Using the High Frequency Arc Stabilizer
t.. Set the welder to the current
recommended
for
the work being done, then turn "On" the welder
and Arc Stabilizer
switches.
2. Turn on the gas and set the flowmeter
to the
recomntended
gas flow
3. Lower the torch toward the work slowly until the
arc is established.
CAUTION." Do not touch the work with the tungsten
electrode_
4. When the arc is established
the torch should be
held so the tungsten tip is positioned at an angle
of approximately
75 degrees to the surface
of
the work.
