The processes available are as follows:
MMA Welding with covered electrodes (see
chapter 13))
TIG DC WELDING (see chapter 17)
TIG DC APC WELDING (Active Power Control,
See chapter 16)o 16)
MMA Welding with covered electrodes (see
chapter 13)
Suitable for welding magnetised plates. It avoids
magnetic blow when box welding; it is general-
ly used in maintenance work and in all cases in which
high-penetration welding is not required.
TIG AC + DC (MIX) WELDING (see chapter 16)
To adjust these parameters see chapter 8.3.
This process makes it possible to alternate AC
welding semi-periods with DC welding semi-pe-
riods. The DC process component makes it possible to
obtain greater penetration and faster welding with less
deformation of the workpiece.
TTIG AC XP WELDING (eXtra Power) (See chapter
16).
To adjust these parameters see chapter 8.3.
This process makes it possible to simultaneously adjust
the amplitude of the positive (cleaning) and the negative
(penetration) semi-wave. It is suitable for welding thin
plate corners when the negative semi-wave is set on
MAXIMUM.
TIG AC WELDING (see chapter 16)
To adjust these parameters see chapter 8.3.
The square waveform provides maximum pene-
tration, greater execution speed, and maximum cleaning
and is therefore suitable for all thicknesses.
