Which items should be checked in a pre-weld inspection for TIG welding?

• A. Cables, torch, gas lines, and tungsten condition
• B. Filler rod that matches base metal
• C. Work area lighting
• D. Ambient temperature

Answer: (A)

Before striking an arc in TIG welding, you verify the equipment that carries current and provides shielding is in good condition. Check the cables and connectors to make sure there’s no damage that could cause arcing or current loss. Inspect the torch itself and the tungsten electrode; a clean, properly seated tungsten and the right shape for the job helps maintain a stable arc and prevents contamination of the weld. Examine gas lines and hoses for leaks and ensure the shielding gas is flowing at the correct rate so the weld area stays protected from air. When all these are sound, you’re set for a clean weld with proper shielding and arc stability.

Filler rod matching the base metal matters for the final weld properties, but that’s a material choice made for the weld—not a part of the equipment readiness you check during a pre-weld inspection. Lighting and ambient temperature can affect comfort or heat management, but they aren’t part of the essential equipment check for the weld setup.
