A few broad areas for your consideration-
ELECTRICAL safety- when using any electrical equipment
THERMAL safety- when working with hot items
EYE and FACE safety- working with things that spatter. or produce ultraviolet light that can burn your eyes
RESPIRATORY safety- breathing fumes from welding is very unhealthy
FIRE safety- you can set things on fire
MATERAIL HANDLING safety- cuts and strains/sprain when moving heavy or sharp items
Mig
CO2 and O2 can not be used in the same time for shielding gas in MIG welding, it would create too much oxidation of the molten metal.
See preceding question re: Mig welding.
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
metal inert gas (MIG) welding
Mig
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
metal inert gas (MIG) welding
Flux core is a type of MIG welding.... please kind of know what your talking about before you ask a question.... Gas assisted solid mig wire welding is neater and cleaner. There are two types of flux core mig welding that you are talking about. 1. Gasless flux core mig wire 2. Shielded flux cored welding wire, uses a shielding gas as well. Most likely you are talking about the gasless mig wire. look here for more info: www.learn-how-to-weld.com/gasless-mig-wire.html
DCEP for standard Mig. DCEN for Flux Core
MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
Gas Metal Arc Welding Most folks call it MIG
A tubular or wire cored electrode is used for both MIG and MAG welding. These can be purchased online at places like AGA.com.
Wire feed speed in MIG welding is calculated by multiplying the welding current by the wire feed rate. This formula helps determine the speed at which the welding wire is fed into the weld pool during the welding process.
