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.

5. SEMIAUTOMATIC ARC WELDING PROCESS (MIG/MAG)
The welding unit can be used as a power source for semiautomatic arc welding. To be operated
according to this welding process, the welding unit has a special voltage-current characteristic as a
function of the unit output current against the voltage at the output terminals of the unit. As an
external electrode wire feeding unit, any independent electrode wire feeding unit with an integrated
special power supply for the unit driving motor may be used. According to the other variant, the
electrode wire feeding unit can be designed for power supply from the welding unit. This variant is
not recommended, as in this case, the electrode wire feeding unit cannot provide uniform and stable
wire feed.
