Instruction
- Equipment Overview:
- Point of Operation: The point of operation is at the tip of the welding gun
- Pinch/Nip points: No obvious pinch points
- Unguarded rotating parts: None
- Flying chips/sparks: The welding process creates sparks and extreme heat
- Preparation:
- Complete required orientations, welding training, and sign into the metal shop log
- Ensure TA or staff knows in advance welding will take place
- Inspect the welder and ensure all components are in place.
- Verify that flammable materials are removed from the area.
- Ensure surrounding area is clean, clear, and free of anything that may interfere with operation of the tool
- Set up the welding area with proper ventilation and safety barriers.
- Check the gas supply and adjust the flow rate as needed.
- Operation:
- Ensure material is proper to be welded, has been cleaned and ground to a suitable prepared
- finish, and has been ground or chamfered correctly to accept the weld

- Monitor the weld puddle to ensure consistent penetration and bead appearance.
- Adjust the welder settings as needed for different material thicknesses.
- Finishing:
- Turn off the welder and allow it to cool.
- Remove the material and inspect the weld for strength and appearance.
- Wait 20 minutes of hot work check before leaving the immediate area
