Cap shaping and cap overloading
Cap-shaping
(2) (1)
(1) Before ignition
(2) After ignition
On MagicWave power sources, an
automatic cap-shaping function is
available for the TIG AC welding
process:
- When the TIG AC welding pro-
cess is selected, activate auto-
matic cap-shaping
- The ideal cap for the specified
diameter of the tungsten elec-
trode is formed during welding
start-up.
A separate cap-shaping opera-
tion on a test workpiece is not
necessary.
- The automatic cap-shaping
function is then reset and deac-
tivated.
The automatic cap-shaping
function has to be activated
separately for each tungsten
electrode.
NOTE!
The automatic cap-shaping function is not necessary if a sufficiently large cap
has already formed at the tip of the tungsten electrode.
