switch 1 which selects the machine type. This
setting can be changed but only if the following func-
tions are clearly understood.
(DIP Switch 1 = OFF)
In TIG welding mode, the following conditions can
exist.
• European Machine Configuration (DIP Switch 6 =
OFF)
The TIG slope functions are always enabled. After
the arc is started the output current will be increased
(upslope) to the welding current. At the end of the
weld the current will be decreased with the downs-
lope function. Using a "foot pedal" remote control is
not recommended with this setup.
A trigger is always needed to turn ON the output of
the machine.
• USA Machine Configuration (DIP Switch 6 = ON)
The TIG slope functions depends on the possible
connection of a remote control.
• No remote control connected. The TIG slope func-
tions are enabled. After the arc is started the output
current will be increased (upslope) to the welding
current. At the end of the weld the current will be
decreased with the downslope function.
• Remote control connected. The TIG slope functions
are disabled for the 2 step trigger mode. If slopes
are needed a foot pedal remote control can be
used. The TIG slope functions are enabled for the 4
step trigger mode.
A trigger is always needed to turn ON the output of
the machine.
