A: while a step can be of both polarity but it is a level change and it is DC LEVELS
AC means alternating current DC means direct current there is no polarity reversal
The polarity of DC generator can be reversed by reversing the field current as well as direction of rotation
This statement is correct
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
we will have straight polarity and reverse polarity,we can produce the weld with good quality
No. The value and polarity are different.
DC straight polarity
nothing
If you are talking polarity. DC motors automotive application run poss to neg. But any dc motor can reverse by changing polarity.
Polarity

by using multitester
You can plug an AC computer into a DC plug only if you also have an inverter to transform the DC power into the AC power that the computer power supply expects.
You can weld with E6013 using any polarity. Use DC - or AC for thin sheet metal. Use AC if you have arc blow problems. DC - has the lowest penetration DC + has the most penetration AC splits the difference
because they operate on DC
AC means alternating current DC means direct current there is no polarity reversal
