Your Invertig welder comes with a gas hose that connects the
TIG welder to the 12020-F gas regulator. The input gas
fitting is located in the back of the welder.
It is possible to weld thick aluminum castings with your
Invertig 160DC for cylinder head repair. To do this, an ultra
high purity helium must be used, and exceptional care must
be used to make sure the area to be welded is clean.

HTP recommends the following premium quality tungsten
ground to a high quality finish for use with your Invertig
160DC. All tungsten is 7" long and can be purchased
individually.
2% Thoriated Tungsten (TT2) – red tip - This tungsten is the
most common tungsten currently used. Generally used for
DC welding of steel and stainless steel. Draw back is it has
a low level radiation hazard. Offers good overall
performance.
2% Ceriated Tungsten (TC2) – grey tip – 2% Ceriated
is an excellent substitute for 2% thoriated tungsten and
works excellent with inverter power sources such as your
160DC. More popular for thinner materials because it
requires less amperage to start. Offers a stable arc.
2% Lanthanated Tungsten (TL2) – blue tip – 2% lanthanated
is also an excellent substitute for 2% thoriated tungsten. It
offers good arc starting characteristics and longer life than
2% thoriated.

The electrode should be sharpened to a point with a fine
grinding wheel. If the stone used for sharpening the
electrode is not clean, contaminants could lodge in the
electrode and dislodge when welding. The grinding wheel
used for tungsten electrodes should not be used for any other
materials. When grinding the electrode to a point, a 15 to 30
degree angle is desired. The grinding marks should run
lengthwise with the point, opposed to in the direction of the
diameter. To prevent spitting the “point” of the tungsten into
the weld, we recommend you slightly flatten the point of the
tungsten just enough to remove the sharp point.
The HTP Tungsten Sharpener is an excellent tool for
precisely sharpening tungsten electrodes without any fear of
contamination.
