Ceramic Backing – OK Backing Concave
The semicircular shaped recess of the backing is particularly suitable for MIG/MAG welding with welding consumables that do
not have any or have only a slight amount of slag, such as solid wire, metal cored wire or basic flux-cored wire.

The semicircular shaped recess of the backing is particularly suitable for MIG/MAG welding with welding consumables that do
not have any or have only a slight amount of slag, such as solid wire, metal cored wire or basic flux-cored wire. The backing is
also suitable for circumferential seams with a minimum radius of curvature of 200 mm.
Instructions for use
Welding on ceramic backing requires a certain amount of practice. A trailing torch position and a minimum air gap of 4-5mm
must be used as well as careful welding parameter selection.
