The machine calculates pulsing in such a way that, at a constant set differential of
pulses, average level of arc current is maintained at the level of set base arc current
value of 100A (i.e. equal to the set value), in order to keep the resulting average heat
input into the weld at a constant level of 100A,
but the stability of the welding
process and the mixing of the weld pool will change
. This is necessary in the
situation, when a user has reduced base current and provided maintenance of stable
welding process using pulses—thus, decrease of heat input can also be clearly
determined by comparison with initial base current.
These parameters are set differently in different situations in accordance
with welding operator’s requirements. See Clause 6.1 for sequence of changing the
value of any function in the current welding mode.
5. SEMIAUTOMATIC METAL INERT/ACTIVE GAS WELDING
(MIG/MAG)
Attention!
In the most general case, carbon dioxide “СО2” is used as shielding gas
for welding of ferrous metals, and aluminium is welded only using inert gases, such
as argon “Ar” and sometimes expensive helium “He”. As an alternative option for
stainless and high‐alloy steels, mixtures with different ratios are often used, such
as “80%Ar+20%CO2”. Other gases can only be used upon approval of the
equipment manufacturer.
Attention!
Since the machine is equipped with a standard torch KZ‐2 slot of EURO
type, the user can purchase a torch at his/her own discretion in the future.
