OUTPUT CONNECTIONS
ELECTRIC SHOCK can kill.
• Keep the electrode holder and
cable insulation in good condition.
• Do not touch electrically live parts
or electrode with skin or wet cloth-
ing.
• Insulate yourself from work and ground.
• Turn the input line Switch on the Invertec V160-
S “off” before connecting or disconnecting out-
put cables or other equipment.
-----------------------------------------------------------
The Work Cable and Electrode Cable are supplied
with the welder. To connect the cables, turn the Power
Switch “OFF”.
OUTPUT AND GAS CONNECTION FOR
TIG WELDING (FIGURE A.1)
This unit does not include a TIG torch, but one may be
purchased separately. The Lincoln (K1781-7 PTA-9FV,
K1782-11 PTA-17FV) and (K1782-6, K1782-8 PTA-
17V) 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 fit-
ting on the torch cable into the brass connector snugly
and slide the boot back over the brass connector.
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 key way, and rotate approximately 1/4 turn clock-
wise; until the connection is snug. Do not over tighten.

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-S
is not recommended on engine drives not conforming
to these conditions. Such combinations may overvolt-
age the Invertec V160-S power source.
