OUTPUT CONNECTIONS

WARNING
ELECTRIC SHOCK can kill.
• Insulate yourself from work and
ground.
• Turn the input line Switch on the
Invertec® V311T AC/DC "off" before
connecting or disconnecting output
cables or other equipment.
• Keep the electrode holder, TIG torch and cable
insulation in good condition and in place.
• Do not touch electrically live parts or electrode
with skin or wet clothing.

OUTPUT AND GAS CONNECTION FOR
TIG WELDING (FIGURE A.1)
The TIG Torch Twist-Mate and work cable Twist-Mate
Connectors are supplied with the welder. To connect
the cables, turn the Power Switch "OFF". Connect the
torch cable Twist-Mate plug into the DC(-)
Electrode/Gas Output Receptacle on the front of the
welder and turn it clockwise until snug,(Do not
Overtighten). This is a quick connect terminal and also
provides the gas connection for the shielding gas to
the torch.
WARNING
To avoid receiving a high frequency shock, keep
the TIG torch and cable Insulation in good condi-
tion.
___________________________________________

WORK CABLE CONNECTION

Next, connect the work cable to the "+" output terminal
in the same way.
To minimize high frequency interference, refer to
Machine Grounding and High Frequency
Interference Protection section of this manual for the
proper procedure on grounding the work clamp and
work piece.

INSTALLATION
This unit does not include a TIG torch, but one may be
purchased separately. The accessories section of this
manual lists a number of Lincoln Electric TIG torches,
and TIG Torch Starter Packs that are recommended
for use with this machine; however, any similar TIG
torch can be used. To attach the Twist-Mate Plug to a
Lincoln Torch, slide the rubber boot onto the torch
cable (enlarge the boot opening if necessary), screw
the fitting on the torch cable into the brass connector
snugly and slide the boot back over the brass connec-
tor.

OUTPUT CONNECTION FOR STICK
WELDING (FIGURE A.2)
First determine the proper electrode polarity for the
electrode to be used. Consult the electrode data for
this information. Then connect the output cables to
the output terminals corresponding to this polarity.
For instance, for DC(+) welding, connect the electrode
cable (which is connected to the electrode holder) to
the "+" output terminal and the work cable (which is
connected to the work clamp) to the "-" output termi-
nal. Insert the connector with the key lining up with
the keyway, and rotate clockwise; until the connection
is snug. Do not over tighten.
