MIG welding is almost always in what polarity?

DCEN
DCEP
AC
No polarity

The correct answer is: DCEP

MIG welding stands for Metal Inert Gas welding, and is usually done with direct current - typically either direct current electrode negative (DCEN) or direct current electrode positive (DCEP), depending on which electrode should be positively charged for that particular weld. AC or alternating current is not used for MIG welding. No polarity would not allow the welding process to occur.
