Front Panel Connections

1) Negative Output Receptacle

When TIG welding, this is where the TIG Torch connects to
your Invertig 160DC Welder. That’s right, we said the TIG
Torch. This is called straight polarity, with the torch
negative and the work positive. When using your Invertig
Welder to TIG weld, all work will be done in straight
polarity.

When Stick Welding Direct Current Electrode Negative
(DCEN), the optional electrode holder will be plugged into
the negative output receptacle. When Stick Welding Direct
Current Electrode Positive (DCEP), the ground cable will
be plugged into the negative output receptacle.

To install a cable into the negative output receptacle, insert
the male end of the cable into the negative output receptacle
and twist clockwise until snug.

2) 3 Pin Trigger Connection

This connection is used with TIG torches, which have
on/off triggers on the torch. Your Invertig 160DC comes
standard with a footpedal which has the on/off function
built into the pedal, so an on/off trigger on the TIG torch is
not necessary. Therefore, this connection is not used.

3) Gas Output Connection

This is where you connect the gas fitting from the
TIG Torch. The gas output is controlled by the solenoid
valve, which is mounted inside the welder. The gas fitting
on your Invertig 160DC is a 1/4 BSP male connection.

4) 5 Pin Footpedal Connection

This is where the footpedal or the torch mounted hand
amperage control connects to the Invertig 160DC. Insert
the connection into the machine and twist the lock ring to
lock into place.

5) Positive Output Receptacle

When TIG welding, this is where the ground cable connects
to the front of the TIG Adapter. That’s right, we said the
ground cable. This is called straight polarity, with the torch
negative and the work positive.

When Stick Welding Direct Current Electrode Negative
(DCEN), the ground cable will be plugged into the positive
output receptacle. When Stick Welding Direct Current
Electrode Positive (DCEP), the electrode holder will be
plugged into the positive output receptacle.

To install a cable into the positive output receptacle, insert
the male end of the cable into the positive output receptacle
and twist clockwise until snug.

Rear Panel Controls

1) On-Off Switch

This switch controls the input power to your Invertig
160DC Welder. 0 is off. If the switch is set up to operate on
220-volt power, then rotating the switch to the right will turn
the machine on to operate on 220 volt power. It the switch is
set up to operate on 110-volt power, then rotating to the left
will turn the machine on to operate on 110-volt power. The
switch can only be turned one way at a time. (See electrical
connection)

When you turn the machine on, the power indicator lamp
(#1) will be illuminated green on the front panel of the
welder. This is an indication your Invertig 160DC is on and
ready for use.

Shield Gas

TIG welding requires a shield gas of 100% Argon.
A shield gas is used to keep the surrounding atmosphere
from coming in contact with the molten weld puddle. The
correct flow rate is enough gas to shield the molten weld
puddle and protect the tungsten electrode. Any greater flow
rate is a waste of shield gas. Usually, the flow rate will be set
anywhere between 15 and 30
cubic feet per hour (cfh).

Use a gas flowmeter such as
HTP Part #12020-F which
is compatible with Argon
cylinders and has a barbed
fitting for the delivery hose.
Connect a gas hose to the
gas fitting at the rear of the
machine and to the barbed
fitting on the regulator.
