ARC WELDING PRINCIPLES
A consumable electrode is connected to a high voltage supply which creates
an electric arc between the electrode and the workpiece. The arc is used to
create the required heat to turn the metal into a molten state. The electrode is
also used as a filler.
The shielding gas is created from the flux within the welding rod (electrode).
When using the welder outside, you may need to take measures to erect a
wind break to make sure the shielding gas is not blown away, thereby leaving
a poor quality weld.
PREPARATION FOR USE
FITTING THE WELDING ROD
1. Select the appropriate welding rod, and insert it into the welding rod
holder.
• It should be approximately the same thickness as the workpieces
being welded.
PREPARING THE WORKPIECE
The area being welded should be perfectly clean. Any coating, plating or
corrosion must be removed, otherwise a good weld will be impossible to
achieve.
