penetration. In the position easy the frequency is adjusted automatically according to the balance
adjustment and the used diameter.
•
The electrode does not need to be sharpened except when the currents are too weak < 50A. It is
normal when a ball is formed at the end of the electrode, which size depends on the current
intensity. Use an electrode with pure tungsten.
AC choice guide (recommended indications)
Balance adjustment
The alternative current is used to weld aluminium and its alloys. During the positive wave, oxidation is
broken. During negative wave, electrode is cooling and the parts are being welded, there is penetration.
By modifying the ratio between 2 alternatives through the balance adjustment, you choose either
cleaning or penetration.
Frequency adjustment
In position AC easy, this parameter is adjusted automatically according to the used electrode diameter.
In position AC, it is necessary to adjust manually the frequency : the more penetration and cleaning you
need, the lower the frequency should be. Use preferably the position AC easy.
TIG TSL welding (from 10 to 180 A)
It is system of starting device without high frequency
T = Touch: touch the electrode on the part to be welded
S = Switch : press on the trigger
L = Lift : raise the electrode before a lapse of time of two seconds
Balance : 20% Maximum penetration
50%
60% Maximum cleaning
Before gas
