Gas output begins; the high frequency is then generated to start the arc, as well as
the power source output DC voltage (AC voltage is generated only if output
current in present).
Correct?
♦
After approximately three seconds, the output voltage and high frequency are no
longer generated (TIG operation stops if there is no current at the power source
output after start) and the post-gas stage begins.
NO (see 3.3.6, 3.3.7).
YES
Use the knob (AA) to set the current based on the welding you intend to perform.
Move the torch near the workpiece and press the torch trigger.
♦
Begin welding. Turn the knob (AA) or the torch potentiometer to obtain the
