proper machine settings.
3. Set the OUTPUT RANGE dial to the appropriate
setting for the electrode you are using. Refer to
IM -528 with the TIG module or refer to Table B.2
for AC TIG welding.
4. Set the POLARITY SWITCH to the desired polarity.
5. Do not AC TIG weld on the 250 AC range setting.
The output current may exceed the rating of the
RANGER 9.
6. Start the arc and begin welding.
