Contradiction in terms. If its "non-fusion" then it isn't welding. You probably mean brazing.
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
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.
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.
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.
Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential. The heat and electrical conducctivity of the gas at the arc temperature are a huge factor as well.
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.
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
