| 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. |
