Ac (alternating current) equipment is cheaper because you dont need rectifiers to change current from alternating current to dc (direct current) and there is no arc blow associated with ac (alternating current).
D C means the electron flow is in one direction ( negative to positive or positive to negative). A C constantly reverses itself 60 time a second and because it changes direction at one point there is no flow. D C flow is smooth/steady and can be utilized in either direction - straight or reverse for different applications. Stick welding (SMAW) with D C produces a smoother flow whereas A C tends to create a lot of spatter. Most available electrodes can be used with D C Current. Some can be used with either. A few are for A C only.

The significance of the arc welding process are:-1. Flux Shielded Manual Metal Arc Welding is the simplest of all the arc welding processes.2. The equipment can be portable and the cost is fairly low.3. This process finds innumerable applications, because of the availability of a wide variety of electrodes.4. A big range of metals and their alloys can be welded.5. Welding can be carried out in any position with highest weld quality.6. The process can be very well employed for hard facing and metal deposition to reclaim parts or to develop other characteristics like wear resistance etc.ARSHAD H BHUTTOSALES ENGINEER-LINCOLN ELECTRIC WELDING PRODUCTS
INCONEL alloy 600 is readily joined by conventional welding processes. Welding materials for joining alloy 600 are INCONEL Welding Electrode 182 for shielded metal-arc welding*, INCONEL Filler Metal 82 for gas tungsten-arc and gas metal-arc welding, and INCONEL Filler Metal 82 and INCOFLUX 4 Submerged Arc Flux for the submerged-arc process. Welds made with INCONEL Welding Electrode 182 may have decreased ductility after extended exposure to temperatures of 1000° to 1400°F (540° to 760°).

Manual Metal Arc Welding
The most important equipment you can have is your safety equipment, your gloves, visor and heavy-duty clothing. You have to have some sort of a power source to generate the electricity necessary for arc welding, so I'd say a power source is your most important arc welding equipment.

The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
If you mean companies that manufacture welding equipment: * Miller * Lincoln * Thermal Arc * Esab * Arcon * Hobart * Clarke are just a few.
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
Yes, arc welding does create ozone. It is because the temperatures created during arc welding convert the nearby oxygen to ozone.
Gas Tungsten Arc Welding Gas Metal Arc Welding Flux Cored Arc Welding
Arc welding uses an electrical current to create enough heat to melt metal. Any type of welding that uses an electric arc is technically arc welding. However, most people use the term 'arc welding' to mean shielded metal arc welding (SMAW), or 'stick welding'. SMAW, MIG, and flux core wire welding use the filler metal as both electrode and filler; TIG welding uses an electric arc to heat the base metal and a separate filler rod to add metal to the weld.
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
smaw welding is sheilded metal arc welding
ARC welding uses large amounts of electricity to melt the metal, not a hot flame. So no, LPG cannot be used for ARC welding.
