TIG‐LIFT ARC STRIKING FUNCTION
This function is set in this equipment model by default and is designed for
burners with contact arc ignition, without the use of oscillators, and other similar
devices. In contrast to the classical ignition method, TIG-LIFT minimizes the
current surge at the ignition time, and this significantly reduces the destruction of
non-consumable tungsten electrode and its inclusions in the weld (which is a very
negative phenomenon).
Attention!!!
It requires cleaning the product at the arc ignition point.
The method of applying this function is to touch the product with the
electrode, while holding the electrode in this position as much as possible, and
when the user finds himself ready to start welding (for example, put the protective
mask on the eyes and blow the place well with protective gas) then to get started
just start SLOWLY to raise the sharpened electrode tip from the product. The
machine will determine this moment and perceive it as a signal for the welding
process start, thus it will begin to increase the arc current to the set value, the
larger the main operating current, the faster the electrode must be raised,
otherwise it will melt. The welder needs to get used to the optimum speed of the
electrode separation.
4.3 AR
C CURRENT FADE‐IN FUNCTION
This function is necessary to save the electrode life and to some extent the
burner itself, as well as for ease the burner use. It eliminates the formation of the
weld pool initial splashing, and also during the set time for the current smooth rise
[t.uP], you can accurately bring the burner to the required welding location, since
the arc ignition point in especially important products is not always located at the
welding point. Also with you can pre-heat the welding point with this function. By
default, the function value is set to 0.1 seconds. The order of changing the value of
any function in the current welding mode, see cl. 6.1.
4.4 PULSE CURRENT WELDING FUNCTION
This function is intended to facilitate the welding process control in spatial
positions other than the lower one, as well as during non-ferrous metals welding.
The impact occurs directly on the mixing of the molten weld metal and on the
transfer of the drop into the weld pool, and this in turn affects the stability of the
weld formation and the welding process. In other words, this process to some
extent replaces the welder's hand movements, this is especially applicable when
welding in hard-to-reach places. The weld formation shape and quality depends on
the correct function setting, which reduces the likelihood of pores and reduces the
structure graininess, which in turn increases the welded joint strength.
