first
set the shielding gas flow.
prepare the tungsten electrode.
apply the machine settings (polarity and amperage).
assemble the torch.
last

Explanation:

GTAW (Gas Tungsten Arc Welding) setup follows a logical sequence: first prepare the tungsten electrode (core component of the torch), then assemble the torch with the electrode, apply machine settings (polarity/amps) to configure the power source, and finally set shielding gas flow to protect the weld area.

Answer:

1. Prepare the tungsten electrode.
2. Assemble the torch.
3. Apply the machine settings (polarity and amperage).
4. Set the shielding gas flow.
