Preparation should include

• inspecting welding leads and electrode holders for safety
• ensuring the material is properly grounded
• preparing and cleaning the metal by filing, grinding, or using a wire brush
• inspecting electrodes
• determining the welder type and electrode to be used
• setting up welding equipment
• adjusting the welder for voltage and polarity for the material being welded
• determining ground clamp positioning and attachment.

Process/Skill Questions:

• Why is metal preparation important to ensure a good weld?
• How does the electrode selection affect the way the metal is prepared?
• How can frayed welding leads be a hazard?
• How are welding supplies, including electrodes, properly stored?
• How can one determine whether a welder will be able to perform a weld or another machine should be selected?
• Why does metal have to be cleaned to ensure a proper ground?
