yes Electrode Positive is the same as Reverse Polarity
Shielded Metal Arc Welding (SMAW) offers several advantages, including portability, simplicity, and versatility, making it suitable for various materials and positions. It is also cost-effective, as it requires minimal equipment. However, disadvantages include the production of slag, which requires additional clean-up, and the potential for lower welding speeds compared to other methods. Additionally, SMAW may not be ideal for thin materials due to the heat input and potential for distortion.
arc efficiency=heat developed at anode/total heat developed
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.

The minimum thickness for SMAW welding is about 18 ga. with a steady hand.

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.
