4.5 Push button welding process
The selection of the desired welding process TIG welding, electrode welding and
electrode BOOSTER is made with the push button [9], whereby the LEDs
indicate the selected welding process by illuminating.
4.5.1 TIG welding
The setting of the welding parameters for TIG welding is performed as described
in Section 4.5.
4.5.2 Electrode welding
The settings for electrode welding is performed as described in Section 4.5.
The electrode is simultaneously the arc carrier and the additional material. It
consists of an alloyed or non-alloyed core wire and a coating. The coating has
the task of protecting the weld pool from the harmful ingress of air and stabilizing
the arc. It also forms slag, which protects and forms the weld seam. Electrode
welding can be used to weld almost all metals. Electrode welding is a common,
easily handled welding process.
When setting up for electrode welding care must be taken that no TIG torch is
fitted.
If this is not the case the digital display shows the error number “E021”
(see Section 7.3)
4.5.3 Electrode BOOSTER function
The settings for the electrode booster is performed as described in Section 4.5
In this mode the power supply fuse monitoring is switched off. The maximum
welding power emitted by the “TIGER 180” is 150A and with “TIGER 230” 180A.
If a higher setpoint is selected, this is automatically reduced to 150A or 180A.
When setting up the electrode booster function care must be taken that no TIG
torch is fitted. If this is not the case the digital display shows the error number
“E021” (see Section
7.3)
