This function sets the initial start energy
limit. Set this number to a higher setting
than the factory default if needed to
improve starting of large diameter tungsten
electrodes.
0.5 to 1.0 manual start energy setting.
1.2 to 5.0 = max. Incrementing limit.
(See Note)
Note: The machine will try to start the arc at
a start power of 1. If the arc does not
establish it will incrementally increase
the start power and try to restrike up
to the set limit.

OPTIONAL COOL-ARC 35 WATER
COOLER
The optional Cool-Arc 35 water cooler is designed to
operate in communication with the Invertec® V311-T
AC/DC. Refer to the Cool-Arc 35 operator manual for
installation instructions and a complete description of
its operation.
When the Invertec® V311-T AC/DC is powered ON
the Cool-Arc 35 will automatically power ON as well.
The Cool-Arc 35 monitors pressure and temperature
and will adjust the pump speed accordingly to cool the
torch. If a blockage of coolant or loss of coolant is
sensed both the Cool-Arc 35 and Invertec® V311-T
AC/DC will display an error and turn off the Invertec®
V311-T AC/DC’s output.
IMPORTANT: If the Cool-Arc 35 water cooler is
connected to the Invertec® V311-T AC/DC and an
air cooled torch is connected instead of a water
cooled torch the Cool-Arc 35 will sense a coolant
blockage resulting in a cooler error.
In this case the cooler can be turned to the “off mode”
by depressing and holding the push button on the
cooler until the cooler’s display reads “oo”. To turn
the cooler back on you can depress and hold the
Cool-Arc 35 push button until the cooler’s digital dis-
play reads coolant temperature in degrees Celsius.
Turning the Invertec® V311-T AC/DC off and on again
will automatically turn the water cooler back on as
well.
