If it is required to reduce heat input to the weld, as in welding thin parts, the welding current should be
decreased by performing the standard setting operations. In this case, current pulse parameters will be
adjusted automatically according to the set welding current, and the operator can control the reduction of
the heat input, as compared with the heat input at the initial welding current, by simultaneously varying
the current pulse amplitude and duty cycle.
The aforementioned parameters should be set differently for different welding processes, depending on
the requirements of the operator.
Operations required to set these parameters for the current welding process are described in Section 6.1.

ATTENTION!
As the shielding gas during welding of carbon steel, carbon
dioxide "CO2" is used, it is the cheapest option of protective gas, it is not widely
used due to the large amount of fumes and welding dust, as well as spatter, the
most common mix is used in the proportions "Ar" (82%) "CO2" (18%). When
welding aluminum, inert gases are used - argon "Ar", sometimes more expensive
helium "He". For stainless steel and high-alloy steels mixtures with variable
proportions of "75% Ar + 25% CO2" are commonly used. The use of other gases
only after consultation with the manufacturer of the device.
ATTENTION!
As in the welding unit a standard KZ-2-euro connector for a
welding torch is used, any welding torch can be purchased at the option of the
user
