9.2 How to Change
●
Remove the set screw of the collet assembly and pull out the collet (rear).
●
Loosen the knob of the rear collet body assembly and remove the nozzle, collet body, tungsten electrode
and collet (front).
●
Insert the tungsten electrode (
φ
1.6) into the collet (for
φ
1.6) prepared, and then screw that into the collet
body (
φ
1.6).
(DO NOT forget to install an insulator.)
●
Screw the nozzle into the collet body.
●
Insert the collet (for
φ
1.6) into the rear collet body assembly.
●
Adjust the tungsten electrode extension to a suitable length according to the shape of weld zone and
weldment or adjust the electrode extension with an electrode adjustment gauge (option).
For adjusting method, see the item 8.6.
●
When the extension is determined, tighten the knob of the rear collet body assembly, and mount the set
screw of the rear collet assembly.
