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.

Yes, pneumatic welding machines are possible and are used in specific applications where traditional welding methods may not be suitable. These machines utilize compressed air to drive welding processes, typically in industries that require lightweight and portable equipment. Pneumatic welding is often employed for tasks like spot welding or in environments where electrical hazards are a concern. However, the technology may have limitations compared to conventional welding methods in terms of depth and material thickness.
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).
Two common types of AC arc welding machines are the transformer-based machines and inverter-based machines. Transformer-based machines use a transformer to step down the voltage and provide a stable arc, making them suitable for various welding applications. Inverter-based machines, on the other hand, use advanced electronics to convert the input power into a high-frequency output, allowing for greater efficiency, portability, and control over the welding process. Both types are widely used in different welding scenarios based on their performance and application needs.

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.

Constant current arc welding machines are primarily used in processes such as Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW or TIG), and some variations of Gas Metal Arc Welding (GMAW). These machines maintain a consistent current level to ensure stable arcs, which is especially important for manual and precise welding applications. SMAW and GTAW benefit from this characteristic, as they allow for better control over the weld pool and electrode.

SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
