5.4 TIG welding

5.4.1 Preparing the TIG welding torch

The TIG welding torch is to be equipped to suit the relevant welding task!
•  Fit suitable tungsten electrodes and
•  an appropriate shielding gas nozzle.
•  Observe the operating instructions for the TIG welding torch!

5.4.2 Welding torch and workpiece line connection

Figure 5-38

Item Symbol Description

Welding torch

Polarity selector plug, welding current cable

Internal welding current cable for central connection/welding torch.

• Connection socket for “-” welding current

Workpiece

• Insert the central plug for the welding torch into the central connector and screw together with crown

nut.

• Insert the polarity selection plug into the "-" welding current connection socket and lock in place by

turning to the right.

• Insert the plug of the workpiece lead into the "+" welding current connection socket and lock in place

by turning to the right.
