The Characteristic of Spatter-Resistance Type
The hot arc from arc welding machine is adhesive even with metals or plastics.
Therefore, normal proximity sensor might have malfunction even though there are no sensing object if the arcs are put on
the sensing surface. The arcs are not adhered on the sensing part of the spatter-resistance type proximity sensor as the
part is coated with PEFE against thermal resistance.
Also, the protection cover sold optionally has the same function.
