- Preparatory phase:
a) Preparation of the edges to be welded.
The preparation of the edges varies according to the thickness of the material to be
welded, the welding position, the type of joint and the working requirements. However,
it is always advisable to work on clean parts, free from oxide, or without rust or other
substances that could damage the weld.
The edges can be prepared with "U" section calking for a weld without rewelding; with
"X" section calking when rewelding of the reverse weld is needed.
- Table for preparing "U" shaped edges:
b) Choosing the electrode.
- The choice of the electrode diameter depends on the thickness of the material, the
type of joint and the welding position.

When welds in "position" are needed, the pool tends to slip due to gravity, so it is
recommended to use electrodes with a small diameter, making a series of passes. For
electrodes with a large diameter, high welding currents are needed, which provide
sufficient heat energy.
c) Setting the welding current.
- The current stability of the generator allows working at low values and in particularly
