1.17 Chucks (for insulation pins)
These chucks are used for insulating nails and pins
(order nos. see chapter 5.10).
1.18 Chuck extension
The Chuck extension is only used when using a centring
device
(see chapter 1.10; order nos. see chapter 5.10).
1.20 Welding on centre punches
Welding elements with ignition tip can be positioned for
pattern welding exactly on centre punches or scribed lines.
Since the welding process is started by the ignition tip,
marking must be performed carefully.
The arc cannot ignite on a centre punch struck too deeply.
Should it nevertheless ignite, then the strength of the weld
is questionable.
Therefore make sure that the depth of the centre punch
does not exceed 0.3 mm.
Note: You can rule out this uncertainty by using a so-called
automatic
punch (order no. see chapter 5.10).
