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.
4. ARGON ARC WELDING PROCESS (TIG)
4.1. PREPARING THE WELDING UNIT FOR OPERATION WITH TIG – LIFT
FUNCTION
ATTENTION!
As a protective gas in argon arc welding, such inert gas as argon
(Ar), sometimes helium (He), or a gas mixture, such as 40 % Ar + 60 % He, is
used.
Do not use combustive gases
. The use of other gases is allowed only by
agreement with the manufacturer of the welding unit.
Preparation the welding unit for TIG LIFT operation:
1.
Connect the
TIG torch
into socket
B
(–)
of the welding unit;
2.
Connect the grounding cable into socket
A
(+)
of the welding unit;
3.
Connect the grounding cable to the workpiece;
4.
Connect the power cable of the welding unit to the outlet of the power supply system;
5.
Set gas reducer on gas bottle;
6.
Open the shut-off valve of the gas cylinder. Check the tightness of the connection with the gas
cylinder;
7.
Connect the power cable of welding unit to the outlet of the power supply system;
8.
Set switch
(14)
on the rear panel of the welding unit to position I (switching on);
9.
Switch the button
(4)
to the
TIG
welding position, if the desired welding method has been
skipped, press the button
(4)
again - the methods are switched over and over again;
10.
By holding the button
(3)
for about 5 seconds, you can access the blocked functions of the
welding machine;
11.
Using the buttons
(1)
set the current basic parameter - welding current or parameter of the selected
function;
12.
The device is ready for use.
Enjoy Your work.
