Getting started
3.1 These are general guidelines for use
and maintenance for your Power Series
unit. Take into account all safety rules and
recommendations first before operation
and service. Do not let untrained person-
nel operate or service equipment in any
way.
3.2 Shielding gas selection.
Do not attempt to operate theTIG func-
tion with out the proper shielding gas!
Proper shielding gas selection is crucial to
satisfactory operation of your TIG machine.
Shielding gas is a special gas or mixture of
gases designed to cover and protect your
weld from contamination from the atmos-
phere while welding and as it cools. Oxy-
gen and other gases from the atmosphere
can infiltrate the weld and make it unserv-
iceable. Do not be fooled by the weld’s ap-
pearance, because many defects are con-
tained inside the weld without the use of
proper shielding gas. The most economi-
cal and available gas is 100% Argon. He-
lium and Argon/Helium mixes are also
available. Helium offers faster weld rates
while Argon offers a more focused cone
and better cleaning action. Do not attempt
to use common shielding gases designed
for MIG welders. These will melt the tung-
sten and contaminate the weld. If you have
never developed a working relationship
with your local welding supplier, then it is
time to make a visit to purchase or lease a
tank of shielding gas. Many sizes of tanks
are available. Choose the size that best fits
your long term needs.
3.3 Regulator/ flow meter selection. You
will need a flow meter/ regulator designed
to be fitted onto your shielding gas tank. It
controls the flow rate of shielding gas into
your Power Series. There are two styles
generally available. The first has two
gauges, one for pressure the other for
flow. The best regulator has a pressure
gauge and a flow meter with a ball that
floats when gas flows. Certain flow meters
can regulate Helium, Argon or Helium/
Argon mixes equally well. However, oth-
ers cannot. It is advisable that a flow meter
be selected that can regulate both.
Always be sure to select the correct
flow meter for the type of shielding
gas that is in use. Never substitute oxygen
or acetylene regulators!

3.4 Regulator/Flow meter connection. Af-
ter connecting regulator safely to tank,
attach hose end to shielding gas inlet .
(see 2.3.5) Firmly clamp and secure hose
end to the unit. Depending upon the flow
meter manufacturer, you may have to cut
and remove the pre-crimped hose fitting to
attach the hose to the shielding gas inlet
barb. Open the tank valve slowly and
gradually increase the regulator flow to
check for leaks.
