2 basic types, Gas shielding, and flux shielding. Gas shielding comes from compressed tanks of inert gas such as argon. these gases are pumped through the welding hose and over the weld pool. The flux type protects the weld by covering it in a layer of slag that prevent it from being contaminated by the surrounding air.
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
V= 0.05 i + 10 for mmaw welding v= 0.05 i + 20 for tig welding
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).
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.

Welding machine companies are important, because welding machine manufacturers like Artech Welders, Dynarc Systems, Crystal Electrodynamix are provides all types of welding machines for various business firms.
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.

Who makes the best welding machines is quite subjective. Some of the best machines are said to be made by Lincoln Electric while others prefer Miller Electric machines.

SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
Depending upon the type of welding machine, its cost varies from Rs50.000 to more than Rs 1,00,000. Manufacturers like Artech welders, Roteckweld offers welding machines at affordable cost.
Welder is a tradesman who specializes in welding materials together. Welding is a process that joins materials. Hobart Welders is a brand of welding machines. And yes, they are good.
