Type of weld groove, which piece is beveled, angle of bevel, root opening size, effective throat size, length and pitch of weld, shape of weld face, how the completed weld is to be finished, size of weld, depth of weld penetration, process to be used or

What do the letters CC and CV stand for?

Constant current and constant voltage

What must be done before you change polarity on a welding machine?

Welding must be stopped and the electrode insulated from the circuit

List three methods of attaching a workpiece lead to a worktable or workpiece.

Bolted on lug, magnet, spring clamp, C-clamp

List 2 purposes of an electrode covering.

1. Add filler metal to the weld. 2. Create a protective gas shield 3. Create a flux to clean impurities 4. Create a hard slag covering to protect the molten bead as it cools
