8.6 Electrode Adjusting Gauge (Option)
Electrode extension can be easily set, using an electrode extension adjusting gauge (L7622P: Option).
Since the rear collet body assembly can be separated from the torch body, electrode can be replaced safely
and electrode length can be adjusted from a distant place.
【
Adjusting the Electrode extension
】
●
Pull out the rear collet body assembly from the torch body.
●
Loosen the collet holder assembly, insert it into the electrode adjusting gauge of the rear collet body
assembly, and fix with wing bolt.
●
Set the tip of electrode to a bar.
●
Tighten the set screw and fix the electrode.
Fig. 8.2 Adjusting the Electrode extension
Note: 1 Grind the electrode before adjusting the electrode extension.
2. Scale plate “0” is set to 5 mm of electrode extension from the tip of the nozzle.
To adjust the wire extension, slide the bar and set to a desired value.
As shown in Fig. 8.3, when the bar is slid to the left, wire extension is long, and when the bar is slid to the right,
wire extension is short.
Note that there may be a slight difference in extension depending on tightening of the nozzle.
