Front Panel Connections
1) 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.
2) Negative Output Receptacle
When TIG welding, this is where the TIG Torch connects to
your Invertig 201 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.
3) 3 Pin Trigger Connection
This connection is used with TIG torches, which have on/off
triggers on the torch. Your Invertig 201 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.
4) 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.
5) 5 pin Footpedal Connection
this is where the footpedal connects to the Invertig 201. Insert
the connection into the machine and twist the lock ring to lock
into place.
Rear Panel Controls
1) On-Off Switch
This switch controls the input power to your Invertig Welder.
0 is off and 1 is on.
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 flowmeter 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.
Your Invertig welder comes with a gas hose that connects the
TIG welder to the flowmeter. The input gas fitting is located
in the back of the welder.
If you will be welding thick
aluminum castings such as an
aluminum cylinder head, high
purity helium can be used.
When welding thick aluminum
sections like this and using
helium, to achieve added
penetration it should
be welded in DC.
