Mechanics
ARC welding is the process of creating an electric arc between a base metal and a compatible metal rod, melting and joining the metals at the welding site.
Consumables
ARC welders require flux covered metal rods or sticks that are compatible with the base metal. MIG welders use a spool of flux core wire that is compatible with the base metal.
Projects
MIG welders are primarily used inside shops and factories. If used outside, wind blocks are required. ARC welders are used for larger projects, primarily outdoors.
Advantages
MIG welding is the easiest to learn and has almost no clean up. It can be used for both art and manufacturing and can be used with stainless steel, mild steel and aluminum. ARC welding provides great penetration for thick metals such as steel and cast iron.
Disadvantages
MIG welders require more consumables, such as contact tips and nozzles, that have to be changed when a different metal is used. ARC welders leave rough welds and require patience and practice. Frequent stops to change out rods cause lengthy projects.
