Title: Prepare equipment and materials for GMAW operations, adhering to all safety requirements, industry recommended practices, and instructor guidelines.
Course: Agricultural Fabrication and Emerging Technologies (18404) > Section: Performing Gas Metal Arc Welding (GMAW) Operations

Preparation should include

- storing, handling, and installing high-pressure gas cylinders
- determining the welder type, electrode, wire type, diameter, and gas to be used
- setting up welding equipment
- adjusting the welder for proper electrode stick-out, voltage, polarity, flow rate, and wire-feed speed required for the material being welded
- determining ground clamp positioning and attachment.

Process/Skill Questions:

- How is GMAW wire classified?
- Why is GMAW wire copper in color?
- What is the line pressure for gas shielding when welding steel?
- What resources are available to determine voltage and wire-feed speed?
- When you increase voltage, what else will need to be increased? Why?
- What is the proper gun angle to the metal when performing GMAW operations?
- What are common problems to look for if the wire does not feed properly?
