POST GAS AND PREGAS ADJUSTMENT
PREGAS (0 TO 25 SEC.)
The pregas is used, before arcing, to purge the torch and the area around the welding bead.
It also improves arcing consistency.
Advice : the longer the torch is, the longer pregas setting should be. (0.15 s/m of torch)
POSTGAS ADJUSTMENT (3 TO 20 SEC.)
The parameter sets the time while gas is still flowing after arc shutdown. It protects the weld
pool and the electrode against oxidisation when the metal is cooling down.
Advice: Increase the duration if welding in a dark area..
(Base : 25A=4sec - 50A=8sec - 75A=9sec - 100A=10sec - 125A=11sec- 150A=13sec)
ADJUST SETTINGS
The switches for post-gas & pre-gas are setted by which are located on the main PCB inside
the EXATIG. It is necessary to remove the PCB in order to access. Identify the post gas &
Pregas switch to modify the settings according the needs.
