Voltage/ Volts (V)
 Measurement of electrical pressure
 (similar to psi in water pressure)

Amperage/ amps (A)
 Measurement of total number of electrons flowing.
 (similar to gallons as measurement of water flowing)

Wattage/ watts (W)
measurement of the amount of electrical energy or power in the arc.
W=V*A

DCEN
Direct Current Electrode Negative
 Electrode Negative, work positive
 Electrons leave the electrode and go into work
 1/3 heat electrode 2/3 heat on work

DCEP
Direct Current Electrode Positive
 Electrode positive, work negative
 Electrons leave the work and go into the electrode
 1/3 heat work 2/3 heat on electrode

AC
Alternate Current
 Electrons change directions ever 1/120 second
 heat is evenly distributed

CV
Constant Voltage
 The arc voltage remains constant even in arc length and amps increase or decrease

CC
Constant current
 Total welding current (watts) remains the same
 voltage decreases as amps increase
