When the welding gun lead is connected to the positive terminal, the polarity is designated as ______________, previously called reverse polarity.

____________ yields a stable arc, smooth metal transfer, relatively low spatter, good weld bead characteristics, and great depth of penetration for a wide range of welding currents.

With all variables held constant, arc voltage is directly related to ________________.

Which is not true for any specific value arc voltage:

At ___________ travel speeds, the welding arc impinges on the molten weld pool, reducing the effective penetration.

An increase in the electrode extension results in ___________ in its electrical resistance; the filler metal will deposit a narrow, high-crowned weld bead.

Electrode orientation affects bead shape and penetration to _____________ arc voltage or travel speed.

When the electrode points opposite from the direction of travel, the technique is called _________ welding with a drag angle.

When the electrode points in the direction of travel, the technique is called ___________ welding with a lead angle.

A larger electrode requires _____________ minimum current than a smaller electrode for the same metal transfer characteristics.
