DO NOT USE ANY liquids when cleaning the appliance! Liquids can enter the electrical sy-
stem.
Remark: Do not look into the arc while welding is in progress !
Remark:
Protect your skin, eyes and clothing gainst weld splashes.
Remark: Make sure that there are no combustible objects in the vicinity of the welding area or the weld
spark area.
Remark: Protect your ears against noise!
Do not move magnetizable objects into the vicinity of the welding set.
The welding process releases electromagnetic fields and, for example, watches, magnetic cards of all
kinds can be rendered useless through this.
Persons who carry a heart pacemaker must be made aware of these electomagnetic fields.
The possibility of the heart pacemaker being affected cannot be excluded.
Do not touch or put a hand into moving or live parts.
Description
Welding method
The welding method is capacitor discharge wel-
ding with tip ignition. No shielding gas is used, not
even for the welding of aluminium.
S
The welding stud is accelerated by the welding head to move at a speed of 0.5--1m/sec in the direction
of the base material. At the same time, the capacitor battery is switched on.
S
The ignition tip touches the base material and discharge current begins to flow. The ignition tip is hea-
ted up by high discharge current and evaporates all of a sudden.
S
The arc is ignited. It burns for some 1 or 2 milliseconds and melts on the base material.
S
The welding stud dips into the weld pool.
S
Heat absorption by the base material causes the weld pool to solidify.
S
The welding process is finished, leaving the stud firmly attached to the base material.
