Welding In Slow Motion

you shoot scalding hot metal out of your ass?

This is arc welding, which is oddly termed imo because all welding may involve arcs of electricity, it is also more commonly known as stick welding. "Stick" being the part melting into the weld, the gas is necessary in order to prevent impurities from getting inside of the actual weld. MIG welding, while I do not know the acronym per se, refers to a machine which shoots a wire out of a "gun" hence the G in MIG I believe. The wire melts and should actually be touching the surface while melting, not dripping into a weld, hence one could assume it is not MIG welding.

honestly it looks like an arc air carbon rod.. :s (which is extemely odd)

i can say its likely not flux OR hard wire (2 most common mig)
