1 Remove gas nozzle.
2 Remove welding spatter.
NOTE
• Replace the centering ceramics as soon as deposits become visible on
the surface. Deposits may result in a catastrophic high-voltage arc,
destroying the torch body.
3 Check wear parts for visible damage and replace them, if required.
4 Unscrew back cap and remove tungsten electrode.
5 Sharpen tungsten electrode as follows:
Sharpening the tungsten electrode depends on wear and must therefore be
carried out when required.

Sharpening the tungsten electrode
To sharpen the tungsten electrode, use a sharpening device with a diamond
wheel and the following functional principles:
• The point is sharpened longitudinally through the center axis.
• Automatic regulation of the tungsten electrode drive by gravity.
• Can be set for all electrode diameters.
• Offers continuous adjustment of the angle.
Clean the cable assembly by proceeding as follows:
1 Check screwings and plug-type connections for visible damage and tight fit
and replace them, if necessary.
