to make sure the moisture is out of the rod.
yes Electrode Positive is the same as Reverse Polarity
arc efficiency=heat developed at anode/total heat developed
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).

The minimum thickness for SMAW welding is about 18 ga. with a steady hand.
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.

The main difference between these two types of welding is that GTAW uses gases to create the weld whilst SMAW uses an an electrical current. Both are very popular welding processes.
Advantage of smaw :*equipment is relatively inexpensive Equipment is portable because the welding machine can be powered with gasoline or diesel powered w/ engines.
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
