3. 2. TYPES OF ARC WELDERS
A.C. and D.C. (alternating current and direct current)
and (Non-generator type that produces both A.C. & D.C. current)

4. 3. Define Electrode
A core of wire covered with flux.

4. Purpose OF Flux
Provides a gaseous shield and slag coat that
protects the weld from gases in the air.
