Title: Set up and attach a work clamp (i.e., ground), and adjust the GMAW welder to tune for proper electrode stickout, voltage, polarity, flow rate, and wire-feed speed required for the substrate being welded.
Course: Auto Body Technology I (20117-I) > Section: Practicing Metal Welding, Cutting, and Joining

Procedures should include

- determining the correct welder type, electrode, wire type, diameter, and gas to be used in a specific welding situation
- setting up welding equipment
- adjusting the welder to “tune” for proper electrode stick-out, voltage, polarity, flow rate, and wire-feed speed required for the material being welded
- determining the work clamp (e.g., ground) location and attaching

following manufacturer guidelines and recommendations.

Process/Skill Questions:

- What is the line pressure for shielding when welding steel?
- When increasing amperage, what else needs to be increased? Why?
- What is the proper angle of the gun to the metal?
