welding operator to separate (detach) the electrode from the work piece without
risk to burn his eyes with accidental arc striking. Once the electrode is separated
from the work piece, the process of welding can be readily resumed.
3.5 FUNCTION OF SLOPE ADJUSTMENT FOR A CURRENT‐VOLTAGE CURVE
This function is primarily designed for convenient welding using electrodes
with different types of coating. By default, current‐voltage curve slope [CVS] is set
to 1.4V/A, which corresponds to the most commonly used electrodes with rutile
coating (АНО‐21, МР‐3). For more convenient work with basic‐coated electrodes
(УОНИ‐13/45, ЛКЗ‐70), it is recommended, although not required, to set the slope
[CVS] to 1.0V/A. On the other hand, cellulose electrodes (ЦЦ‐1, ВСЦ‐4А) even
require for setting the slope [CVS] to 0.2...0.6V/A, and sometimes it is also
necessary to rise trigger level of the Arc Force Function [u.AF] up to 18V. See
Clause 6.1 for sequence of changing the value of any function in the current
welding mode.
3.6 SHORT ARC WELDING FUNCTION
This function is especially important for overhead welding, when very long arc
is undesirable. For this purpose, the machine provides the possibility to set the
Short Arc function [Sh.A] to “ON” position. By default, it is set to “OFF” position.
See Clause 6.1 for sequence of changing the value of any function in the current
welding mode.
3.7 FUNCTION OF AN OPEN‐CIRCUIT VOLTAGE REDUCTION UNIT
When performing welding works in vessels, tanks and applications requiring
for enhanced electric safety system, one can enable the function of open‐circuit
voltage reduction.
In 0.1s after the electrode is detached from the work piece, the voltage on the
source terminals drops to a safe level below 12V.
In order to enable this function, an open‐circuit voltage reduction unit [BSn] is
required. This unit is envisaged in this equipment model, but is set to “OFF”
position by default, i.e. disabled, since it is known, that enabling of any such
function results in a somewhat worse arc striking. See Clause 6.1 for sequence of
changing the value of any function in the current welding mode.
3.8 PULSED CURRENT WELDING FUNCTION
This function is designed to facilitate control over the welding process in
spatial positions other than downhand position, as well as during welding of
non‐ferrous metals. This function affects directly weld metal dilution and metal
