1.
Insert the plug of the grounding cable into socket B (-) of the welding unit.
2.
Connect the grounding cable to the workpiece.
3.
Connect the jumper cable not less than 16 mm
2
in cross-section area to socket A
(+) of the welding unit and to the power terminal of the electrode wire feeding unit,
which may be marked diversely, depending on the design of the specific wire
feeding unit.
4.
Connect the welding torch for semiautomatic arc welding to the electrode wire
feeding unit.
5.
Connect the pressure reducer to the fitting of the cylinder with CO
2
or Ar + CO
2
protective gas.
6.
Connect the gas hose to the pressure reducer of the gas cylinder and the fitting of
the electrode wire feeding unit. The method of connection may be arbitrary.
7.
Open the shut-off valve of the gas cylinder. Check the tightness of the connection
with the gas cylinder.
8.
Connect the electrode wire feeding unit to the power supply system (if the unit is
designed for independent power supply).
9.
Switch on the electrode wire feeding unit by using the corresponding power switch
of the unit.
10.
Connect the power cable of the welding unit to the outlet of the power supply
system.
11.
Set switch 7 on the rear panel of the welding unit to position I (switching on).
12.
Press button 5 and hold the button not less than 5 s to select the semiautomatic arc
welding process (MIG/MAG). The display of the welding unit will blink, warning
the operator that the unit is ready to switch to the next welding process. If the
semiautomatic arc welding process has been missed in the process of selection,
press button 5 again for sequentially selecting the welding process required.
13.
Set the specified welding voltage by buttons 3.
14.
Set the specified electrode wire feed velocity by the corresponding adjusting
potentiometer of the electrode wire feeding unit.
If required, perform the additional functions specified for the semiautomatic arc welding process
(see Section 6.1).
Do not forget to provide the supply of protective gas. If you have no experience in setting
optimal gas pressure for welding the specific parts, first set the pressure so that it exceeds
the expected optimal pressure by about 0.2 MPa. In this mode, the increased pressure will
not affect the welding process and will only induce the increased consumption of
protective gas. In the future, fulfill the general instructions concerning semiautomatic arc
welding. For welding with any wire diameter in the range of 0.6 … 1.2 mm, set the
medium electrode wire feed velocity of 7 … 10 m/min and the medium welding voltage
of about 19 V. Notwithstanding that these parameters are not optimal, they are sufficient
for welding if the stable and uniform wire feed is provided. In order to achieve better
results, set the optimal welding voltage, by buttons 3, and electrode wire feed velocity
according to the general instructions on semiautomatic arc welding. Remember that the
parameters to be set are different for different welding processes.
