EDF 2

DCEN stands for

• Direct Current Electric Negative

• Direct Current Electrode Native

• Direct Current Electrode Negative

• Direct Common Electrode Negative

DCEP stands for

• Direct Current Electrode Plus

• Direct Current Electrode Positive

• Direct Common Electrode Positive

• Direct Current Electric Positive

DCEP / DCEN is used in

• Arc welding

• Oxy-Acetylene Welding

• Plasma welding

• Gas welding

Disadvantage of DCEP

• 37 percent of heat is on the electrode

• Has good Electrode Life

• Used to weld thin cross sections

• Electrode life is short

Advantage of DCEP

• Used to weld non metals

• Uses Alternating current

• Weld thin section

• Weld thick sections

DCEN used in

• Welding thick sections

• Welding thin sections

• Welding Non metals

• Plasma welding

A property of DCEP

• Low Deposition rate

• Better weld strength

• Weld non metals

• Better Arc cleaning
