ELECTRIC SHOCK can kill.
• Keep the electrode holder, TIG
torch and cables insulation in good
condition and in place.
• Do not touch electrically live parts or electrode
with skin or wet clothing.
• Insulate yourself from work and ground.
• Turn the input line Switch on the Invertec V160-
T “off” before connecting or disconnecting out-
put cables or other equipment.

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 approximately 1/4 turn clock-
wise; until the connection is snug. Do not over tighten.

This unit does not include a TIG torch, but one may be
purchased separately. The Lincoln PTA-9 (K1781-1 or
K1781-3 only with no gas valve) or PTA-17 (K1782-1
or K1782-3) are recommended for use with this
machine for this purpose; 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. (See Figure A.1a)

The ground lead and TIG Torch Twist Mate®
Connector are supplied with the welder. To connect
the cables, turn the PowerSwitch “OFF”. Connect the
torch Twist Mate plug into the DC(-) Electrode/Gas
Output Receptacle on the front of the welder and turn
it clockwise until tight.

Next, connect the work cable to the “+” output terminal
in the same way.
To minimize high frequency interference, refer to
!0278=4 A>D=38=6 0=3 867 A4@D4=2H
=C4A54A4=24 $A>C42C8>=section of this manual for the
proper procedure on grounding the work clamp and
work piece.
The following Lincoln engine drives meet these condi-
tions when run in the high idle mode:
• Ranger 250,305
• Commander 300, 400, & 500
Many engine drives do not meet these conditions (eg
Miller Bobcats, etc). Operation of the Invertec V160-T
is not recommended on engine drives not conforming
to these conditions. Such combinations may overvolt-
age the Invertec V160-T power source.
