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 pro-
cess:
- When the TIG AC welding process
is selected, activate automatic
cap-shaping
- The ideal cap for the specified dia-
meter of the tungsten electrode is
formed during welding start-up.
A separate cap-shaping operation
on a test workpiece is not neces-
sary.
- The automatic cap-shaping func-
tion is then reset and deactivated.
The automatic cap-shaping func-
tion 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.
Cap overloading If the cap is overloaded, there is a risk of an excessively large cap forming on the tung-
sten electrode. This will negatively affect the ignition properties.
If the cap is overloaded, the "Electrode overload" indicator will light up on the
control panel.
Possible causes of cap overloading:
- tungsten electrode diameter is too small
- main current value I
1
set too high
- the balance has been set too far towards "+"
Remedy:
- use a tungsten electrode with a larger diameter
- reduce the main current and/or set the balance further towards "-"
NOTE!
The "Electrode overload" indicator is fine-tuned to work with the following tung-
sten electrodes:
TIG AC welding: pure tungsten electrodes
TIG DC welding: ceriated electrodes
For all other electrodes, the "Electrode overload" indicator must be treated as a refer-
ence value.
