4. ARGON ARC WELDING PROCESS (TIG)
4.1. PREPARING THE WELDING UNIT FOR OPERATION TIG – LIFT
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 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
(17)
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.
Holding the button
(3)
for about 5 seconds, we gain access to the locked functions of the
device;
11.
Press button
(3)
and hold it until
[BUTTON OF TORCH]
indication is displayed for selecting the
TIG-LIFT
contact arc starting function of the button on the welding torch. When button
(3)
is
released, after 1 s, the display will show the value of the current function. Set value [
LFT]
by
buttons
(1)
. If the
TIG-LIFT
contact arc starting function has been missed during the selection,
press button
(3)
again the methods are switched over and over again;
12.
Using the buttons
(1)
set the current basic parameter - welding current or parameter of the
selected function;
13.
The device is ready for use.
Enjoy Your work.
If required, perform the additional functions specified for the argon arc welding process (see Section 6.1).
