4. ARGON ARC WELDING PROCESS (TIG)  

 

WARNING! 

As a protective gas, 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. 

 

 

4.1. PREPARING THE WELDING UNIT FOR OPERATION  

 
 
 

 

 

1.

 

Connect the power cable of the argon gas torch to connector socket B (-). 

2.

 

Connect the grounding cable to connector socket A (+). 

3.

 

Connect the grounding cable to the workpiece. 

4.

 

Connect the pressure reducer to the fitting of the cylinder with protective gas. 

5.

 

Connect the hose from the welding torch to the pressure reducer of the gas cylinder. 

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  the  welding  unit  to  the  outlet  of  the  power  supply 
system. 

8.

 

Set switch 7 on the rear panel of the welding unit to position I (switching on). 

9.

 

Press button 5 and hold it not less than 5 s to select the argon arc welding process 

(TIG).

 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 argon arc welding process 
has been missed during the selection, press and hold button 5 again for sequentially 
selecting the welding process required. 

10.

 

Set the specified welding current by buttons 3. 

 

If required, perform the additional functions specified for the argon arc welding process (see 

Section 6.1).
