Abb. 4:  Gas connection

 

Â

Place the inert gas cylinder 28 in a suitable location 

and secure to prevent it from falling over.

 

‰

The cylinder can be secured using a wall bracket or 

cylinder trolley.

 

Â

Briefly open the gas cylinder valve 27 several times in 

order to blow out any dirt particles that are present.

 

Â

Connect the pressure reducer 22 to the inert gas cyl-

inder 28.

 

Â

Screw the inert gas hose 24 to pressure reducer 22 

and open the gas cylinder valve 27. 

Setting the inert gas quantity

 

Â

Open the valve 19 on the TIG welding torch. 

 

9

Inert gas flows out.

 

9

The  flow  meter  23  indicates  the  gas  quantity,  and 

the content pressure gauge 26 indicates the cylinder 

content.

 

Â

Close the valve 19 on the TIG welding torch when the 

torch is not being used in order to prevent unneces-

sary use of gas.

11.3  Electrode welding process
Connecting the electrode welding cable

 

Â

Connect the electrode welding cable to the minus 

or plus socket 8 and secure the cable by rotating it 

clockwise. 

The polarity of the electrode depends on 

the type of electrode and the welding proc-

ess. Please follow the manufacturer's in-

structions on the electrode packaging for 

this purpose.

11.4  TIG welding process

For TIG welding you require a TIG valve 

torch (Type LTV2600) for this device

Â

Unscrew the clamping cap 17.

 

Â

Remove the electrode 16 from the collet 18.

 

Â

Grind the end of the electrode 16.

 

Â

Slide the electrode 16 into the collet 18.

 

Â

Insert the electrode 16 into the torch and firmly tight

-

en the clamping cap 17.

Do not dismantle the collet body 20 and the 

gas nozzle 21.

When converting the torch to a different 

electrode diameter, please pay attention to 

the following.

 

‰

The collet 18, collet body 20 and electrode 16 must 

have the same diameter.

 

‰

The gas nozzle 21 must be matched to the electrode 

diameter.

Connecting the TIG torch

 

Â

Connect the TIG torch to the minus 8 connection 

socket and secure it by turning it clockwise.
