lankasyöttölaite

Lankasyöttölaite, often translated as wire feeder, is a component used in welding machines, particularly in the MIG/MAG welding process. Its primary function is to reliably and consistently feed welding wire from a spool to the welding torch. This is crucial for maintaining a stable arc and producing a quality weld.

A lankasyöttölaite typically consists of a motor, gears, rollers, and a drive mechanism. The wire spool is mounted on a holder, and the wire passes through a set of drive rollers. These rollers are driven by the motor, which is controlled by the welding machine's circuitry. The speed at which the rollers turn determines the wire feed speed, a key parameter in welding.

The wire feed speed is usually adjustable by the welder, allowing them to match it to the welding current, wire diameter, and material being welded. Some advanced lankasyöttölaitteet may also have features such as wire straightening mechanisms or shielding gas flow control integrated into their operation. The quality of the lankasyöttölaite significantly impacts the welding process's ease of use and the final weld quality. A smooth and consistent wire feed prevents issues like arc instability, spatter, and incomplete fusion.
