Base
START CURRENT = initial current. It acts only with switched
on 4T function. This function is used for adjusting the initial
current in order to properly initiate electric arc.10-220 A
PEAK CURRENT. This function acts only at switched on
pulsation It is used for switching the current between main
current (CURRENT) and low current during pulsation welding.
10-220 A
BASE CURRENT = arc supporting current in PULSE mode.
10-220 A
Final
FINAL CURRENT = It acts only with switched on 4T function.
This function is used to select proper end current of welding in
order to extract the fusion weld properly.
10-220 A
PULSE FREQUENCY = this function means the frequency in
time unit (for impulse welding)
0,5-5 Hz
DUTY CYCLE = pulse fulfilment; the ratio of the pulse time
duration to the pulse period.
10-90%
POST GAS = gas access time after the decay of the electric arc
is adjusted in second intervals. The adjusting function for this
time value is significant for the fused fusion weld which has to
be cooled and protected against oxidation after finishing the
welding process. 1-10 s
CLEAN WIDTH = percentage difference of the time between
positive and negative current direction in one welding current
period -5 / +5
WIG/TIG = in opposition to the metals welding in MIG/MAG
gas curtain, during welding with WIG method, the electric arc
appears between the infusible wolframic electrode and the
welded material. For the protection of the wolframic electrode
and the fusion weld, the neutral gases as argon or helium
or non-oxidizable gas mixtures are used. Welding with WIG
method may be used for all welded metals. Selection of the
type of current, polarization and curtain gas depends on the
welded metal type. This device uses the welding handle (burner)
– WIG, which is equipped with the wolframic electrode, argon
curtain gas release nozzle and the fluxing agent, depending
on the welded material. Our welding technology specialists
recommend red wolframic electrodes for steel and precious
steel, green ones for aluminum, black ones for steel and cast
iron, gold and grey ones for universal applications. Depending
on the metal plate thickness, the following wolframic electrodes
are recommended:
thin metal plate 0.5-1 mm
metal plate, thickness of 1-6mm
thick metal plate - 6 mm
= electrode 1.6 mm = electrode 2.4 mm = electrode 3.2 mm
In case of gas nozzles we recommend the size of 7 in within
the area of universal applications and size of 5 within the area
of precise welding.

MMA = electric arc welding (E-Hand/MMA) is one of the
earliest methods of metal objects welding; it is also in use
nowadays. Welding energy is generated by the electric arc
between the consumable electrode and welded element.
“4T/2T” selection button: Selecting “4T/2T” procedure
functions, TIG welding divides into “2T” action (non-self lock)
and “4T” action (self lock)
AC/DC = while using inverter, it is possible to weld with direct
current (DC) or alternate current (AC). Thanks to this, the
machine may weld almost every metal. The alternate current
is used for welding light metals (as aluminum or titanium). For
welding most of other metals (as constructional steel and free-
machining steel) we use direct current.
