Principle of operation
The arc is formed between the workpiece to be welded
and the emerging metal wire. The metal wire serves as
both an electrode and as a deposition material; It is
wound on a spool and is constantly inserted into the bur-
ner by wire guide rollers. The welding current passes th-
rough the wire guide tip of the burner to the electrode.
The inert gas exiting through the nozzle protects the
electrode, the arc and the molten bath against the sur-
rounding air.
6.2 Functional principle of wire feeding
The wire conveyor unrolls the weldment wound on a bas-
ket or mandrel spool and conveys it through the hose
package to the torch. When using basket coils, a basket
coil adapter must be used. Mandrel coils can be used
without adapters. The wire feed roller is provided with a
groove for the wire guide and must be replaced accor-
dingly when using a thicker or thinner wire. The contact
pressure of the pressure roller is adjusted via the pres-
sure control and should be selected so that the wire
spool can still be stopped by hand while the drive is run-
ning. For aluminum, the pressure should be as low as
possible, but still allow a safe transport of the wire.
